How do I calibrate the optical fingerprint sensor Samsung Galaxy A70?

Hello,

I am trying to repair a Samsung Galaxy A70 with a previously replaced display.

After this replacement, the fingerprint sensor doesn't work. The sensor might be broken but I was trying to do a calibration to see if it is really the case.

I found this tutorial but the app doesn't work on my device (How to Calibrate an Optical Fingerprint Sensor)

I also found this video using the app, but I can't find where to open this calibration menu https://www.youtube.com/watch?v=wYyBPF35...

Here are the status of the sensor (see linked images)

On some A series Samsung phones the fingerprint sensor stops working completely after screen replacement. Don't think there's much you can do.
