I opened the phone and the display was ok and the touch also, the problem was in the connector of mainboard and the screen, it should be replaced, because after closing the phone the problem appeared as it was previously. Unfortunately my phone went to the garbage, because I was not interested in downloading the bond from China and waiting one month for the package. I bought the M5 Note instead from Poland.
