How to use the fingerprint scanner on the Galaxy S10

The Galaxy S10 and S10+ use an Ultrasonic Fingerprint Scanner that is embedded into the screen. This uses soundwaves to create an intricate 3D map of your fingerprint.

 

The Galaxy S10e uses an Electrostatic Fingerprint Scanner on the Power button. This uses an electrostatic charge to record a detailed image of your fingerprint.

2 Tap “Biometrics and security”.
3 Tap “Fingerprints”.
4 Enter your PIN, pattern or password. If you haven’t set one, you will be asked to register one first.
5 Place your finger on the sensor area (as indicated on the screen) and keep pressing it until your fingerprint is fully captured. The fingerprint image will be completely blue when the process is complete.
6 Then, to get a full scan, rotate your finger on the sensor to capture the edges of your fingerprint.
7 Once complete, tap “Done”.
8 It will then show as “Fingerprint 1” on the display.

Please note: The scanner may struggle to recognise your fingers if they are too wet or too dry, for example in very cold weather conditions. Ensure that the fingerprint sensor area is not scratched or damaged by metal objects such as coins, keys, pens and necklaces. Press the screen so that your fingertip spreads over the wide surface of the fingerprint recognition area.

Fingerprint recognition can be affected by a number of conditions. Try each of the following to see if your device is having trouble recognising your fingerprint. 

 

  • Are you using a different finger? Make sure that you use the same finger that you used to set up the lock.
  • Is your fingerprint sensor damaged? Check that the sensor isn't scratched or damaged.
  • Are you using a screen protector? unoffical, scratched or dirty screen protectors may cause the fingerprint sensor to malfunction. Try removing or cleaning the screen protector.
  • Are your fingers dry or damp? Fingers that are too wet or too dry may not be recognised. Let your fingers dry if they are wet or use a moisturiser if they are too dry.
  • Are your fingertips bent? The fingerprint sensor works best when covered by your entire fingerprint.
  • Are your fingertips scarred? Scar tissue and wrinkles can change your fingerprint. You may have to remove and then register your fingerprint again.
