[DIRTY SENSOR :-/ ] XA2+ 3.1 Fingerprint sensor has gone crazy! Phantom finger touches.

The fingerprint stopped working properly. When you open the lid of the device, a finger touch signal is emitted several times and prompts you to enter the pin code (I am not touching the sensor). Then I deleted all fingerprints and tried to add them again. When I try to add a new fingerprint, I have the initial recording of my fingerprint without a single touch, then the device waits until I touch the sensor for real, then it again adds a new phantom touch (without my participation), eventually, the added fingerprint will unlock the device automatically without a single touch. As soon as the screen goes out, the sensor operates independently and the device turns on. I've noticed before that my screen on the device lit up, but I didn't care about it, so now I realize that it was the fingerprint sensor that triggered it. At the moment, he's completely lost his mind.
that show me, when i try add new fingerprint, without any touches, first touch always make by device - automatically O_o
P.S. I tried using the CDS Tool and it shows me the Fingerprint test: PASS at a glance, i.e. the first time I run the test, it goes through the test on its own without touching it, the second time it is waiting for me to touch it.
maybe some body can tell me where i can view any logs of fingerprint scanner? why it always detect finger when it not touchet?
