How to calibrate Fingerprint Sensor

Hi,

i want to calibrate the Fingerprint sensor on my Samsung A51.

Resetting and so on does not effect anything.

So I bought the calibration tool for the calibration but ca not find any software to start the calibration process.

IS there any hint for that?

Answer this question I have this problem too

Is this a good question?

Why did it stop working? Was it damaged, replaced? Has the phone had parts replaced etc?
