    Hi everyone one!
    I have a strange problem! When I reboot my OnePlus 9 Pro my under display fingerprint reader won't work.
    But after sometime I will work (maybe 30-40 minutes later)
    The facial recognition work and I can type my password to unlock it.
    Does someone else have this problem?
    Thanks.

    (I run the latest updates Oxygen OS 11.2.8.8.LE15AA)

    Welcome to op9...
    Same after every restart for me.
    For me it fixes it self after some time/days without any specific things to do.

    Search for "fingerprint" in the forum to find All the other posts. But i would not recommend doing any of the suggested methods trying to fix this. It's a waste of time.

    For the first time, immediately after rebooting?

    I think this is kinda security feature, not a bug. I always have to put a security code too after the reboot then fingerprint works.

    You can't unlock your phone using the fingerprint scanner or face unlock after a reboot for security purposes. You need to use the lockscreen passcode/pin/pattern for unlocking your phone immediately after a reboot. You can use fingerprint and face unlock afterwards.
    It's been like this on android since...forever.
