Anyone else have problems with their micro usb not charging? I picked up a used phone from someone on craigslist and everything was fine except soon as I went to charge it the phone wouldn't recognize the usb connection. Yeah cl is total scam city, but my friend needed a phone since his old phone crapped out on him. I was able to charge the battery with on of my universal chargers so I ruled out the battery and tried multiple usb cables and not much luck. It would charge if you positioned the cable in a very specific way, but that even stopped working. It is still covered under warranty, but I'm afraid Samsung will blame it on the consumer. The phone itself barely has a scratch on it, just the charge port is crap.
