I have a Samsung Galaxy S4 and every so often, without any apparent reason, while my phone is idle sitting on my desk (no dock or anything; it's just laying on my desk) the screen will light up and display the time and the icons of my any current notifications appear. I have disabled daydream and unchecked "Desk home screen display" It appears to happen randomly after device has been idle for some time. It's not a huge deal, but it's annoying and rather distracting. My device is a rooted Verizon Samsung Galaxy S4 running android 4.2.2 on baseband VUAME7. | Go to the air gesture settings and deselect "quick glance" | Desk home screen display appears randomly even when disabled | android |
Is there a way to extract a log file containing all keyboard history, and everything that has been typed, from a Samsung Galaxy S3? | You need to first install a Key Logger on the device (Which will need to be rooted for full functionality) and then you will be able to log all key strokes. There are several apps that offer that. P.S Using keyloggers to spy on people is illegal in most countries. | Extract Samsung Galaxy S3 keyboard history | android |
The Google app requires a menu button (like I have on my Galaxy S4) to access options menu and edit Google Now settings. However, on my Nexus 10 I do not have an option button. Most apps have the "3 Dots" button in the top right to replace it, but the Google app does not have this! How am I supposed to access the options menu in the Google app on my Nexus 10? | The overflow menu for Google Now (on all form factors, I believe) is in the bottom right corner of the app instead of the top right, where most other applications put it. You need to make sure you've scrolled all the way to the bottom of your cards, though, because it shares the bar with the "Show more cards..." button, which is hidden if your screen is full. | How to access Google Now settings on Nexus 10? | android |

What are the criteria being used to decided which apps go into the trending apps lists on <code> Google Play </code> ? When I look on the trading lists, I don't see a lot of consistency, I see apps with as little as a 1000-5000 downloads and others with 500K-1M downloads. I guess the real question is, any idea what Google takes into consideration when deciding what's trending? | If you have developed and Android app, then you must have gone through http://developer.android.com . Where the basics are taught about the android. Lets see how, there are generally three tabs, but we will talk about the last one Distribute . In that section it is clearly taught how Google gets an app in Trending portion. http://developer.android.com/distribute/googleplay/about/visibility.html its the link! The main factors are: Ratings, Downloads and great apps that users are providing a great feedback with are mainly on the top of the Trending Apps, but there are two type of trending app sections, Free and Paid! So make sure you are viewing the section that is mainly for you! That's all what Google would use. 1. Feedback 2. Ratings 3. Downloads 4. Content. | Getting into the trending list | android |

Thanks. | You might want to check on android.com, which contains the list of apps included with each version: 1.1 1.5 (Cupcake) 1.6 (Donut) 2.0 (Eclair) 2.1 (Eclair) Unfortunately, they stopped that listing after Eclair (2.1).

Is there a way to block (or mute) all calls except for those on my contact list? Im using android 4.1.2 o samsung galaxy s3 mini, thanks in advance | The app Blacklist Plus mentions exactly that as one possible use: There are four block modes of call blocker: Blacklist All except the whitelist All except contacts All numbers (emphasis mine). There are plenty other similar apps available, just search for "blacklist" or "call blocker" on the playstore. | Block calls for everyone except for contacts | android |
I wonder if there is ability to replicate this feature from iOS : In iOS you can turn on Accessibility function that add the "Speak" button to the "selection menu". And if you click, it would turn on Text To Speech engine and read selected text. Can I do the same thing in Android ? Thank you very much in advance PS: I assume that regular app could not modify "copy, paste, cut menu" so I probably need custom ROM. | Maybe not exactly what you had in mind, but coming close: There are several clipboard-action apps available which might come close to that. I didn't try them, so no guarantees – but their descriptions are promising they can do that. Two examples would be: Speaklip Auto Speak Clipboard 2 Hopefully one of them proves helpful to you. Good luck! | Text To speech feature on selected text | android |
I'm trying to troubleshoot a problem with an unwanted pop-up message, and the person who's trying to help asked what kind of pop-up it is. It's just a message on the screen, what difference does it make? And how do I tell what kind it is? | Android has different ways for apps to give you information or get your attention, and they all have different names. App developers need to know the differences, and when to use each one, so they can code the correct behaviour in their apps. Even as an end user, if you want to troubleshoot a problem, find which app is giving you messages, or describe some behaviour (for example, when reporting a bug to a developer), it saves you time and confusion if you can call each thing by its correct name. Notifications Notifications are the most common feedback mechanism on Android. They look like icons in the top-left of the screen (the notification bar). On Honeycomb and ICS tablets, they instead show up in the system bar, in the bottom-right next to the clock. In Jellybean and above, once you've expanded the notification drawer (like in the screenshot), you can long-tap a notification to get a menu with one item, App info . Clicking this item tells you which app is responsible for the notification. You can also stop this app showing any further notifications from that screen. Some apps create notifications to advertise things at you. This is now (since September 2013) banned under Google Play's rules, so you should report as malicious any apps that do this, from the app's page in the Play Store app. Often your phone will play a sound or will vibrate with a notification, but not always: it's up to the app which created it. Toasts A toast is a small message that shows up in its own box near the bottom of the screen, and disappears on its own after a few seconds. It's usually a response to an action you've just performed, but in fact a toast can come from any app, not just the one in the foreground. A toast can't interact with you (you can't click on it or type into it), so there's no need to worry about it "stealing focus" like on a PC. There's no indication of which app created the toast. Dialogs A window that appears, with buttons you can click or a list of options to choose from, is called a dialog box , or dialog for short. (It's spelt the American way even in British English.) They almost always relate to the foreground app. Strictly speaking, from a developer's point of view a "dialog" is any non-fullscreen activity window, but they're usually used for simple confirmations or choices, like in the screenshot. Interstitials In the marketing world, an interstitial is a page or screen that comes in between two others. They're commonly used to show large-format ads in ad-supported apps and games: you click a button in the app, and an interstitial shows for a few seconds before you get to the next screen. Summary Next time you want to discuss or troubleshoot some kind of message that pops up on the screen, you'll know what to call it, and you can make it easier for others to help you. | Popups, dialogs, notifications, toasts: what's the difference? | android |
Can Tasker launch an app's shortcut as an action? I can't find "Shortcuts" as an option in the "Select Action Category"-dialog when creating a new task. This works without problems in Locale. | Strangely, this does not appear to be possible in Tasker, by default. However, I see there is the AutoShortcut app on Google Play which is meant to allow it. Interestingly, Tasker itself will tell you about AutoShortcut (complete with a link to Google Play) if you press the magnifying glass icon when attempting to add a plugin action to a task (I'll update this answer with screen shots when I get around to it). Theoretically, it should also be possible using the <code> Send Intent </code> action, but that seems way more complicated than should be necessary for such a simple task. If AutoShortcut doesn't work for you, let me know, and I can try to figure out what the Intent settings should be. | Launch a "shortcut" in Tasker? | android |
Summary : Is there a way to stop the Samsung Galaxy S4 screen from turning on when receiving text messages (without disabling the notification light)? Details : I've got a Samsung Galaxy S4 on Verizon. I've noticed that sometimes when it's in my pocket that it will turn on and access apps, etc. (for example one time I saw it had posted something to Facebook). I think that the problem is when I receive a text message that the phone turns on and then from there the touch screen might do whatever it wants. The reason I think the phone screen turns on when I receive a text message is I've noticed that happen sometimes. So really what I want to do is prevent the phone from turning on in my pocket, but I don't think that is an actual option. But I thought there should be a way to stop incoming text messages from turning on the screen, while still allowing the notification light to flash. But I haven't found an option that does that. | It looks like having the screen turn on when SMS messages arrive is a stock feature of the Samsung Galaxy S4 on Verzion (possibly applies to other models and carriers as well). I saw threads here and here discussing the problem. There is no setting to disable only the screen turning on. The workaround that I ended up using is as follows: 1) Disable notification in the stock app: go to settings and scroll down to Notification settings and unselect "Notifications". 2) Install SMS Popup . 3) Enable SMS Popup. Then go to Addition Settings and disable "Screen on for Popup". Maybe someday Samsung/Verizon will fix the problem, but for now this workaround seems to work for me. | Stop from Samsung Galaxy S4 turning on when receiving text message | android |
I know that Galaxy Note 10.1 has multiple editions (one of them is LTE chip). Can it make and receive ordinary phone calls? Like using ordinary signals, instead of the Internet ones.

