My S3 wont charge at all?!


I'm sorry, but that thread's first two posts -- by that thread's starter (aka, its "original poster" or "OP") -- are just ridiculously wrong and misleading.

I have, however, added a third post to that thread which sets straight the record; and provides any Samsung Galaxy famly phone user -- particularly a Note II user -- with pretty much everything s/he needs to know about this subject.
 
Here's a link to a YouTube video of an s3 charging port repair if you wanted a DIY'er. I think they have a repair service also.
 
My phone did the same thing. Did you ever get it to charge and or turn on? Mine decided to do it last night and i can't get it to do anything.
