Vivo X20 Play UD in-display fingerprint scanner secrets revealed

A long time coming, Synaptics finally launched late last year the first ever commercial in-display fingerprint sensor. Jumping immediately on the opportunity to be different, Vivo equipped its new X20 Play UD with the never before seen feature. JerryRigEverything demonstrated how users didn’t have to worry about scratches on the display but had to be extra careful not to break the screen. But since that was broken anyway, the YouTube channel’s Zack Nelson got to work in tearing down the phone to reveal the sensor’s secrets.
