I am at a loss. My sprint note 4 will only usb charge. No ac charge. Any charger any cord. It does not matter. Ive change usb flex port twice. Once by me the othe by a reputable phone repair company. Made no difference. Only thing left is replacing motherboard. Or is this a software issue? Its less than a year old but rooted. Root 2nd week i owned it. Has nothin to do with problem. Surely someone else is experiencing this problem.
