[Q] No USB Connection and Phone thinks it's always charging
I picked up a used galaxy s4 the other day and it seems like the USB port is bad. When I try to connect it to the PC it is not recognized at all (I've tried different computer, different cord, different ports, everything) and often it seems to think that the charger is connected when it is not. Charging the phone, however, does work. I'm pretty sure this means the USB port is bad, but wanted to make sure there was nothing else I could do before I ordered a replacement board and started taking the phone apart.
