I just got back from having my headset speaker replaced (i think it blew) and when i got my phone back, the back cover is really loose. I pointed this out and they offered to put a new cover on. The new cover did the same thing and they said that it must have been like that when they got it in. I saw the guy struggle to take the cover off when he went to pull the battery and check water spot. Does anyone else have this problem and how do i fix it. It takes absolutely no effort what so ever to take the cover off now. The slightest bump or slide and its off.
