As a evidenced in this special section, mobile phone technologies integrate functions that broadly include communication, information , and computation. High-quality cameras and video capabilities expand daily uses for personal and business use. Mobile phone include many other functions like GPS, web surfing, gaming, sensors, daily planner, calculators, flashlights, and Internet connects for social media usage and studies related things have enables people to rely on just one critical device rather than several. Overall - I can say that more usage of mobile phones is causing to many diseases like brain tumors , disturbed sleep , glioma , acoustic neuroma , cognition , headache , behavioral problems , physiological addiction , cancer , and neurological disease so, specially kids and senior citizens should not use mobile phone for social media and all the extra stuffs but they can use it for the studies so they won't harm their body by using mobile phones.
