The display quality on my iPad Air 2 changed suddenly yesterday and all photos now appear grainy or overexposed and blurry. Even pics viewed on web browser, so it is all display not just my photos. Photo optimization is NOT enabled so it’s not that. I have rebooted. I updated to iOS 12 and problem is still there. It’s like a filter has been applied to my screen. I have cleared memory space and only 10gb of 16gb in use. HELP? I want my sharp images back please!
