de0u does it work better if a delay is added before/between presses?
Thanks for the warning about the factory reset, I was indeed not planning on doing that.
For me it is not really a problem that I cannot use this function, I use the password most of the time, but I can imagine that it may be a real issue for others.
I tried applying the registration of the fingerprint with delays, but it still seems to crash regardless, but I will tey several other ways as well, like not doing anything for a while, (waiting on the fingerprint registration screen) to see what happens...
Edit: If I try doing it really rapidly, the crash seems to appear faster, like if it only triggers after several amount of presses.
