The vivo X21 is equipped with the highly-anticipated under-display in-screen fingerprint technology, allowing users to unlock the phone without turning on the screen. The display consists of a 0.68 mm glass panel on top of an OLED glass layer and an OLED light-emitting unit, between which the fingerprint sensor is embedded. The vivo X21 is considered by many to be the perfect screen and fingerprint recognition solution. Devoid of additional physical attributes on the body of the phone such as slots or holes, the full-screen phone has an integrated appearance with navigation gesture capabilities and three sets of unlock effects.
The vivo X21 display has a special coating which does not affect fingerprints.
The vivo X21 uses a 6.28-inch Super AMOLED display with Full HD+ 2280 x 1080 resolution and 19:9 aspect ratio. It supports 99.5 percent of the DCI-P3 color gamut and 99.9 percent of the sRGB color gamut. The top of the front screen features an ultra-narrow U-groove design. The left and right bevels are 1.66 mm, and the upper and lower borders are 1.79 mm and 5 mm, respectively. The screen-to-body ratio is 90.3 percent.
The vivo X21 supports face unlock feature (branded as Face Wake), with 3D depth of focus. The vivo X21 can automatically detect 1,024 facial features and supports smart matching. It also uses infrared light to allow users to use face unlock at night.
During an event reminder notification, the system will determine whether the user is looking at the phone. If it detects a face, the phone will reduce the volume of the reminder.
The phone back cover employs Vivo’s Aurora Micro Arc design, with a 2.97 mm drop height on the left and right sides, and 0.57mm on the top and bottom sides.
The phone’s coating and screen color processing gives a unique glass luster effect. There are three styles, including Ruby Red, Aurora White, and Ice Drill Black. Each of these versions were inspired by the Myanmar wine valley, the Santa Claus Village in Rovaniemi in Lapland Finland, and the Reynisfjara Black Sand Beach in Vic Iceland, respectively.
As AI becomes a major trend in technology, many mobile platforms and smartphones are starting to support it. The vivo X21 is no exception.
