My S3 doesnt charge properly. Sometimes its charges, sometimes it doesnt. Its really annoying... It'll be plugged in charging then it doesnt. But once it doesnt work, it doesnt work after a while. Then itll work again after I try to plug it in. I had my phone jtagged recently and my phone didnt do that before until after I got it. The guy said he didnt do anything he just put everything stock. My phone is indeed stock, 4.3.
This is really annoying though..
