S24 Ultra fingerprint reader being annoying

[DanAhmed]

Hello,

I am experiencing an issue with the fingerprint scanner on my device. It is no longer recognizing my thumb, even after I have registered a new fingerprint. The scanner works when used for biometric reading and writing, but it does not work when I try to unlock the device.

Can you please assist me in resolving this issue?

Thank you.

Do you have a screen protector on the phone?
Some screen protectors are not very compatible with in screen fingerprint sensors

I have a screen protector and have no issues using fingerprint myself.

Every so often your device will need a pin to be entered. Then it will accept your fingerprint again.

Have you tried registering your thumb print twice @DanAhmed 

You can also go into Biometrics and fingerprints to check if your thumb prints are being recognised at all.

There us a diagnostic tool found in your Samsung Members App. 

A Samsung Service Centre can assess your phone.

Fingerprints in biometrics are working fine. It'd just giving me a problem on my lockscreen

Same problem: in my packet the fingerprint sensor try read my leg and (my leg not registred  ) disabled itself. The accident touch protect is enabled, I tried, when I unlocked my phone the protection screen popped but when locked the screen the fingerprint sensor read even if the atp turned on.. Kinda annoying because my previous Samsung  galaxy S22 didn't do that.
