I restarted my device but the problem is still same and the problem is intermediate and it occurs 10 to 15 minutes in standby mode when screen is off and you try to unlock using fingerprint directly without tap or turning on the display.

After installing 1 Dec security patch Fingerprint sensor not working properlyWhen screen is off (standby mode) fingerprint id became un-responsive after some time and you have to turn on the screen to use fingerprint id
