Re-register Fingerprint
Note: If you registered your fingerprint with the front cover on, re-register with the cover removed. If a front cover/protective film with a protrusion pattern such as a silicone case/thick front protective film is used, some protrusion patterns may be recognized as fingerprints and the screen may unlock.
-
Re-register Fingerprint.
- Please re-register your fingerprint when the skin on your finger is no longer dry. Your finger can dry out even if it is briefly exposed to outdoor winter weather.
- On the other end, if your fingerprint is registered while your finger is wet, the registered image may not be clear.
- Please dry any moisture off your finger and re-register.
-
Attach Protective Screen.
- Registering images including characteristics of the protective film may decrease the success rate of matching images.
- Please re-register your fingerprint while the protective film is attached.If you don’t know the location of the fingerprint sensor on AOD [always-on display], touch the screen once and you can see the fingerprint sensor location accurately. Please cover the area sufficiently for it to recognize your fingerprint
- It’s important to cover the entire green light area.
- The fingerprint location display settings can be changed in fingerprint settings Settings > Lock Screen & Security > Fingerprints > Icon effect .
Note: If you registered your fingerprint with the front cover on, re-register with the cover removed. If a front cover/protective film with a protrusion pattern such as a silicone case/thick front protective film is used, some protrusion patterns may be recognized as fingerprints and the screen may unlock.

Protective Screen Compatibility.
- Performance my be impacted if the film transparency is too low.
- Since the display takes a picture by reflecting light emitted by the photo, performance may degrade if the transparency is too low or if a film made of a material that disperses light is used
- Using film that is too thick will also cause extreme light scattering.
- If either of the above scenarios is true, please remove the protective film and re-register the fingerprint image and test unlocking the device with the film still removed.
-
Check for dust, water, or damage.
- Check for foreign matter or damage to the protective film at the location of the fingerprint sensor.
- In the case of foreign matter, wipe it clean, and if the protective film is damaged, replace the protective film and re-recognize your fingerprint.
- Using waterproof cases may interfere with fingerprint recognition.
- If a waterproof case + phone protective film is added together, recognition problems may occur depending on the thickness and material of the waterproof case.
Note: Recognition requires at least 1 second of time.
Other areas to check:
- If you have a wound on your finger or the surface isn’t smooth, register a different finger or wait until your finger is healed.
- Recognition requires at least 1 second of time.
- When recognizing, it is helpful to avoid strong direct sunlight as much as possible.
- The fingerprint sensor contains a function to learn fingerprint status during use so performance improves as you register and recognize your fingerprint.
- If you continue to recognize your fingerprint successfully but performance doesn’t improve and there’s a problem with recognition rate, please follow the instructions above and re-register your fingerprints evenly.
