Many Samsung Galaxy smartphones are equipped with a fingerprint sensor, which is used to unlock the smartphone or unlock or open other sensitive functions.
If you have set up a fingerprint sensor and use it diligently, it can happen after a while that your finger is no longer recognized correctly or not recognized at all.
Usually there is no hardware problem, but an error with the software or the corresponding service app in Android.
For this reason, we would like to show you here exactly how to proceed if the fingerprint sensor does not work properly on a Samsung Galaxy with Android.
Fingerprint Sensor - Reset Services App
1. On the Samsung Galaxy, open the settings within the Android system
2. Navigate here to "Apps".
3. Touch the three-point symbol in the upper right corner and there in the context menu:
- "Show system applications".
4. Now search for "Fingerprint" in the list and select the corresponding app.
5. You will now see the app info. Open "Memory
6. Now select "Delete data".
7. You will then need to re-enter your fingerprint on the Samsung Galaxy.
If you now use the fingerprint scanner again to unlock the smartphone, this should work as usual.
If this does not help, you should run a Wipe Cache partition on your Samsung Galaxy to fix the problem. This is done as follows.
