I replaced the damaged screen with a new one (2 times, ordered from aliexpress from two different sellers) and the touch screen goes dead state after the screen was off and on. The situation is the same with both of the screens Everything works fine till the screen is active, but after it goes off and after that on, only the physical buttons work. I tried to downgrade the firmware (from 7.1.1.0g to 7.0.1.0g), but the situation is the same, the touch function works till only the first screen off action. Is there any hint, tip, solution for this problem? I think it is a hardware related problem, but very strange for me.
