Replying to Please help fix my gopro +vid

so yea idk wtf happened but all the sudden my goprp aint filmin so smooth anymore on a count of the picture is all blurry. I already tried cleaning the lense with many different camera products so its not that. there is however a 1mm gap between the lense and the rubber thing that usually surrounds it tightly but only for a small section around so im thinkin perhaps condensation from the other side of the lense?? Any ideas what could b wrong NS?
