To troubleshoot a phone that is not recognizing your fingerprint, try the following steps:

1. Ensure that your finger is clean and dry before attempting to use Fingerprint Reader.


2. Confirm that the Reader is not blocked by dirt, dust, lint, or oil by gently brushing the area with a soft-bristled brush.


3. Open the Settings and locate the Fingerprint Reader option. Make sure it is enabled.


4. Go through the steps to add a fingerprint correctly. Make sure to place your finger in the same position and angle as you did when you initially set up the Reader.


5. If the Reader is still not recognizing your fingerprint, try deleting the existing fingerprint and resetting it.
