Fingerprint scanner sometimes doesn't work at all

    xHawaiiToast, Jun 30, 2018 :
    Sometimes when I try to wake up my Oneplus 6 with the fingerprint scanner, absolutely nothing happens. I can put my finger on it as often as I want and the phone doesn't do anything. But when I press the power button and put my finger on the scanner everything works as intended. And after that the fingerprint scanner works just fine until the next time it doesn't do anything. The phone isn't even vibrating when that happens (it vibrates when you put your finger in the wrong position of the scanner or if another person try's to unlock the phone).

    try:
    1. turn off Smart Lock - all items
    2. remove fingerprints
    3. screen lock - none
    4. restart
    5. re-set pattern / pin - secure start-up - no thanks
    6. do not show notifications at all - not necessary
    7. add fingerprint ;)

    Hi, I've been experiencing the same issue. My guess it has something with android's deep sleep mode to do. But it is only a guess.

    Thank you for your quick reply, but I never had the smart lock option enabled and I already removed all fingerprints and added them back again. The problem is still present.

    If I turn off the pocket mode the phone will unlock itself in my pocket and my battery will thank me for that

    not smart Lock. pocket mode. I have checked, indeed, this is the reason.

    Hey, I don't think that this is the problem because it sometimes doesn't work immediately after I put my phone in sleep.

    Yeah but if you turn off the pocket mode, the phone will unlock itself in the pocket and this is far worse than the actual problem

    yesterday I noticed it. I had the fingerprint scanner bug about 30 secs after the screen goes off

    edit : so it's not related to the deep sleep

    Oh 30 seconds is really long. I had unlocked my phone always in less than 10 seconds.
