gunnr, I had an issue after replacing mine which may help. I noticed the + on the screen was always being pressed, so I slipped a piece of a negative or something as thin, even your fingernail where the screen mets the case lip and this relieved the pressure that was pushing on the lens. Maybe take the cover off and recheck the fit.
