If you check more closely you can open the app Note Go up, find the pen icon, and draw a line on the point you suspect is the touch dead. If you see that the line is broken at the other dead point, then that place is probably paralyzed.
There is another way you can test the touch by shutting down and restarting, when the apple emblem is white and around is black, look to see if there is any other color display such as blue, red, purple and yellow. no… If you wear it, that place is dead touch, this error usually occurs when the screen is dropped, in water, is pressed on, replaced with a poor quality screen…
