Newest 12.9’” iPad Pro, 1 TB/6 Gb model running iOS 12.1.3., no Screen Protector applied. Seems to occur on all areas of the screen. Screen freezes. Started cropping up just in the last few weeks, seems to be getting worse. Reacts as though the screen was very dirty or my finger isn’t contacting then screen completely. Interestingly, the freeze will sometimes stop when the iPad is changed from any angle to level. Also, sometimes if allot of finger pressure is used then the freeze is gone. Mostly, there seems to be no problem at all, then the problem happens again out of nowhere. Is this a common or known problem that will probably be fixed with an iOS Update? Is there a Setting to increase screen sensitivity to touch? Or should I use Apple Care and get it replaced?
