The mobile phone has become a very important device in our life today. It is not just used to call other people. It is used for texting messages, photos and videos and for chatting as well. In recent years, with smartphones, people can do a lot of more things, such as reading news, joining social media, and of course playing games. The first mobile phone call was made in 1973. The handle device used weighed 1.1 kg. Its talk time was just half an hour. Nowadays, however, mobile phones have become much smaller, and of course they allow us to talk much longer. Police records show that mobile phones have become “thieves’ favorite”. Maybe it is because they are easy to be hidden and some of them are very expensive. In 2012, half of the robberies in San Francisco were thefts of mobile phones.
