I have a 4G Galaxy S3 with a dead battery. I plugged it to a wall charge for over an hour but nothing happens. There's no red charging LED nor is there a charging animation on the screen. I tried inserting another battery from a 3G Galaxy S3 (the batteries look the same and have the same specs) and that one charged just fine, so I think the problem is with the 4G battery. Is there anything I can do to save it?
