Some owners of Samsung phones reports that the scanner of their devices, which works fine before, has stopped recognizing their fingerprints. Thus they fail to access their Samsung phones. So, if you forget the backup password, you can access it by following the below solutions:

Fingerprint Scanner Not Working


  • Before the workarounds below, you can press the "Power" button for around 10s and let the Samsung Galaxy/Note reboot. Then try the fingerprint and see whether it works or not.
  • Clean the scanner with a clean handkerchief.
  • Take the case or the protective cover off.
  • Add the new fingerprints and disable the old one by going to "Settings" > "Lock screen and security" > "Fingerprints".

Workarounds: After it fails to recognize your fingerprint a few times, sign in with your Google account. However, if you have turned on 2-step verification, this might not work.