I have an app which is currently in beta testing. With every new version I have to send it to the users, they have to download it, uninstall the previous version (sometimes), and then install the new one. Is there a way to update an app without it being in Google Play? | You might provide them a link! A link on your website, that would provide them with the .apk file. After downloading, the user would install that file in his android phone. After installing, the previous version is auto-deleted and the new version is installed! User data is saved. But I have never used the developer tools from Google Play. So I am not sure, whether the Google would mark it as spam or not, because some user try out Verify And Install instead of Package Installer. Verify and Install is a Google service to check whether the app is spam or not. So I think, if the user tries Verify and Install instead of the built-in installer, he might get some errors, saying this signature is not found on Google Play! Or something like that. But just my guess, if your beta is placed on Google Play, then they won't show up any errors, as they would find a signature on Google Play too. Hope I am not wrong: Because I have never used either Verify and Install or Google Play Developer tools. So I might be wrong somewhere. But still there is a functionality to install apps, but that also depends whether the user is allowing the installation of Unknown Apps (Apps which are not downloaded from Google Play). | Update an app that is not in Google Play | android |
I am running Paranoid Android and love it, but it is hard on battery life. So I am looking at flashing back to AOKP. In looking around, I've seen some vague references to a "Permission Management" ( such as mentioned here ) in the latest AOKP... but after googling for a couple days, can find no real details on it. Is this something that is in the current stable builds of AOKP, or is just referring to the built-in one from Android 4.3 in the latest AOKP nightlies? If anyone can point me to an article with a some good information on this feature and its current build status, I'd be very grateful. Been missing this functionality since LBE Privacy Guard died with Jelly Bean. Mind you, I am aware of other options such as LBE, PDroid, XPrivacy. I'm looking specifically for more information about AOKP's permission management. Thanks! | Well, I've gone and flashed over to AOKP, so figured I'd update this with an answer about their Permissions management. It is found towards the bottom of the root Settings screen. For each user-installed app it lets you turn off specific permissions. Essentially a very basic version of what LBE Privacy Guard used to let you do. Some features that are missing: Ability to group by a permission (e.g. <code> Access Location </code> ) and see all apps that use it with ability to disable them in this view Ability to change permissions on system apps (e.g. camera to disable geotagging completely) So all in all, it's a nice feature, and more than available in most ROMs I know of without extensive modding/flashing of additional frameworks and things. Potentially the 2nd item above could - at least in some cases - be gotten around by using something like ROM Toolbox to convert the system app to a user app... but I'm not sure what other ramifications doing so would have. | AOKP Permission Manager? | android |
There are quite a number of applications that came pre-installed onto my phone when I bought it. I am unable to uninstall any of these without rooting my phone. Every now and then, Google Play will send me notifications of new updates for these software. Some of these, such as Gmail, YouTube and Hangouts belong to Google, others belong to third parties linked to my telco. Whenever I perform an update on an application, I have to go through a list of App permissions and decide whether to grant those permissions. Some of these may request permission to access my address book, others may request certain controls on my Android system. These are privacy issues as well as security issues that I supposed many people will be facing. In any case, how should one deal with these "unwanted" programs? | You might consider disabling those apps (starting with ICS, that's possible for some but not all). This way you'd solve multiple of your issues: no more update reminders app becomes unavailable, so it's no longer shown in the app drawer being disabled, they should also no longer provide an "attack vector" If that's not possible for some apps via Settings → Applications (check the "All" tab there to see pre-installed apps), and rooting is an option, you can still freeze them with apps like Titanium Backup to achieve the same. | Should I update those pre-installed programs that I never use? | android |
I want to buy a mobile Bluetooth keyboard. It seems Apple ones are easier to find. Does it make much difference? (I assume the connection is the same for similar models, and the issue is layout) | I have used a couple of different BlueTooth keyboards and they all work pretty well on Android. I would assume the Apple keyboards would work just as well. I am a fan of Logitech keyboards just because I've always used them and they have always worked. You can always just buy an Apple keyboard and if it doesn't work you can just return it. | Can I use a keyboard for Apple? | android |
When I plug in my headphones, an Earphones page appears on my device with the title "Enjoy listening to your device", which is part of page buddy. I have a music widget and a video widget, which is fine. My first two applications are fine, Firefox and YouTube, but my last two applications are Messaging and Email . Apparently it's supposed to be frequency of use, but I never use the Email app, and neither the Messaging app nor the Email app are aural. When I try to change these two apps, it says "Cannot edit recommended apps". Can I fix this to stop displaying non-aural apps? | it's the most frequently used apps while the earphones are plugged in. just open the app you want to show up 4 or 5 times in a row while the page buddy is active (earphones plugged in) and it will show up in the recommended apps. repeat for the next 3 apps you want to show. There's usually 4 recommended apps. This goes for all of the page buddy pages, earphones, docking, roaming, and spen (on supported devices). | Can I override page buddy's recommended applications settings? | android |
I wonder if there is a way to use "Google Play Music" with something like a "Party Mode". I just want to give my friends the possibility to browse and play my music library without giving them access to my entire Google Account. They clould use the Web app with my laptop or the Android app on my MK808. Maybe I'm using the wrong terms for searching but I coldn't find a thread with a similar problem. I can't imagine that no one else wants to do that... Do anybody know a solution for this problem? | Thanks for your answers. I found a solution for my problem.

