Occasionally there is dust and water droplets on the screen or the Home key can prevent proper fingerprint scanning, even if your device is waterproof. In such cases, it is better to clean the surface of the phone with a soft, damp cloth. Note that applying creams, gels and disinfectants to the hands can also interfere with the sensor.
Add a new fingerprint to the device
As you know, each person’s fingerprint is completely unique. But this does not mean that it can not be deformed. In fact, the fingerprints of people, especially those working in the technical and handicraft fields, are constantly changing. Therefore, resetting the fingerprint pattern can solve the sensor problem.
To do this, first go to the Settings section of the device and then click on the Security and Fingerprint options, respectively. Now re-add the fingerprint pattern to the device.
