Additional Notes

Temporary solution for fingerprint disappearing on reboot / registration error

The file /data/system/users/0/fingerprint-settings.xml holds reference for each finger that's in the fingerprint database. This settings file is for some reason removed every time the phone is rebooted. The OS now no longer knows about any of the fingers, but they're there in the database. As such, if you try to register them again, the enrollment will fail. Deleting the fingerprint database file /data/system/users/0/fpdata/user.db and rebooting will allow you to set up fingerprints again, until you reboot. This is a temporary solution until the problem is solved.

The device can take up to 2 or more seconds to wake up on some occasions. This can be improved by using a custom kernel, such as ElectraBlue (Treble)

The build is pretty stable, but if you encounter any bugs, please upload a logcat to the telegram group P semi-GSI