I have a Samsung Galaxy S3 with Android 4.1.2 (standard, not rooted). I previously had an iPhone, and the feature I miss the most is the ability to go directly to the camera from the lock screen without having to type in my PIN. How do I do this on Android? I know that there are at least two or three questions asking pretty much the same question. Unfortunately, I don't have the reputation to comment on those answers to explain why they don't help me: stackexchange-url ("Is it possible to use the camera without unlocking first?"): stackexchange-url ("How to enable a PIN but allow quick access to camera?") For both of these posts, the accepted answers recommend WidgetLocker, but the persons who gave the answers had apparently never tried it themselves. I've tried at least five different free lock screen apps, but none of them solve my problem--they all still require a PIN to use the camera. I haven't tried WidgetLocker, but I'm not going to pay for an app that I'm not sure will work, especially when all the others I've tried don't work. Does anyone know for sure that WidgetLocker resolves this problem? I also bought and tried WidgetLocker, but it doesn't support PINs at all, and so it is not a solution to this problem. stackexchange-url ("How to use camera without unlocking phone? (Jelly Bean on S3)"): This answer suggests using Samsung's built in motion. I tried this, and it still requires the PIN to access the camera. This answer doesn't resolve the issue. I'm certainly willing to pay for an app that solves this issue, but I don't need any other lock screen features--I just want rapid access to my camera. Also, I would prefer not to root my phone just for this, but if there is a solution via rooting, I would seriously consider it. Can anyone please suggest an answer that really works? | There is no way in Android to access to the standard Android camera from a password-protected device.

I want to create a few simple macros which I can activate while driving. At the moment, for safety I would need to park the car in order to use the GUI. What I'm after (if it's possible) is to assign to a trigger (such as shaking the phone, which I can do while driving without taking my eyes off the road) to a series of taps or the clicking of a button etc. Can one app control another in this way? And can macros be recorded which would for example, click on an item in a list, and then when a new screen pops up, click a GUI button in it? Specifically, I listen to a number of di.fm radio station streams in the car and want to be able to change between them. DI.fm has a custom app for this, but their stations are also available as standards-compliant streams (mp3, aac) for 3rd party programs like WinAmp (which might have more accessible controls for switching between streams which could be managed by an additional 3rd party app) | Tasker can do that (and a lot more things), as long as the app in question supports it (a list of apps with Tasker support can e.g. be found here − never mind the German, if you're just after the list). As you've described, it supports "Shake gestures", and if your device has a camera button, you could utilize that as well. "Flip gestures" might also come in handy (flip the device to face down, then face up, etc.) I know it's a paid app. But to try it out, visit the app's project site and get a 7-day trial (remember to export all your configuration and profiles before "day 7", then you can simply uninstall, re-install, and re-import your settings for another 7 days period − this hint comes from the dev himself, so it's nothing bad ;) The app needs some time to get warm with it. But once you did, you don't want to miss it anymore :) | Control of apps while driving. (Macros?) | android |
I have a brand new 10.1 inch tablet, made in china. The screen doesn't respond to touch as much as it should, a few other little things and I can't work out some of the onscreen operating icon/button things. The resellers suggested I start with Android Central Forums, as this is the only Android devise they sell so they don't know the answers. I joined up with A.C.Forums, but can't work out how to post. Help and/or advice would be very much appreciated. Thanks | There's an easy way to check if the tablet has a faulty touchscreen. Go into Google Play and install a painting app. There are many free painting apps to choose from: just pick a simple one. Run the app and try to paint the whole screen. If the painting doesn't follow your finger, or any parts of the screen can't be painted, you can see the screen is faulty, and you should return it to the seller for a refund or exchange. Faulty touchscreens are quite common on cheap Chinese imports because they use cheaper components and don't test them thoroughly. The other possibility is that, being a cheap tablet, it has an old-fashioned resistive touchscreen instead of a proper capacitive one. You can tell by using a pointy plastic stylus (such as the handle end of a toothbrush, or the non-writing end of a ballpoint pen) to click on something on the screen. If that works, it's a resistive screen, not a capacitive one. You'll find any swipe gestures a lot harder to perform on a resistive screen, and multi-touch gestures like pinch-to-zoom are not possible at all. You'll find a resistive touchscreen is a lot more responsive to being pressed with your fingernail instead of the flat 'pad' of your finger. | screen not working properly on my tablet | android |
I have a Google searchbar in a tablet I have borrowed For me it's in a very inconvenient location and I keep on pressing it accidentally. It looks like I can't click and drag on it to move it to another location either. How do I hide this toolbar? I need to be able to get it back as well, since the tablet isn't mine, but I want to hide or disable this search bar while I use it (or at least move it to another location) | The search bar is a built-in part of the default launcher and can't be moved or disabled. The least invasive way to get rid of it is to install a new launcher of your choice and use that instead of the default one. The old launcher is still installed, and will come back when you uninstall the new one, so the question is just whether you ought to install software on this device you've borrowed. | how do I get rid of this google searchbar? | android |
My usual listening habits are to listen to podcasts with Doggcatcher sometimes followed by listening to some music (currently using PlayerPro) (on my Samsung Galaxy S4) while driving. Periodically, when I close Doggcatcher and open PlayerPro, and I select a track to play, the track looks like it is going to start to play. However, although the timer starts at 00:00, and the Play button changes to the Pause button, there is no sound. Often the timer will tick over to 00:01 after a few seconds but it gets not further. Similarly, if I switch to the Google Play Music app, the timer happily ticks away, but no sound comes out. Switching again to, say, N7, we are back to the same PlayerPro behaviour. It appears not to depend on the media player, though I usually use PlayerPro. It usually happens after using DoggCatcher, but then again, it is the only app I use for podcasts. The only solution I have so far, is to restart the device - a bit inconvenient, particularly when driving. Has anyone else experienced something similar? Any idea what is cause these media players to 'pause'? Any tips on investigating this issue? | I had to rebuild my phone after a firmware update; in doing so, I skipped over a lot of the Junk that I'd previously installed. The upshot is that I no longer suffer this problem (nor several others that had crept in). While it could be the software update that was the solution, I suspect that it was more likely that the clean install that did the trick. On the plus side, the problem has disappeared; on the negative side, we don't know what the solution is. | Media Player stuck on 00:00 (randomly) when opened | android |
I have Droid 2 Global (droid2we) and I've tried Power + Volume Up, but that doesn't load any recovery mode. I've also tried Power + X but that loads the standard Android System Recovery <3e> , which won't install unsigned zip files. I can load the Bootstrap Recovery app which will let you reboot into Clockwork Recovery mode, which does work. However, that requires a functioning system which makes it a pointless way to launch a recovery mode! | I found that the following sequence works: While on, run <code> adb reboot recovery </code> from command line. This will restart into standard Android recovery. (If your device is not seen, start at #2 and come back.) Take battery out. Unplug USB. Hold power down for 10 seconds.

