Recently, vivo officially announced the news of X21, and also announced the front appearance of the mobile phone. The vivo X21 uses the most popular "profiled full screen" at present, and from the perspective of promotional posters, it is very small than the iPhone X.

Interestingly, according to the promotional poster given by vivo, although the vivo X21 still retains its chin at the bottom of the fuselage, it is actually very narrow, which is not what the real machine will be like. And yesterday the vivo official also officially announced! Vivo X21 will be equipped with under screen fingerprint!

Compared with other mobile phone manufacturers' profiled full screen, vivo plus full screen is the most suitable configuration for fingerprint unlocking under the screen, which is a great advantage for other manufacturers. At present, the back fingerprint identification standard for full screen mobile phones has always been complained about by everyone.

In addition, vivo officially announced that the X21 will be equipped with a Qualcomm processor! Is it really necessary to counter attack this time?
