    I set the phone for fingerprint to be active even with display off, so i can unlock my phone without lit my screen,
    Randomly, every 20-30 times maybe, fingerprint icon will not lit when i touch it. So i have to turn on display and after this i can unlock with fingerprint. After this again i can unlock my phone with fingerprint with display off, for another 20-30 times.

    Try resetting your fingerprint again then clear cache in recovery and see what happens
    Did you get Android 13 yet?

    Hi again. I try to turn off adaptive battery, no result same problem occur. No other power savings active, by my knowldge at least
    I try to reset figerprint by removing and add again. No result. But this not a problem of recognition, my sensor for fingerprint will not lit when i touch. I also perform a clear cahce in ecovery mode. Im on android 13, and maybe this problem comes with this update. The phone works fine for few months and suddendy this problem, cant say if this occur with android 13 update o r few days early on android 12
