Please keep your fingers and the surface of the phone clean when unlocking. When entering, please move your fingers and do not press the same position. Use official films as much as possible. Unofficial films such as anti-peep film and anti-blue light film will have a certain impact on fingerprint performance. You can try it after peeling off the film or use it with a face. If the fingerprint still does not improve after peeling off the film, please go to the after-sales service for fingerprint calibration.