I Installed CyanogenMod 10.1.2 in my Galaxy S I9000 using Semaphore CWM Recovery v5.0.2.7 following this guide: http://wiki.cyanogenmod.org/w/Install_CM_for_galaxysmtd Before flashing the new ROM I made a backup using Semaphore CWM.

I have an HTC Sensation XE and the smartphone is becoming slower and worse every day, expecially compared to my Nexus 7 and Samsung Tab 2. Android on the phone is slow and lagged ( I have to wait even 6-7 second after clicking somewhere), the battery depletes very fast and the phone itself becomes very hot if I do something "intensive" like using google maps. the Android version on the phone is 4.0.3 and as far as I know, there is no update. What can I do to improve the phone? It's market value makes it not worth to sell and it is still working, so I would like to find a way to fix it somehow, what can i do? I like a lot the vanilla Android of the Nexus 7, there is any way that I can put a plain android on the HTC, keeping all the functionalities?

Please could someone correct my understanding? I read that once a phone has a custom ROM loaded, the play store can not be used on it again. However after more reading I'm not sure if this is the case? I'm sure the answer is complicated so to simplify it, all I want to do is convert an old phone (HTC wildfire) into a dedicated device for my toddler that will just be used for offline games. I don't need to remove features as he will be supervised, but I don't mind if the barest of ROMs is loaded as long as I can load games from the play store: I just want to speed the phone up, as at the moment it is awfully slow. (I have already tried restoring to factory settings and installing updates.) Help would be appreciated! | There is no such restriction. I use custom ROMs on two of my devices, and the Playstore is acting normal. The only problem you might face is that the Google Play App won't come pre-installed. You need to flash a package called "GApps", which must match the Android version used by your custom ROM. Usually, the corresponding links are pointed out on the page where you download your ROM from. | Restrictions of Play Store on custom ROMs | android |
I am android game developer, really wanted to capture nice quality video preview of my game for promotion purposes. And my question is, If I would connect by android device (Samsung Galaxy S3 or Nexus 7 tablet: using micro USB HDMI adapter with my PC, like this one for example: I know I would be able to see what on my PC what I do on my device, but the point is, would I be able to turn on software responsible for capturing my desktop like Camtasia studio meanwhile to be able to record it? Thank you. | This is only any use to you if your PC has an HDMI input , which is very unusual. You'll only have such a thing if you deliberately bought video capture hardware and attached it to your PC. If you have such hardware, you should use the video capture software that came with it. Trying to use Camtasia to capture it would be like trying to use Camtasia to capture from a webcam. In addition, depending on what adaptor you use, your video capture hardware may also need to support MHL (the wire protocol used to send video data over the micro-USB and HDMI connectors).

I have suffered a good deal of OS crashes seemingly as a result of Chrome 29.0.1547.59 (Interface locks up, mainly when switching back to Chrome after doing something else, and having the tabs visually "swish" back into the tab bar) running on unrooted Android 4.2.1 (Nexus 10). However, unlike this last time, I usually get back all my tabs. So, as I would do on a Desktop OS, I went looking for the session store, to no avail. I am yet to even find the bookmarks file.

It seems to be fairly well established that the Nexus 4 has had issues with not supporting USB OTG since launch (e.g. this bug report ). From what I've read it's both a hardware and software issue. The hardware can't supply the necessary power and the software does not conform to the protocol in some way.

Summary: Route navigation crashes on starting of route finding. This is an intermittent bug. It only started happening recently - I think it coincides with when on a desktop browser I volunteered to start using the new version of Google Maps.

How can I configure the navigation app on my phone to use only the more stable mainstream navigation app?

Are there any third party apps which have route navigation similar in quality to that of Google's? Thanks | After you enter the starting point and destination, the app gives you the possible routes.

I have a Samsung Galaxy S4 that I had for a little over months before getting caught outside in a serious rainstorm. As I was pulling the battery out of the phone, I noticed the screen flicker. I pulled the battery and left everything in rice for a few days after the fact. Upon powering up, it appeared that the phone was still working, except for the display. It would buzz when I got an email or a text, and it would ring when called. I'm fairly certain that my problem is simply that the LCD and/or digitizer has gone bad. I've found the replacement parts that I need to replace those, but before I drop the cash on it, I'd like to know for sure that everything is else is working as it should (camera, IR, wifi, etc). I've found a couple of apps that do hardware diag, but since I can't really interact with the device, they aren't a lot of good to me. Does anyone know if there is any sort of hardware diagnostic that can be run through the ADB shell? | Investigating in this issue, we already have a lot of stackexchange-url ("broken screen questions") providing some clues: You could hook your device to your TV screen via HDMI. This should mirror its (invisible) screen. Of course this would require your screen at least to respond to touch events.

