Samsung phone is not recognizing fingerprints
Your phone's fingerprint sensor provides a convenient and secure way to unlock your phone, and keeps your personal information safe. If you are having trouble using your fingerprint sensor there are a few things to consider.

Check for common issues with fingerprint recognition on phones
Fingerprints may not be recognized when you are charging your device wirelessly.
-
Make sure you are using a Samsung screen protector.
- Some Galaxy phones come with a preinstalled screen protector that will work with the in-screen fingerprint sensor. If the in-screen fingerprint sensor isn't working, it's possible that another screen protector has been installed on top.
- An uncertified screen protector may interfere if it covers or touches the in-screen fingerprint sensors.
- If the screen protector was replaced with a non-Samsung-certified screen protector, you may need to register your fingerprints again.
-
Remove protective cases.
If a phone case covers or touches the fingerprint sensor, or prevents your finger from touching it, it can interfere with the sensor's operation.
-
Moisturize your hands.
No matter where the fingerprint sensor is located, the sensor may not work if your fingers are too dry or chapped. It may be helpful to moisturize your hands with hand lotion. But keep in mind the touch screen and fingerprint sensor may not recognize overly wet fingers.
-
Inspect the screen and fingerprint sensor for scratches and dirt.
- Scratches or dirt may cause recognition issues with the fingerprint sensor.
- The phone may not recognize fingerprints that are affected by wrinkles or scars. Fingers that are particularly small or slim may also not be recognized.
-
Move to a cooler or warmer environment.
The sensor may not work well if the phone is in an extremely hot or cold environment.
