What to do when Galaxy S5 cannot recognize fingerprint?

For best results, swipe your entire finger from base to tip across the home key to register your fingerprint properly. Do not bend your finger or use a fingertip during registeration as the device may not recognize your fingerprints.

Factors that will affect fingerprint recognization:

• Accessories such as key protector

• Moisture. Make sure both the screen and your fingertip are dry

• Avoid contact with metal objects such as coins, keys and necklaces which can scratch or damage the Home button that contain the fingerprint recognition sensor
