Vivo X20 Plus UD With Under Display Fingerprint Sensor Review

Vivo X20 Plus was released September last year, and truly, it was an incredible flagship smartphone. Powered by the Snapdragon processor and all, Vivo X20 Plus was a joy to behold. However, the under Display fingerprint sensor which was revealed by Vivo at CES2018 will be officially unveiled in the Vivo X20 Plus UD come January 25.

The Vivo X20 Plus UD’s under display fingerprint sensor was designed by Synaptics, and it makes use of the light emitted by the smartphone’s AMOLED panel to scan the user’s fingerprint sensor.

The rear contains only the dual camera, LED flash and Vivo logo unlike the additional fingerprint sensor present also at the rear in the Vivo X20 Plus.
