Well, I bought a Samsung Galaxy S3 in may this year. It worked fine but yesterday I was trying to charge my S3 and all it was showing was an empty, grey battery. After a few seconds the screen went black. When I push the power button the same grey, empty battery pops up and disappears a few seconds later. I tried to charge it using a mac and pc but the problem wasn't fixed. Tried to reset the device by performing a factory reset but nothing happened and I still can't charge and use my phone. I really don't know how to fix this. I viewed a few other threads about this but al the given solutions weren't helping for me! Hope someone who might have had the same problem knows the solution.