I have noticed that 3 of my Android phones heat on low signal (Nexus4, Xperia U, and HTC One) 40~50C. My friend has an iPhone and it doesn't seem to heat as much (30C). So, why does this happen? Why does low signal drain my battery, and why does it heat too much? Could it be solved by software? or is it a hardware problem? | Why? When the phone signals are weak, the android OS constantly scan the area thoroughly. This requires more battery power. That's the reason your phone gets so hot when you are in areas with poor reception. Could it be solved? That is the reason it is advised to turn flight mode on when you are is low-signal areas to preserve your battery life. Is it a hardware problem? Yes. and that problem is common to all the android devices. So nothing to worry. Why not iPhone? For the comparison with iPhone, the specs of android device of each manufacturer varies from one another whereas it doesn't in apple deceives (Not everybody get to produce a device which can run iOS, thanks to the Apple Inc. patents.)

I remember my old Nokia 3310 took about a minute after booting before the phone book (and other SIM card functions) became available. The problem wasn't really noticeable on early Android phones because they took so long to boot anyway. While the phones are a lot quicker now, the SIM cards are still the same old technology.

According to a colleague who has the new Nexus 7 (2013) model already, there is a GLONASS sensor in addition to the GPS one in the device. Is this true?

Please state your sources in your answer(s). | According to Ifixit's teardown, the Nexus 7 2013 uses the Qualcomm 8064 Snapdragon S4 Pro SoC. Qualcomm's specs show that SoC uses their IZat Gen8A GNSS chipset, which according to their overview does include GLONASS support, though this doesn't necessarily mean GLONASS support is actually active and available in software. A simple means to test whether you've got GLONASS is to use GPS Status and Toolbox and see how many satellites it shows for you.

So I thought it would be a great idea to try and root my brand new 2013 Nexus 7. After checking out a few tutorials online, I found one for mac, and downloaded the toolkit at: http://www.androidrootz.com/2012/12/nexus-7-one-click-toolkit-for-mac.html I opened up the bootloader by holding down Power + Volume Down and opened the included script on my computer, which unlocked the device. I then attempted to restart it into recovery mode. I pressed Power + Volume Down on startup and opened up the bootloader. I then scrolled to Recovery Mode using the volume keys and pressed Power to select it and boot into recovery. This is where everything went downhill. I could open up the bootloader, but when I attempted to boot into recovery to load SuperSU onto my device, it got stuck on the Google logo with an unlocked padlock icon at the bottom of the screen. So I tried to boot normally, and it got stuck on the same screen. All the forum posts I have come across so far to fix a bootloop all require the ability to boot into recovery mode or normally. I cannot find a guide that tells me how to relock and return to factory settings if I cannot boot at all. Basically I need to unbrick my 2013 Nexus 7. | Thank god I figured out how to fix it. The problem was that I was using software that was meant to root a first gen Nexus 7, and I had the second gen (2013) version. Whoops. In order to fix it, I downloaded the Unroot/Stock Toolkit from http://www.androidrootz.com/2013/08/nexus-7-one-click-toolkit-for-mac-2013.html and then downloaded the factory images for the Nexus 7 2013 from Google's site, https://developers.google.com/android/nexus/images#razor I then used the Unroot/Stock Toolkit to reload the bootloader and factory image.

I'm trying to make my nexus 4 sharing its internet connection with other devices. First I've tried with the portable hotspot: when it is ready I try to connect my nexus 7 2. It connects without problem to the WiFi Net but the WiFi indicators never gets blue and I'm not able to surf. Then I've tried the bluetooth way: paired the devices and (on the tablet) checked the internet access option. This time the bluetooth indicator gets blue but whenever I try to load a page the browser loads forever. The same happens with a macbook.

How do install binaries? This is the program that I am trying to install http://sourceforge.net/projects/base64/ | So what 'Access Denied' in this case is you do not have the correct permissions to execute the file. This can be solved 2 different ways: use the <code> sudo </code> command (super user can run any file) sudo myprogram -options param1 param2 param... use <code> chmod o+x filename </code> to let anyone execute the file so basically you need a rooted device to be able to run that file, unless you change the permissions of the file before you transfer it to the device. You can use the <code> chmod </code> command to add the execute permission to the file before you hand it off to the device. This way anyone can execute the file. Be warned, adding the execute permission for everyone is a security hole if the program can be used to change the file system in any way. Rooting your tablet in this case might actually be safer. | how to install command line programs | android |
I have been having this issue between ROMs, as well as between connections. I am currently running ParanoidAndroid 3.94 (Android 4.3) with franco.kernel 3.0.89. Other apps consistently update fine. The error I get is Update for "application-name" could not be downloaded due to an error. (403) I have eliminated the following factors: Network issues (issue persists with two separate Wi-Fi points, as well as mobile data) Google Play cache issues (I have cleared cache and restarted the Play app) If I "sacrifice" one of the apps that do not work and uninstall "TuneIn Radio Pro" from Play store — I am then also locked out of actually getting the app back on my phone.

However, after the installation starts, I get the following error message: Error: Package file is invalid Now, I am able to get all of these apps just fine on another device I have (Nexus 7), so I appreciate the fact that there is something up with my phone that causes this.

A friend of mine has a Nexus 7 2012. Although it used to work, it now won't turn on.

Thanks I've reffered Official Links Android setting up ADT , [Managing AVD's with AVD Manager][2] See screenshot of Errors Click here | Ok so it looks like you are not trying to run it properly. First things first you need to create an Android Virtual Device (AVD). This will be the profile of the device you will be emulating. Open up a terminal and follow these steps. Make sure you have the SDK installed and you are in the <code> ./tools </code> directory of your SDK. For this example I will be creating an AVD named "Nexus_7". Step 1: determine your target: <code> /.android list targets </code> You will get an output of all of your available targets, here is the one I will use: <code> id: 3 or "android-18" Name: Android 4.3 Type: Platform API level: 18 Revision: 1 Skins: HVGA, QVGA, WQVGA400, WQVGA432, WSVGA, WVGA800 (default), WVGA854, WXGA720, WXGA800, WXGA800-7in ABIs : armeabi-v7a </code> Step 2: Create the AVD: <code> ./android create avd -n "Nexus_7" -t 3 </code> For simplicity, when it prompts you to create custom hardware specs, just enter (or enter no then press enter). You should get output like this: <code> Created AVD 'Nexus_7' based on Android 4.3, ARM (armeabi-v7a) processor, with the following hardware config: hw.lcd.density=240 vm.heapSize=48 hw.ramSize=512 </code> Step 3: Launch the Emulator Here is the moment of truth: <code> ./emulator -avd "Nexus_7" </code> It will take quite a while for the emulator to start, especially on the newer Android builds. You can screw around with hardware acceleration if you want it to move a bit faster. Also you should use Screenshots to speed up the boot time.

