Mobile phone introduction

Generally, the appearance of a mobile phone should include at least one LCD screen and a set of buttons (some touch-screen phones reduce buttons). In addition to typical telephone functions, modern mobile phones also include PDA, game machine, MP3, camera, recording, GPS and other functions.

The function of mobile phone is developing towards PDA. More precisely, there will be no PDA in the future, only mobile phones, which will contain all the functions of PDA. Due to the limitation of battery capacity and the development of analog modulation technology, such as huge antenna and integrated circuit, this mobile phone has a square appearance and can only be moved, but not portable.
