Finger print sensor is giving error after update when I switched on my A50 after a week. Also speaker is producing rattling sound when playing any audio/video even at low volumes. Can feel the vibrations on the back of the phone. 
Did anyone else face these issues recently?

I tried factory reset also but no help. On selecting Finger print biometric in setting gives
"Fingerprint sensor isn't responding. 
An error has occurred with fingerprint sensor. If this message appears repeatedly, restart your device. "
I have tried all the things but problems still persists.
