First, consider the functionmobile phoneThere is no fingerprint identifier, so it doesn't matter whether it is damaged or not. If it is a relatively new touch smart phone, most of them have fingerprint identifiers. If the fingerprint identifier can't be used normally, first shut down and restart the phone, or restore the phone to the factory settings, to determine whether it is caused by system failure,If the fingerprint identifier still cannot be used normally after this operation, it should be damaged. In this case, you can only go to the official after-sales service for detection, and then replace it with a new identifier.
