A blue phone can be beautiful with a light gray phone case.

I believe everyone cares about the color matching of mobile phones. No matter whether it is local gold, Deep Space Expo, China Red, etc., it can win people's attention. But this year, many mobile phone manufacturers have launched the color matching of mobile phones with the theme of blue, which makes people fascinated.

The X9 of vivo introduced the color scheme of Vibrant Blue this year, and on the basis of Vibrant Blue, it also added the customized version of NBA and customized version of Curry, which is a great boon for basketball fans and children's shoes who like Curry or are interested in Vibrant Blue. The matching of the shape and color of vivo can't help but make people shine.

Huawei Glory 9 hired Hugh as the spokesperson during the publicity. Personally, I prefer the color matching of this charming sea blue. The metal that has been sandblasted by light fog is carefully carved by 3D lithography, which makes the glass bloom with a more transparent new light color. The dazzling light reflected by the glass body in the light presents a unique temperament.

History of development:

If we trace back, we will find that the concept of mobile phone appeared as early as 193s, when Bell Laboratories, the largest communication company in the United States, started trial production. In 193, Bell Laboratories made the first so-called mobile telephone. However, due to its large size, researchers can only put it on the shelf in the laboratory, and people will gradually forget it.

in April, 1973, martin cooper, a well-known engineering technician from Motorola, invented the world's first mobile phone for civilian use. When Cooper makes the world's first mobile phone call, he can use any electromagnetic frequency band. In fact, the first generation of analog mobile phones is to distinguish different mobile phones of different users by different frequencies.

—GSM system, the second generation mobile phone, distinguishes users by extremely small time difference. Nowadays, the frequency resources are obviously insufficient, and the number of mobile phone users is growing rapidly in geometric series. As a result, the newer CDMA technology, which distinguishes different computers by different codes, came into being.
