So if you type the password more than 3 times with like 10 seconds you cannot unlock device or do anything it unlocks but relocks straight away. However fingerprint scanner will still work. If you reboot you cannot use FP scanner and the bug persists you cannot get into the phone. Other devices have this problem.But what does the 'crash' have to do with it? That was just an attempt to solve fp sensor listening when it shouldn't be doing it...
BTW that patch didn't even fix what we were hoping for:
Edit: The bug occurred again I removed lockscreen data files and factory reset and it seems its no longer present so unless I get it again its a bug my end and I will get logs.
