What should I do to improve fingerprint recognition?

Last Update date : 2017.07.14

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

affect the feature’s performance:


  The Home key contains a fingerprint recognition sensor. Ensure that the Home key is not

    scratched or damaged by metal objects, such as coins, keys, and necklaces.

  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.

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

    to malfunction. Remove the screen protector to improve fingerprint sensitivity.

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

    your fingerprints.  Make sure to cover the entire Home key 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
