Sometimes my Galaxy S8/S8+ doesn’t recognize my fingerprint. What should I do?

Last Update date : 2017.04.07

When you scan your fingerprints on the device, be aware of the following conditions that may

affect the feature’s performance:

 

The fingerprint recognition sensor recognizes fingerprints. Ensure that the fingerprint recognition

   sensor is not scratched or  damaged by metal objects, such as coins, keys, and  necklaces.

 

• The screen protector supplied with the device may cause the fingerprint recognition sensor to

   malfunction. Remove the screen protector to improve fingerprint sensitivity.

 

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

 

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

 

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

 

• If you bend your finger or use a fingertip, the device may not recognize 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.

 

For best results, while registering, for entire enrollment please cover entire fingerprint recognition
