In the past decade, mobile phone use has increased drastically. Funnily, in 2011, more people owned phones in the world more than toothbrushes. In 2018, there were approximately 3.7 billion mobile phone users across the globe. The number is projected to increase to 4.6 billion by the end of 2019. As opposed to the past, when a phone was just a phone -a communication device- today, things are different. A phone has become a fundamental part of life used for communication, entertainment, information, and guidance.
