I'd take the skin off first and see if that fixes the problem.
I had no problem with the skin. But I do have the problem with the display. Image retention and yellow screen. I suggest you to take it in.
I wonder now if he has a Samsung LCD - he might not want to send it in.
took it in today. The magnet was fine but as suggested above, the thin layer created by the iCarbons cover was putting pressure on the gasket and caused it to fail. Removing the cover restored functionality... I'll email them to let them know.