I've got a stock, non-rooted Nexus 4 which I updated to Jelly Bean 4.3 when the OTA update came out a month or more ago. Just today I got another message that there was a system update available. It said it would update to 4.3, and I double-checked (and took a screenshot), and confirmed I already had it in "About phone." Nonetheless, I went ahead with the update to get rid of the notification, and it went through the usual process. The before and after screenshots of the about screen confirm that I had the exact same Android, Baseband, and Kernel versions, as well as the same Build Number. I can't find any differences after the update. Does anyone know why this might have happened?

When I go to Android Device Manager , my tablet is listed, but not my phone. I had signed up just as soon as ADM was available, and at that time both devices were listed. Now, for the last several days, I can only see my tablet. (For what it's worth, both devices appear in the "My Devices" section of the Google Play Store.)

I have followed these steps, but it doesn't appear to have worked. | Well, I don't seem to have an answer why this was happening, but I got some advice about how to finally fix it. From Ryan Lestage on Google+: Clear data for the following apps: Play Store Download Manager Google Services Framework Restart your phone. Fire up the Play Store app. Wait for the device to show again on the web Play Store. It will appear under <code> Settings > Devices </code> . It may take a half-hour to several hours to appear. When your phone has shown up in the Play Store with the date registered as today's date, proceed with the next steps, but not before. Open Google Settings from your device's apps menu.

Note that this action doesn't remove personal data. Go back to Google Settings and select Allow remote factory reset. Restart your device. I would like to know exactly which of these steps was the magic sauce, but I'm content that it worked at all. I suppose that Play Store connection makes some sense, because while my phone was listed there, it showed a "Last Used" date back in March or somesuch. I really hope that the setting sticks this time, and that I won't be forced to repeat this process every couple of months just to protect my device. (If so, I'll go back to some of my other options, like Carbonite and/or Lookout.) | Phone not appearing in Android Device Manager | android |

I have Tasker speak texts to me if the phone is not in silent mode.

This works well except when I'm on a phone call and the text is read out while I'm in conversation! Doesn't happen much but it's annoying. So what I want to do is have it read out texts when I'm not in silent mode AND when I'm not on a call.

When creating an emulator device, the option <code> Emulation Options </code> makes me confused. What do <code> Snapshot </code> and <code> Use host GPU </code> mean? | The Snapshot option speeds up the boot of the emulator by saving a snapshot of its RAM once it has booted, and restoring from that snapshot on future uses. That way, it doesn't have to run the boot process (which is slow, because it's emulated) every time you start the emulator. The Use Host GPU option uses the host computer's OpenGL implementation (which is probably hardware-accelerated, on your real GPU) to evaluate OpenGL commands inside the emulated system. Put another way, when a program inside the emulator uses OpenGL for graphics operations, the work goes out to your real GPU, and the result goes back into the emulator, instead of emulating a GPU (which is very slow). The result is a significant speed-up, especially when you consider that most view and canvas drawing uses OpenGL in Android ≥ 4, even in non-graphics apps. You can't have both options turned on at once. | What is `Snapshot` and `Use host GPU` emulation option(s) for? | android |
I wonder if other people can read my contact list when the app permission(s) has <code> Phone Calls </code> permision like below snapshot. | Not quite: this permission allows the app to read the IMEI of your phone, your phone number, your network operator, and to know whether you are making a call. It does also let the holder of the permission know the number at the other end of the call, but not any of the contact data associated with that number. These uses are described in the developer documentation for <code> TelephonyManager </code> . A good use for this might be to disable some ongoing process while you're in a call, or show an indicator, or to help you report your device as stolen. A bad use for this would be for invasive ads to track your identity across different apps, in order to push targeted advertising at you; or to record your phone number and those you call, to make nuisance calls to you afterwards, maybe claiming to be from your network operator.

I have a chess app on my 2012 Nexus 7 (running stock Android 4.3, with a few small background services) that allows me to set the size of an internal hash table used by the chess engine. Larger hash tables increase the performance of the chess engine, but it is ultimately limited by the RAM available on the tablet. Typically, the Settings app indicates that around 450-500 MB of RAM is free. How much memory should I allow the app to use, and how much should I leave free for the system? As I don't want to change this setting too often, can I rely on this amount of memory being available every time I use the app? (Note that the amount of memory used must always be a power of 2.) The other questions and answers I've read haven't really answered this question, so I don't believe this is a duplicate. | If you've read around, then you'll already have read that the idea of "free RAM" is a bit of a nonsense for Android. PC operating systems take an app out of RAM as soon as you quit it, which leaves empty space that the PC probably has to spend power on filling again afterwards - probably with the same app next time you run it. Android tries to avoid this waste by leaving apps in memory after you stop using them or after they finish running, so that they're ready to run again next time. If it needs more RAM for an app, only then does it get rid of these cached processes . Android will first get rid of cached processes, based on how soon it thinks it's going to need them again. If it still needs more RAM for the foreground activity, it'll get rid of background services (which sync your email etc. but aren't directly visible). If it still needs more RAM, it'll get rid of activities that are directly accessible but aren't currently visible, such as the launcher, the activity you'll go back to when you press back (maybe even in the same app as the activity that's running), or the greyed-out activity that's partly visible behind a dialog. This way, even if you have no free RAM, Android can free up quite a lot of RAM for the foreground activity: all the RAM on the device, except that needed by Android itself. I suggest to work out the best setting using trial and error. Without more knowledge of the app, I can't predict the effect of having the setting too low: perhaps the AI will make worse moves, or take longer to decide. If the setting is too high, you'll notice that when you leave the chess game you have to wait for the previous app to launch: this is particularly noticeable when it's the launcher, and you get a spinning progress indicator instead of the list of apps. If this were one of my apps, I'd consider this a bug. It's bad form to give the user a setting with no way to know what value to set. The app has more information about how much RAM the device has and can make available than you do: it should decide itself. | How much RAM should I allow an app to use, and how much should I always leave free? | android |
I just upgraded my cell phone to android 4.1.2. And I was shocked to see that there is no import/export option in my messages app. While in 4.1.1 there was the option of import/export. My search for solution: I have tried many other apps for messages too, they all lack the import/export feature. I then tried a new ROM of same version, 4.1.2! But again same results. My Question: Is there a ROM issue, or 4.1.2 does not allow this feature to import/export? My cellphone: I am using Qmobile A8.

