Fingerprints keep failing

(Topic created on: 20-08-2023 03:33 PM)
Hi all, since having a new genuine Samsung battery in my Note 20 5g recently, my fingerprint recognising keeps failing. After a few days of working use it stops recognising my prints and so unable to access certain apps I use fingerprint access. If I remove and reinstall a fingerprint again it works OK but a few days later boom, gone again. Really ticking me off now. Testing shows fp works fine but doesn't remember my print. Help plz... 😔

Hi @Pipster61 It generally helps to have a few fingers registered twice, could try turning Touch Sensitivity off and on again before registering. An idea to clear the cache of the Biometrics. Go to Settings-Apps, next to Your Apps tap the 3 lines and select option to show system Apps. Look for
Tap that and go to Storage-clear cache.

if still problems try clearing the cache partition which can sometimes sort this issue. Follow these steps:
1. Turn off the device.
2. Connect To Computer or plug in USB-C Headphones , Press and hold the Volume Up key and then press and hold the Power key
3. When the Android logo displays, release all three keys.
4. An 'Installing system update' message will show for 30 - 60 seconds before the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.

@Pipster61 did a Samsung Service Centre replace the battery ?

To add a Samsung Service Centre can take a look at the phone as long as no work has been carried out by a non authorised Samsung Repair Centre. 

If I can be of any further help then please don't hesitate. Take care.  😎
