While swimming with gopro . I found that when recording video in and out of water ok but when you stop recording and still on you go under water and come back up with out touching any thing it changes to a different mode ie( time lapse or camers or butry shot or settings modes).this might have to do with temperatures different in water to out of water but it's annoying when filming and you stop filming then want to start again and it's in a different mode.
