My Samsung smartphone is not recognizing fingerprints. How do I fix it?
- If the blue light filter is being used, the filter may turn off in certain situations that require fingerprint recognition. The filter does this to improve the fingerprint recognition rate.
- Available settings and screens may vary by a wireless service provider, software version, or device.
- We recommend registering your fingerprint in a position that feels comfortable for your finger to ensure that the fingerprint being read is identical to the one registered on the device. When re-registering your fingerprint, start at the center of the sensor and move toward the top & bottom, left & right.
Adding additional fingerprints
As a preventative measure, we also recommend registering multiple fingerprints onto your device in case your fingerprint gets damaged due to a finger injury or otherwise. You can add up to four different fingerprints. To do so, go to "Settings," then "Biometrics and Security," and then "Fingerprints." Enter your secure screen lock credentials. Select "Add fingerprint." Use the on-screen prompts to add the fingerprint and then tap "Done."
- If the screen protector is dirty or scratched, please replace it with a new one. We also recommend that you register your fingerprint again for better recognition after replacing the protective film.
- Ensure that both your fingers and the fingerprint sensor area, located at the bottom center of the screen, are clean and dry.
- Using a screen protector that is either thick, made of glass or silicone, or patterned, you may not be able to register or scan your fingerprints properly.
- Samsung cannot guarantee compatibility with third-party products, as the thickness and structure of protective films or screen protectors may affect the performance of the fingerprint sensor.
- Sensors may be positioned differently depending on the device. The potential issues described above only apply to in-display sensors.
