I'm wondering about iOS 11 and aftermarket screen replacements. I replaced my screen about a month or so ago and tried upgrading to iOS 11 today and the touch response is unbearably slow. I also noticed that the speakers aren't functioning. When I try to play any audio it either gives an error or just does nothing. I'm in the process of restoring back to 10.3.3 and so far just from the setup screen it seems to be functioning like it should.
