iphone 11 ios 15.6 screen problem

My iPhone 11 worked well, didn't fall down or get wet. But after the 15.6 update, the touchscreen started working horribly. There are presses that I don't do. Or when scrolling the internet page the screen starts to go up and down by itself. The edges of the screen don't work well. Locking and unlocking the phone helps, but only for a short period. Then the problem reappears
