on a few occasions, i'm trying to lock and everytime i press the lock button the phone locks then immediately lock screen comes up, then face unlcok again. in the end have to lock the phone with it facing somewhere else then trying to peep at the screen from the side.
might have to do with my casing.
after a while i feel no diff from fingerprinting. might as well disable it. more trouble than help.
if it allows me to activate face unlock without hands, e.g. by voice command before it scans my face, then that would be great. but alas u still have to press the lock button to wake the phone, might as well just tap the fingerprint sensor.
