Clear wipe cache partition in recovery mode .

If possible factory reset the phone once bro it may solve most of the problems ..
Orelse go to service center

Done with cache wipe and reset.. got no luck. Nothing worked

After reseting enable both security on setting and try bro

U can add 3 fingerprints
Try to add same finger on 3 fingerprints slot
So u will get more speed on fingerprint unlocking ..

Anyway in my case inputting 3 fingerprint improved the reading speed..
