How do I calibrate the optical fingerprint sensor Samsung Galaxy A70?
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 (Come calibrare un sensore ottico di impronte digitali)
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)
Thank you !
