    Hi folks,

    Today when I put a new cover on my 9 pro, OS 11.2.8.8.LE15BA, it rebooted. No problem their.
    But, yes there is one, now the fingerprint scanner will not accept my fingerprint anymore.
    Just in case, did another reboot and I have even registered my fingerprint again.
    The one thing I do did a few days back was install a glass screenprotector. But after I installed it the fingerprint scanner still worked fine. So not thinking that will be the issue.

    Any help.tricks and or tips are very welcome.

    Can you please remove the fingerprints again, clear cache in recovery and add them again?

    Can you test it in safe mode?
    Do you have another screen protector?

    Weird thing is that it does add the fingerprints. No problem there. Just not able to unlock the phone

    Same thing... will not unlock my phone in safe mode either.
    And no I don't have any other screen protector. But can always buy one.

    Did that and none of the apps that use my fingerprint can use it anymore. Crap... this is getting bad now.
    Some apps doesn't see the fingerprint and some go crazy and give an error that I have tried to many time but that is before I even touch the screen.

    Did an other reboot and now I have lost one home screen and the google news feed when swiping from left to right...\


    Ok... restored all that... Still no working fingerprint scanner, anywhere.

    Now it says, to many attempts and I have to give in my code. And that is without me even touching the screen when I try to unlock it

    Running a back up right now. After that I will reset the phone. Getting nerveus here, just a bit.

    It is allways the same after each Update and/or reboot. Starts working again after some time/days.
    Dont waste too much time trying to solve it...
    Nothing of what is mentioned here will work.
    You can search in the forum and will find many users with the same issue.
    I have the same as well
    and already reported the Bug.
    But i guess they have more important stuff to fix for this waste of money.
