tokens: Effects of mobile phones Nowadays, the popularity of mobile phones has brought about a lot of convenience but at the meanwhile a variety of problems as well, such as social, medical and technical problems . However, I do not think these disadvantages will outweigh the advantages brought by cell phones . In this essay, I would like to analyze these three issues in order to support my viewpoint . First of all, almost everything that changed our lifestyle a lot will also cause some social problems . Mobile phones are not out of expectation . Speaking loudly on the phone in public areas, such as schools, libraries and hospitals appears to be very impolite and offensive . What is worse, some students utilize their cell phones as an effective cheating tools in examinations in which they can send and receive answers by texting each other . Nevertheless, it is not impossible to solve these problems, as long as some regulations and rules can be effectively implemented . It is also worth mentioning that some harmful effects on our health are lethal . It has been proved that overusing of the electronic devices including mobile phones could lead to higher possibility of suffering hearing loss and even cancers, although the further investigation are needed . Another debatable problem is about techniques . There is panic among people that their conversation can be intercepted by the third party . This possibility exists all the time . But a more efficient and reliable system can also be invented to guarantee the private information of users . Moreover, the mobile phone has become a dispensable multifunctional tools in people's daily life . Not only used for communication, but it also functions as an Internet browser, a music player, a personal organizer and so forth . In conclusion, nothing can be overused without side effects . The contribution of the mobile phone to our modern society is prominent and people's dependence on it is irreversible, although it has a number of problems that should be well handled .
