the S20Ultra finger print scanner is the worst of all phones i had so far, almost as bad as face recognition...guess typing the pin is still faster 😅
face recognition on Xiaomi MiNote 10 works almost each time, it requires less light too, on the HuaweiP40pro it actually never fails, only with a mask you can make it confused and it works 100% of the time, but the S20 Ultra....4 out of 10 times? on top of that you have to even look into the camera and almost get the 90 degree angle to the camera, else it may not unlock.
I'm not used to that, i'm used to pick up the hone and it's unlocked by the time i blink or before that.
i will just assume what you said was a sarcastic joke, bcoz with my settings i can not make it improve more.
the issue is a fingerprint scanner, which sits behind the screen, so increasing screen sensitivity will work for the screen only....and that is bcoz neither a resistive nor capacitive screen, can capture ultrasonic vibration, else you would use the screen as a microphone.
