Vivo released the APEX concept mobile phone at the beginning of the year, and then officially released the vivo X21 screen fingerprint mobile phone on March 19. The latter is the first product of a large domestic factory that simultaneously adopts the offline fingerprint technology and a special-shaped full screen. Just like the X20 last year was the first mobile phone equipped with a full screen, Vivo's advantages in product decision-making and supply chain were quickly transformed into sales.

According to the big mobile phone retail data of Dixintong in March, the vivo X21 quickly became the second best selling item after the X20 when it was launched a week ago, and surpassed Huawei Mate 10 to win the third place in the price range of 3000-3999 yuan. It is the product with the highest sales volume in many sub categories of JD's "full screen mobile phone, camera mobile phone, and price range of 2500-4000 yuan".

Black gold, ruby red and diamond black

One month after the official release of X21, vivo released a new black gold screen fingerprint version of vivo X21 on April 19. We Love to play computer games We also got this machine ahead of time. It's quick to see it now.  

The vivo X21 black gold screen fingerprint version also maintains the blue and black gradient color packaging, and the accessories are still pins, instructions, headphones, mirco USB data cables, dual engine flash charging heads, and protective cases made of mixed materials. The black gold version and ruby red version are delivered with frosted black silicone borders, while the black version is a fully transparent mobile phone case.

The front of the vivo X21 black gold screen fingerprint version is a 19:9 ultra narrow U-slot OLED full screen. On both sides of the receiver are hidden infrared fill lights (for face recognition fill light), light/distance sensors and front camera, which support 1024 feature dimensions of 3D face unlocking. In addition to the appearance, the new profiled full screen is actually more like the original 16:9 screen with two additional small auxiliary screens.

The biggest feature of X21, in addition to Liu Haiping, is its off screen fingerprint technology. Unlike the X20 Plus, which uses Xinsi's unified solution, the X21 uses Xinsi's solution and the domestic Huiding's solution at the same time, both of which are very similar in recognition rate and speed. The fingerprint sensor is added under the OLED screen to identify with an optical scheme.

Vivo X21 black gold screen fingerprint version The back is 3D micro arc glass, and the coating underneath will vary in color depth and texture according to different light angles. The camera protection ring and logo of the black gold version have been changed to gold.

In fact, the biggest change of the vivo X21 black gold screen fingerprint version is the design of the side violin line. The ordinary black gold version generally uses the gold middle frame design, while the vivo X21 black gold screen fingerprint version uses the original coated black metal middle frame with four gold edge grooves running through the entire metal middle frame. The effect is much more low-key and restrained, with a little business style.

These four grooves have brought about far greater changes in the feel than expected. The new machine seems to have its own anti-skid groove. Personally, I prefer the ordinary version in the feel, and the latter is better managed. The black gold version is a small price for low-key shine.

In configuration, it is Snapdragon 660 AIE+6GB memory, dual pixel full pixel dual core focusing camera with 24 million light-sensitive units. Do not know which version is more to your taste?
