1 year agoI’ve had my S21 U for over 2 years now, have a cheap screen protector on it, and anytime I have trouble unlocking, I warm up my thumb for a couple of seconds by rubbing it against my index finger.
As soon as I do that it works fine again.
This is for the about 5% of the time I have trouble. 95% of the time it works fine.
My wife never can get hers to work but I’m able to unlock hers fine with my print.
I think it’s really the person not the tech. Some people just always have trouble with capacitive touch devices not working well for them
Try the warming trick and see if that helps.
