Set up and use the fingerprint sensor on your Galaxy phone

No one in the world is quite like you, and no two fingerprints are exactly the same. That’s why fingerprint security on Galaxy phones is so dependable. However, using the fingerprint scanner may be a little different based on which type of phone you have.

Note: The following instructions apply to phones with Android 9.0 or higher. Available screens and settings may vary by wireless service provider, software version, and phone model.

Find the fingerprint scanner's location

Note: The A10e, A01, and A02 do not have fingerprint scanners.

Depending on which Galaxy phone you have, the fingerprint scanner may be in a different location. Make sure you know the location before you start registering your prints.

Phones with an in-display fingerprint reader:

  • S10, S10+, and S10 5G (Ultrasonic sensor)

  • Note10, Note10+, and Note10+ 5G (Ultrasonic sensor)

  • Note20 5G and Note20 Ultra 5G (Ultrasonic sensor)

  • S20 5G, S20+ 5G, and S20 Ultra 5G (Ultrasonic sensor)

  • S21 5G, S21+ 5G, and S21 Ultra 5G (Ultrasonic sensor)

  • A50, A51, A71, A42 5G, and A52 5G (Optical sensor)

Phones with a fingerprint reader on the back:

  • A11, A20, and A21

  • S8, S8+, S9, and S9+

  • Note8 and Note9



Other locations for the fingerprint scanner:

  • The Fold's and Z Fold2's scanners are located below the Side key.

  • S10e has the scanner on the Power key.

  • The Galaxy Z Flip's and Z Flip 5G’s scanners are located on the Side key.

  • The A12's and A32's scanners are located on the Side key.

Phones with a fingerprint scanner on the Home key:

  • S6 and S6 edge

  • S7 and S7 edge

Set up and use fingerprint security

It's time to set up fingerprint security and register your prints. The steps will be almost exactly the same, no matter what phone you have. The only difference will be where the fingerprint sensor is located.

  1. Navigate to Settings, then tap Biometrics and security, and then tap Fingerprints.

  2. Tap Continue. If you do not have a screen lock set up, you may be prompted to create one at this point.

  3. Use the on-screen prompts to register your fingerprint. When registering your fingerprint, make sure to fully cover the fingerprint sensor with your finger to prevent strong light from entering the fingerprint sensor. When you're finished, tap Done.

  4. Next, make sure that the switch next to Fingerprint unlock is turned on. 

    Note: If the fingerprint sensor on your device is located on the Side key or below the Side key, such as on the Z Fold2 and Z Flip 5G, you can disable the Fingerprint always on option to prevent accidental unlocks. 

  5. To unlock your phone using your finger, tap the screen or press the Power key or Side key. Then, place the registered finger on the fingerprint scanner, wherever it's located. The phone will automatically unlock if it recognizes your fingerprint.

Keep in mind that when your phone is restarted or if your phone has not been used for more than 24 hours, you’ll need to use your PIN, password, or pattern instead of your fingerprint.

Note: Some phones may come with a pre-installed plastic screen protector designed to work with the in-screen sensor. Installing another screen protector may affect fingerprint recognition.

Add additional fingerprints

If your family or friends occasionally use your phone, register additional fingerprints so they can unlock it too. You can add up to four different fingerprints.

From Settings, tap Biometrics and security, and then tap Fingerprints. Enter your secure screen lock credentials. Tap Add fingerprint. Use the on-screen prompts to add the fingerprint, and then tap Done.

Remove a fingerprint from your phone

Although their fingerprint sensors are in different places, removing a fingerprint is exactly the same on all phones with Android 9.0 or higher.

From Settings, tap Biometrics and security, and then tap Fingerprints. Next, enter your security credentials. Tap the fingerprint you want to delete (e.g., Fingerprint 1), and then tap Remove. Next, tap Remove again to confirm.

Rename or remove a fingerprint screen on a Galaxy phone

Note: Removing all registered fingerprints will turn off the Fingerprint unlock feature by default.

Trouble unlocking phone with fingerprint

If you are having trouble unlocking your phone because the fingerprint sensor isn't recognizing your prints, try entering your regular PIN, password, or pattern. If that still does not work, you can try remotely unlocking your phone using the Find My Mobile feature or another method.
