My iPhone (XS Max) was already lagging when I updated to iOs 14. but now with the 14.2 my screen became COMPLETELY unresponsive. When I start the phone the screen works for about a couple mins, then it just stops completely ******* working. I took it to apple and the dude try to convince me that I needed a new screen for $300 or the new iPhone 12 Upgrade. The screen was WORKING before 14.2 and so was the phone! It's clearly a software issue and needs to resolved with IOS 14.3 or iOs 15. whatever is next. And now apple stopped signing 14.1 So I cannot even downgrade. Complete BS
