사용자에게 답변하기: Galaxy s3 usb port not working?Hey Everyone! I too have had much difficulty with the Galaxy S3's charging port, but I just found out why the phone won't charge and a quick solution for it without rigging the phone up with rubber bands or hair ties. The charging pins are only on the top of the port, and most every charger is not thick enough for the S3, so you simply slide a piece of paper under the bottom half of the port, then input your charger. The paper will keep it held up. This has been working for me and hopefully it does the same for all of you!
