The under screen fingerprint scanner

In CES 2018, One of the phone manufacturer had unveiled a new smartphone technology that allow the users to unlock their phone by touching the screen. It is called under display fingerprint unlock . The feature could help to gives a clear phone design. The main scientific theory applied was the usage of ultrasonic soundwaves and image generating . However the feature could only applicable when the phone is turned on and won't work if the phone is in the sleep mode. Hope Nokia can consider this thing. Made it to unlock even the phone screen in turned off. We're not here to compete but hope such great feature could come to Nokia phones soon.
