Weird question, but is it possible for a case to cause the front glass of the screen to shift or mess up the digitizer or whatever. I'm asking because when I brought my iPhone 5S into the apple store they said they couldn't get the phone casing off to look at the inside components because the side was stuck and wouldn't separate. they switched it out for a new one. Now I'm worrying that my glass is getting shifted around or pressed in because I do have a tendency to remove my phone case a fair bit to clean the phone. And I don't know if I'm imagining touch response issues or not. The lady said it could be s few things such as a manufacturing issue. But I want to be sure.
