Screen has a mind of its own...
My iPhone XR has been opening/closing apps, scrolling, and typing on it's own without me even touching the screen. All the youtubing and googling I've been doing has only produced a couple of options: update the ios and hard reset the phone (I've done both) but the problem persists. I still have a year or so before I am due to upgrade... any suggestions on how to fix this??? Thanks!
iPhone XR, iOS 14
