Galaxy S5 will suddenly only charge with wall charger
I have had my Galaxy s5 for about 3 months. Since I got it I always charge it with the USB3 cable that came with it (uses both sides of the charging port). The phone has never been rooted. Suddenly, yesterday it stopped charging via a USB port or my car charger (2Amp Car charger that came with the phone). I have tried 2 different official Samsung cables, and the cables work fine with any wall charger.
Please help! I rely heavily on my mobile charging options, such as in my car or charging via a PC USB port. I took the phone to the ATT store, but they just charged it in via a wall charger and said it worked fine. To my knowledge the phone has not updated recently.