I have a Huawei U8850 running Android 2.3.7 and want to manage my text messages more efficiently. At the moment the only delete options I can see are to delete all thread or the current thread. However, what I want to be able to do is delete individual text messages (both received and sent). The conversation with my wife (say) will include messages that are just acknowledgements of other messages being received or ones that are no longer relevant (shopping lists, say) and I would like to get rid of those, but keep the more important messages (at least for the time being). Is there any way to do this or am I stuck with either keeping the entire conversation or deleting it all? | All you have to do is press and hold the text message you want to delete.

I'm on a google nexus 4 (up to date, non-rooted) and I'm using gmail and google contacts for my contact/messaging needs. Additionally I'm pulling contacts from facebook, linkedIn, xing (German linkedIn clone) and google plus. Is there an easy way to merge contact info from other networks into the gmail contact when joining/linking contacts from gmail and other networks like facebook and linkedIn? I wouldn't mind using a third party app to do the footwork (joining, unduping, etc.) but I'd like to keep and update the data in my gmail contact list as I am using this list half of the time on my desktop. I don't mind using another contacts app for viewing/browsing and calling/texting my contacts but I don't want to depend on one forever and I don't want to redo everything again and again everytime I switch my phone and/or contacts app I know that Smartr and Rapportive (Desktop only) can do a lot of association stuff but in the end all the data that happens in Smartr stays in Smartr. Things I'd like to have: Data Contact Name Picture (assigned by me, default g+ with facebook or linkedIn as fallback) Nickname basic gmail stuff, multiple numbers, mails, addresses, birthday, other dates, urls other network profiles as "profile URLs" or sound "other URLs" Functionality easy linking/joining and un-duping data storage in gmail contacts as fas as possible compatibility with other apps like smartr or rapportive | KADlancer - check out http://www.fullcontact.com . (Full disclosure: I work for them, so I'm a bit biased. But the issues you mentioned are exactly the issues we're trying to solve). We currently have a web app in private beta that pulls in contacts from various Google Contacts/Gmail sources, as well as Facebook, Foursquare, LinkedIn, Twitter, etc. It then adds social profile data to each, normalizes & de-dupes them, and syncs them back in real-time. Within the next month we plan to roll out our public beta, which will support the linking of all of the above sources - meaning you can unify contacts across all your social networks/Google accounts and have all your contacts in one place, automatically up-to-date. Because we offer two-way sync in real-time, changes made in Google Contacts sync to FullContact, and vice-versa - meaning that your data is your data, and stays where you want it (no walled gardens). Again, I work for them, so you'd probably be right to take what I'm saying with a grain of salt. But based on what you posted, it looks like the FullContact Address Book will do almost everything you're looking to do (with the possible exception of Xing, which is currently not supported, but on the roadmap). I'm not aware of any other app out there that does quite what we do, save Smartr - which it sounds like you've already tried.

Is there a list of which kernel version comes in each Android AOSP version?

Long story short, my phone messed up and it's stuck in a bootloop. The phone in question is a Coolpad 7560U, also known as Orange Nivo, running Android 4.1.2 Jelly Bean. Data and cache wiping do not fix the bootloop. USB jigs are not a valid method either. The usual means of connecting to it using adb or fastboot don't work anymore -- neither will detect the phone in any way. I have tried all of the power on button combinations. All I can manage is to get into the stock recovery mode (the same one the bootloop passes through) and a QPST "通讯中 Secboot" Download mode. I am connecting the phone to my Windows 8 x86 PC through an USB cable. For a certain timespan during the boot loop, the following devices show up in Device Manager, all at once: 3 storage devices : One of them is a CD-ROM drive and the other two are generic removables - None of them are accessible, returning the prompt "Please insert a disk into drive *:". 4 other devices: Under "Ports (COM & LPT)" Coolpad Android AT USB VCOM (COM7) Coolpad Android Diagnostics USB VCOM (COM10) Coolpad Android NMEA USB VCOM (COM9) Under "Modems" Coolpad Mobile USB Modem Phone These four seem like my only means of landing a connection to the phone. Update: According to Alex P.'s answer, I can confirm that the "Secboot" mode puts the phone into a QPST Download mode. The 4 serial port devices do indeed allow for access to the phone through Qualcomm's QPST software suite, and probably impossible to push adb or fastboot commands through. | The serial interface you see is a Qualcomm DIAG interface. It has nothing to do with ADB/fastboot. It can be used to recover the phone though by flashing the proper bootloader. You will need to use Qualcomm tools like QPST and find the proper flashing image in QPST format. | ADB/fastboot over Serial/COM ports? | android |
I received a 7" tablet as a "gift" when I attended a presentation recently. I'd like to find out some specs about it (processor details, who the manufacturer is in case I need support, etc.). I hope someone can help point me in the right direction... The device came in a white and blue box that said "Android" and "Tablet PC" on it. There is no mention of any manufacturer, so my guess is I got an extremely cheap Chinese tablet. The instructions seem to indicate so...the English in it is horrible. Based on the "About tablet" section in Settings, it seems to be running stock Android 4.0.4 and its model number is "TWD_MID". I did some searches but couldn't find any conclusive manufacturer/specs.

