Finger print sensor

My finger print sensor has stopped working..any ideas please? 

I have turned the phone on and off and still

If you've put a screen protector on your phone, then the finger scanner might go to pot.
It's about time Samsung caught up with Face ID from Apple.

I have the z fold 3. The scanner is on the side. It's bizzare, it just stopped out of no where

I've always found the fingerprint scanner on my Samsung Fold³ to work 100% @Ashley211 

Have you downloaded anything recently  ?

You could delete your current fingerprints and reset them back up.

Safe Mode may help > Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. 

Also clear your phone's System Cache Files Section > Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too.
