The mobile phone was first named in 1973 by Martin Cooper who worked in Motorola. In 1983, Motorola released its first commercial mobile phone named "DynaTAC 8000x". It was 3995 dollars, and it was just an analog voice. Also, it was 794 grams and too big to carry. It needed eight hours charging and four hours of continuous waiting. However, it just could call 30 minutes. In 1989, Motorola developed a new phone again. It was named "MicroTAC". It had a flip structure, not like DynaTAC 8000x's bar structure. Its keypad had a cover, and it was 384 grams. Its price was 2945 dollars. At this point, most people did not use a mobile phone, and they used beepers.

Beeper was popular until Motorola's competitor appeared in 1993. It was IBM that made Simon. Simon was not considered as a smartphone at that time, but it was actually the first smartphone because of its touch screen which was not operated by hands but by a stylus pen. It was 0.5 kilograms and 23 centimeters. It was not that small, but people used it because it had many functions such as alarm, memo, schedule, and calculator. After nine years, Nokia 6650 was made by Nokia. It was the first 3G phone. It had a color display, digital camera, and it could take a short video. It was compatible with 2G because people at that time were unfamiliar with 3G. The 4G phone was first developed by Samsung. It was the first-ever 4G phone. It had a 3.3 inches display, and it was up to ten times faster than 3G. Also, it had functions such as Bluetooth and wi-fi. Lastly, the latest phone as of 2019 is Samsung's foldable phone. As it is being named with such, It is foldable. It has a 185.1 mm dynamic display and 512 GB storage space. However, its concern is about breaking caused by too much folding.