Forgive me if this is already asked, but I couldn't find it anywhere. (Most results involved 1 device and moving data between 2 sd cards. I have two devices and I want to move all data off the sd card to the first device so I can move the sd card to the second device.) I've upgraded devices (HTC Thunderbolt to Samsung Galaxy Note II) and would like to remove my SD card from the Thunderbolt and use it in the Note II. To get a clean start, I will format the sd card before placing it in the Note, and I know how to do this. I want to keep my Thunderbolt and use it as a "poor man's tablet". It's already removed from the cell service and I'll just use it on the home WiFi messing around with some odd projects. I've already uninstalled a bunch of apps, and moved any remaining ones from the sd card back onto the Tablet. What I don't know is how to protect the apps that remain from getting damaged when I separate them from the files they've been storing on the sd card. For example, there's a lot stored in: /sdcard/Android/data/ (such as Google Maps and Swiftkey) /sdcard/data/ /sdcard/.android_secure/ How do I protect the apps on the Thunderbolt from being harmed from permanently removing the sd card? Do I have to clear all their data, or uninstall/reinstall them after removing the card? | As Izzy said in the comments really your best option is to just buy a new card. They are super cheap especially if you buy online. I just looked on Amazon and the cheapest 16 GB SD card I could fine was just over $12.00 US. I'm sure you can go to your local electronics store and pick one up for around $20.00 US if you don't want to deal with buying online and shipping and whatnot. But, if you are stingy (most of us are, lets be honest!), make sure you have migrated all of your apps back to internal storage with AppMgr III . Once this is done you can shutdown the phone and remove the SD card. If you want you can create a backup of your SD card just in case you need the data on it in the future. You can just copy and paste all of the files into a folder and then compress it, or you can create a disk image of the drive, whatever is more convenient to you. Then turn on your old device with the card NOT inside of it. Go through all of your downloaded apps and see if any of them were relying on data on the card. Once you find the apps that need the SD card you can then choose to uninstall and reinstall them, or see if you can transfer the files off of the SD card and then back onto the device and then point the app to the folder. It might take a little bit of screwing around, but perhaps the feeling of having extra cash in your wallet will overcome the frustration of dealing with data migration. Good luck! | How can I (permanently) remove an sd card without harming apps on the device | android |
I bought an Android PC from Amazon and found it booted Linux then booted Android. I mean literally booted Linux (penguins splash), then booted Android (Android splash). I contacted the vendor asking this particular question, and he stated: The mini PC has the Linux bootup first as Android runs on top of Linux I have tried googling and searching Super User for an answer, but have so far found nothing. I know Android uses the Linux kernel to some extent, but is that statement correct? Is this common for an android device? If this is a false statement, should I be worried about 3rd party applications running on the Linux OS at boot? Device Information: Android 4.2 Jelly Bean, RK3188 Quad-core 1.6GHz CPU Cortex-A9 (28nm), 2G DDR3 RAM / 8G Flash stackexchange-url ("Link to Amazon"), and supplier . | Android runs the Linux Kernel for the core system and it can be (and is) optimized for various platforms (compiled for ARM, x86, x64, PPC, etc). Here is a fantastic graphic to demonstrate this for you: Source: stackexchange-url ("Post on Unix.SE") Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model. The kernel also acts as an abstraction layer between the hardware and the rest of the software stack. Source: http://developer.android.com/guide/basics/what-is-android.html And my comment on your second sentence is that Linux Kernel is not meant for only desktop operating systems. Its use cases vary from Desktop OS to Servers, mainframes and supercomputers to Embedded Devices. Linux is a widely ported operating system kernel. Due to its low cost and ease of customization, the Linux kernel is used on a highly diverse range of computer architectures: in the hand-held devices and the mainframe Systems, in devices ranging from mobile phones to supercomputers. On the other note: Palm (later acquired by HP) use Linux-derived operating system, webOS, which is used into its line of Palm Pre smartphones. Several network firewalls and routers from makers such as Cisco/Linksys use customized linux kernel. There are tons of devices out there which are using embedded linux. | Android runs ON Linux? | android |

Why does Google Play Music and other music apps display album artwork with such terrible quality? This occurs even when high resolution images are embed into the audio files. How can we fix this? | There is a solution, but unfortunately it is a bit tedious. This issue occurs because Android caches the album art at a low resolution. It also generates file names for the thumbnails in a weird manner (apparently by the value of the system clock the first time the album appears). This means that the fix will be manual unless you employ some computer vision software. Navigate to <code> Internal Storage\Android\data\com.android.providers.media </code> and copy the <code> albumthumbs </code> folder to some local directory. You'll see files such as <code> 1345139729376 </code> , <code> 1345139731350 </code> , etc in <code> albumthumbs </code> . These files have no extension but are actually just jpegs. You can just edit these files if your image editing software supports it, but we could add <code> .jpg </code> to make it easier. In Windows this could be done via the command-line with <code> ren * *.jpg </code> . Now if you're on Windows you'll probably see image thumbnails instead of the generic file icon and it will be easy to edit the images. I'm sorry if you have a lot of albums, but since the file names are as good as random we need to actually look at each image and replace it with its high resolution counterpart. If you changed the file extension we can change it all back with <code> ren * *. </code> (note the period at the end). We can then paste our modified album art back into the original <code> albumthumbs </code> folder on the device. The result: | Low resolution album artwork? | android |
The title sounds misleading... There exists a shortcut under the settings shortcut widget that points to notifications. In this I can see all the notifications that my phone had (even after clearing it in the pulldown notification tray). I have 2 questions: a) where is it actually located in the settings (I have been looking for it for a while) b) how do I clear this...there seems to be no option (do I reboot?) Here are the screenshots that may help clarify: | There's no way to get at this activity other than through a settings shortcut. The code for it can be found here on Github , and if you search the repository for the <code> NotificationStation </code> class you'll find all the entry points for it: in this case, only the shortcut intent filter in the manifest. If you examine the code you'll also see there's no way to remove old notifications from the list: as you can see in the screenshot, the greyed-out notifications are those you've dismissed from the 'normal' notification tray. However, this class is mainly intended as a demo. Android 4.3 adds support for any application (with the appropriate permission) to access and display the list of notifications. For example, a third-party launcher might want to show them, an app might want to show all notifications in a pop-up window iOS-style, a live wallpaper or daydream could respond to them graphically, or a utility might analyse your phone use from the notifications (something like Tasker could trigger actions based on notifications appearing or being dismissed). Because this is a new feature, and 4.3 isn't on many devices yet, it'll be a while before third-party developers invest the time needed to offer these features, but you won't have to wait long. | How to get to notifications in settings? | android |
