Question

A mobile phone, also known as a cell phone, is one that we can use to make telephone calls to anyone from a great distance via a radio link. Apart from telephony, modern smart mobile phones also support a number of other services including text messaging, internet access, gaming, photography, and many business applications. The first cell phone weighed about 2 kilograms and was demonstarted in 1973 by Dr. Martin Cooper and John F. Mitchell of Motorola. Ten years later, in 1983, the first model of cell phone went on sale to the public. By 2011, over six billion people, 87% of the world's population, used mobile networks. In spite of the many advantages a cell phone has, it also brings about several problems that users should be awave of. Mobile phone radiation is believed to be harmful to human health. Some recent studies have found an association between cell phone use and certain kinds of brain disease. Another serious problem can be privacy and tracking. Once users have the phone on, they can be interrupted in many ways, and they can also be tracked by location data.
