Finger print sensor is not working

[VigneshBabuMRJ]

Finger print sensor is not working on my M30s device suddenly. It was working fine and all of a sudden when i unlocked my device it is showing "Fingerprint sensor is not responding". It worked for sometime and stopped working and then when i started my mobile it worked for few minutes. Now it is not working.

Tried restarting, cleared cache partition, Cleared security app data, restarted to safe mode and tested, pressed *#0*# and did finger print test. It shows "Cannot found Data log!!"

Software updated done on June. No recent updates. Is there any m30s users facing same issue?

same with me. also I'm facing sequential auto-restarting problem since 1wk & now It's even not switching on. 😔

Did you update any application recently?

This is either software glitch or motherboard issue.. Visit service center for reflashing software or check with them if any hardware issue.

@ImSRV I visited. they said to submit the handset with whole in box accessories for 20-25 days and if the problem doesn't resolve then will provide me a new set.
can u say which type of documents they will give me after receiving my handset ? cause the engineer of service center bhve so rudely and didn't answer clearly my qs. I'm worrying to give the handset to them. 😔
