How to set up the Fingerprint scanner

Last modified : Oct 17. 2019

Biometric security is a function that many Samsung mobile devices are starting to offer. Fingerprint recognition uses the unique characteristics of each fingerprint to enhance the security of your device. If you use your fingerprint as a screen lock method, your fingerprint cannot be used to unlock the screen for the first time after turning on the device, so you'll need to set and remember a back up PIN, Pattern or Password.


Click on the drop down menus below to learn how to setup the fingerprint scanner based on your Galaxy phone's Android OS Version.

Please Note: The location of the fingerprint scanner may differ according to which model you are using.

Fingerprint Troubleshooting:

  • Keep your skin and the fingerprint scanner dry when attempting to unlock your device - the scanner can't read if moisture is detected.
  • Your finger should cover the fingerprint scanner completely.
  • Make sure no case or cover is restricting access to the scanner.
  • Keep the fingerprint sensor free of dirt or debris. If the scanner gets dirty, wipe it gently with a soft dry cloth.
  • Scanning each finger at multiple angles will increase the fingerprint scanner accuracy.
  • Try removing your registered fingerprint and re-scan.


If your Fingerprint scanner is not recognising your fingerprints - unlock the device with your backup credentials and restart your phone.
