Android 10 can't use finger unlock

android 10 can’t use finger unlock, when add fingerprint the app restart。

Thanks for the feedback!
To find faster the cause of this problem, could you please send us your log file?

Just verified, fingerprint can be activated using Android 10 in general. This must be a more specific problem but affects not all Android 10 phones. A log would be really helpful :slight_smile:

I have the same problem on Android 10, can’t activate unlocking with fingeprint.
I’ll try to paste a part of the log here since it seems that I cannot attach it as a textfile.
The problem occured after an update of android (from oxygen os 10 to 10.3, i guess) and it seems that the app didn’t have storage permission. however, giving it permission to the storage did not solve the Problem.

Thanks for the log. We need to do some research here.
Please stay tuned!

fixed it by disabling lock screen in Android security settings and activating it again.
problem seems to be in Android’s “keystore” (whatever that is…)
