Fingerprint recognition can be affected by a number of conditions. Try each of the following to see if your device is having trouble recognising your fingerprint.
- Is your fingerprint sensor damaged? Check that the sensor isn't scratched or damaged.
- Are you using a screen protector? unoffical, scratched or dirty screen protectors may cause the fingerprint sensor to malfunction. Try removing or cleaning the screen protector.
- Are your fingers dry or damp? Fingers that are too wet or too dry may not be recognised. Let your fingers dry if they are wet or use a moisturiser if they are too dry.
- Are your fingertips bent? The fingerprint sensor works best when covered by your entire fingerprint.
- Are your fingertips scarred? Scar tissue and wrinkles can change your fingerprint. You may have to remove and then register your fingerprint again.
