How to fix OP6T Fingerprint Scanner Not Working Sometimes?
Well, it depends on what "not working" means
I believe that this is more due to an hardware issue since the scanner is actually embedded into the screen.
Most obvious fix is to update your firmware otherwise,
I found that "lightly" & firmly applying your finger onto the screen fingerprint sensor when first adding a new fingerprint helps & solved most of my issues in regards to incorrect fingerprint recognition.
When you firmly press the fingerprint - it reads the whole fingerprint as absolute recognition instead of partial areas of your fingerprint, which is why lightly applying fingerprints helps.
Let me know if this helps you too
If it says "too many attemps. Sensor disabled" means that you should try another way, with a pin, password or pattern.
Thanks for your help - help is always welcome however, they're asking about "solutions/how to fix fingerprint recognition issues" not how to gain access after many failed attempts.
That's the problem when there's not enough information. Specific solutions only come to specific problems. Let's hope the OP tells us better what's her problem.
She specifically stated what she wanted if you look over the post again
I won't argue with you, as we're both trying to help. But "sometimes" may be:
When it's dark
When it's lit
When it's wet
When it's dirty
When it's with a different protector
When the sensor had rubbed against the skin for too many read attempts
When the firmware is old
So, "sometimes" is not enough information...
I have found the scanner doesn't work as well as the one on my older phone. I just have to remember to wait a bit longer for it to be recognized. I've also found if my hands are wet or extremely dry, my prints often aren't recognized, and forget it if I've been eating chicken and haven't completely washed my hands. You can also adjust the number of attempts in the settings before requiring another method. I did that myself, but I can't recall off the top of my head how I did it. Just look around the settings.
PLEASE, please add finger swipe to fingerprint scanner to bring down shade and check notifications. This feature is missing and is has been available on most Android phones since 2016!!!.
