iPhone charger quit working, now phone is acting strange
My daughter is having some issues with her iPhone 5. The other day, she was getting an error message saying "charging is not supported with this accessory." Weird. It's the factory charger. Ok, maybe the charger is on the fritz. Tried a new one and that seemed to fix the problem. Then, later in the day, her phone shut down by itself. Fluke? Maybe. Then a few hours later, it was like the phone crashed. The phone did not shut down, but the apple logo appeared on the screen like when it's booting up, and when it did come back on, the screen was super dim for a while. I'm beginning to think there is a hardware issue that is developing. Has anybody else experienced anything like this? I have not tried to restore the phone yet.
Thanks for any information you may have!
