Galaxy S8 fingerprint scanner not sensing finger

JUMP TO SOLUTION

I have had my Galaxy S8 for only a few days now. I have been having this somewhat off-and-on problem where my finger sensor doesn't sense anything: notification gestures, or fingerprints. The last time this happened (besides just a moment ago) , I had to restart the phone to get it working again. (Currently, the sensor isn't working.) I haven't read anythin about this, so I am assuming it is actually a hardware-related thing, although it seems to me like a software issue (since it works okay sometimes, and seems to start working again (after having stopped) if I restart it). I would like some kind of solution to this, or at lead to have confirmation that it is not the hardware.

Restart the phone in safe mode :

Go to fingerprint and delete your old fingerprints:

Restart in safe mode again and re-enter fingerprint or fingerprints:

Restart again but in regular mode

Everything should work.

I can confirm similar experience...

 

1. Phone was sitting idle for over an hour unused.

2. Attempts to unlock with fingerprint sensor acted as though sensor was dead (no response by phone, either accept or the "double vibrate" reject).  I have multiple fingerprints registered and none were responsive.

3. Unlocked phone with second level pin

4. Attempted to open banking app with fingerprint.  Again no response by phone at all (it was like the sensor event is not event occuring).  Had to login with password.

5. Reboot phone.

6. Fingerprint sensor operation restored (normal function).

 

So it doesn't appear to be a hardware issue, I only rebooted the phone to restore operation.

Scanner isn't sensing my finger either.

Same issue. A reboot solves it. However, we shouldn't be forced to reboot to get this important function working.

Same thing, reboot solves it. But I agree that we shouldn't have to do this to get it to work again, especially with a phone this expensive.

Also same issue. 5 days in them stops working. Is the reset fix a soft or hard reset? Is there likely a sw patch coming?

Same issue here; I've had to reboot my phone twice now (had it for about two months) in order to get the fingerprint reader working again.

All you have todo is reboot it every 2 hours.

Having the exaxt same issue here as well.

Talk to support and they said should be software issue. For now reboot and will be fixed in the next update.
