Out of a sudden the fingerprint sensor stopped working (both as a back button and unlocking the screen).
So now I can’t use the back button and I can’t unlock the screen with the fingerprint.
In Settings > Fingerprint and security, “Use to unlock screen” under ‘Fingerprint identification’ is disabled! And when I enable it it goes to the “Enter passcode” screen. I enter my passcode and then it says Place your finger… I place my finger on the sensor and nothing happens. It doesn’t detect it. So I hit Cancel and obviously the “Use to unlock screen” is still disabled.
It started happening yesterday (Flyme 220.127.116.11G), and today I upgraded to 18.104.22.168G and the problem persisted.
