Ultrasonic fingerprint on Galaxy S10

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 safe and secure, and the Galaxy S10 series and Galaxy Fold have improved recognition to unlock your phone even faster than before. However, depending on which type of phone you have, the fingerprint scanner may be a little different.

Use fingerprint security on Galaxy S10e and Galaxy Fold

Note: You need to have a lock screen set up to add your fingerprint.

If you have a Galaxy S10e or Galaxy Fold, the fingerprint sensor isn’t located on the back or front of the phone. On the S10e, it’s actually located on the Power key itself, and on the Galaxy Fold it's on the Bixby key (directly underneath the Power key), making it easier than ever to quickly unlock your phone. Follow these steps to add a fingerprint and start using the fingerprint sensor.

From Settings, search for and select Fingerprints. Tap Fingerprints, and enter your security credentials. Then, follow the on-screen instructions to add your fingerprint. When you’re finished, you can tap Add to add another one, or tap Done. Next, make sure the Fingerprint unlock feature is turned on; tap the switch if needed.

Now you will be able to unlock your phone with just your finger. On the S10e, simply tap the Power key with the finger you used for set up, and your phone will automatically unlock. And on Galaxy Fold, you can either tap the Bixby key to unlock, or press Power and then tap the Bixby key.

Scan your fingerprint displayed on phone

Note: Pressing and holding the Bixby key will unlock the phone and launch Bixby.

Use fingerprint security on Galaxy S10, S10+, and S10 5G

Note: You need to have a lock screen set up to add your fingerprint.

On the other hand, Galaxy S10, S10+, and S10 5G don’t have a physical button like other phones. The fingerprint scanner is actually inside the phone’s screen, where the Home key is located. Cool, right? Here’s how to set it up:

From Settings, search for and select Fingerprints. Tap Fingerprints and enter your security credentials. Then, follow the on-screen instructions to add your fingerprint. When you’re finished, you can tap Add to add another one, or tap Done. Next, make sure the Fingerprint unlock feature is turned on; tap the switch if needed.

To unlock your phone, tap the screen or press the Power button. Then, place your finger you used during setup on the fingerprint icon. The phone will automatically unlock if it recognizes your fingerprint.

Remove a fingerprint from your phone

Although their fingerprint sensors are in different places, removing a fingerprint is exactly the same on Galaxy S10e, S10, S10+, S10 5G and Galaxy Fold.

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