Like I said, I blocked the light and tried different distances when calculating max value (got PS values between 6k and 20k). And non blocked for min values (about 200). Then I tried pressing calibrate button covered and not covered, but all say calibration failed. Did try to change order of calculating / calibration but all failed.

I see there was an update (noticed that UI of p-sensor changed and screen goes off now when calling ), it is working correctly for me now, thank you.
