Use the finger print sensor on your Galaxy phone or Tablet

Follow these tips to help your fingerprint sensor work every time:

Step 1. Make sure you are covering the whole sensor with your finger, and hold the device the same way as when you set up the fingerprints.

Step 2. Make sure the scanner and your fingertip are clean and dry before scanning.

Step 3. Restart the phone or tablet and try using the fingerprint scanner again.

Step 4. Keep the device and apps up to date.

Step 5. Remove and re-add the fingerprints.

 If you are still having trouble unlocking your device because the fingerprint sensor isn't recognizing your prints, try entering your regular PIN, password, or pattern.

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

1. Navigate to Settings, then tap Security and privacy.

2. Tap Lock screen, and then tap Fingerprints.

3. Enter your lock screen credentials. If you do not have a screen lock set up, you may be prompted to set a secure screen lock (PIN, password, or pattern) at this point. When you're ready, follow the on-screen information.

4. Tap Continue on the Fingerprints screen, and then use the on-screen prompts to register your fingerprint. 

5. When registering your fingerprint, make sure to fully cover the fingerprint sensor with your finger to prevent strong light from entering the sensor. When you're finished, tap Done.

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