If you are experiencing issues with the fingerprint recognition feature once you scan your fingerprints on the device, please be aware of the following conditions that may affect the feature's performance 

• The fingerprint recognition sensor recognises fingerprints. Ensure that the fingerprint recognition sensor is not scratched or damaged by metal objects, such as coins, keys, and necklaces.


• Covering the fingerprint recognition sensor with protective films, stickers, or other accessories may decrease the fingerprint recognition rate. If the fingerprint recognition sensor is initially covered with a protective film, remove it before using the fingerprint recognition sensor.


• Ensure that the fingerprint recognition sensor and your fingers are clean and dry.


• The device may not recognise fingerprints that are affected by wrinkles or scars.


• The device may not recognise fingerprints from small or thin fingers.


• If you bend your finger or use a fingertip, the device may not recognise your fingerprints. Make sure to cover the entire fingerprint recognition sensor with your finger.


• To improve recognition performance, register fingerprints of the hand used most often to perform tasks on the device.


• In dry environments, static electricity can build up in the device. Avoid using this feature in dry environments or before using the feature, discharge static electricity by touching a metal object.

Please note: The information above is designed to support not only the following models S8, S8+, Note8, S9, S9+ Note9, however may not aply to other models.
