How Troubleshoot Fingerprint Scanner Issues:
Try all the following in the order given and one should solve your fingerprint scanner issue. You can also watch the video below to see exactly what to do
1.Clean your Fingerprint scanner: If oils, dirt or other foreign materials get on the Fingerprint sensor it can smudge the sensor and affect its ability to unlock your phone or recognize your fingerprint. I suggest you clean the sensor with a lint free cloth, cotton or some other similar material. You can also damp the material in Alcohol as well slightly before cleaning.
2. Your Phone has been on for too long/Overheating: If your phone has been on for weeks it will start to behave weird. It’s always a good idea to reboot once a week or every few days. If your device has been on for days reboot as this can cause the Fingerprint sensor to act oddly.
Similarly if your phone is overheating the fingerprint sensor may not function as it should. I suggest you power down the phone and allow it to cool before attempting to use normally again. The sensors should start functioning as normal when things cool down.
3.Your Fingers are Not making contact with the sensor properly: If your finger is partially or oddly placed on the sensor it may not be detecting your fingerprint correctly. Also Make sure to leave your finger long enough on the sensor so it can detect your fingerprint,if you remove it too fast then it wont be able to read it.
4.Clear Cache of the Fingerprint System App: To do this go to settings, then applications, Application manager, then all and look for Fingerprint and click on it. Next clear cache and force stop the app and finally reboot. When you are back up the scanner should work.
5.Delete and Re-enter your fingerprint:Go to settings, Lock screen and security,finally go to fingerprints and then finally delete and replace the fingerprints or add new ones. By re-scanning your fingerprints it may help in most cases to solve the problems you are having such as recognition by the phone.
6.Last Resort: If all else fails then backup your phone and its data and then do a reset or hard reset. This will delete all your data but may be the only way to get your Fingerprint scanner to work normally.
