My iPad touch screen becomes intermittently unresponsive (might not respond to touch briefly, maybe 1 to ten times a minute). Not sure if it is the touch screen or processor overload.
I have a 12.9 inch iPad Pro 256 GB with cell & WiFi purchased from Verizon. I am running 11.4.1. My iPad screen began being intermittentlay unresponsive several months ago (actually, if I remember correctly, this started after I upgraded to 11.2).
For instance, I may be trying to scroll down a long page, and for the first several finger strokes, it works normally, and then the next several finger strokes do nothing and the page slows down and stops scrolling. Another example: I’ll be typing, and all of a sudden, several letters don’t respond... instead of the letter on the keyboard turning grey as it is struck, it stays white and those letters don’t appear on the ‘page’. Another example: if I use a keyboard that allows gesture writing, a swipe from one key to another will all of a sudden not be a solid curve, but instead, a dotted line curve, like a rapid series of on/off in response to my finger crossing the screen.
The problem seems to be most extreme when I try to play SimCity or Tumblr, but occurs in every app. However, the Apple apps seem to be the least affected.
i have used a touch screen app to test if there are any areas of the screen that don’t respond to touch; that seems to be fine. I have done a factory reset and reload from an archival backup; the problem is the same. I tried upgrading to the 12.1 public beta; the problem persisted. I tried factory reset and just loading 11.4 without restoring my data... at first, the problem disappeared, but then slowly reoccurred without loading any apps or any data.
I took it to an Apple store on campus at the Harrisburg Area Community College while I was traveling... they ran a set of diagnostics and couldn’t find anything wrong.
This problem is slowly driving me nuts... it’s very frustrating to try to use a device when the input keeps failing sporadically. Any help would be very much appreciated.
