The green light is on, and the battery symbol indicates it's charging (lightning bolt present), but it's not. I've tried wall plug and computer, different cords, etc. I've also tried the power and volume-down buttons. Someone told me to make sure the phone is "off" when I plug in to charge. I can do that, but the phone is continually turning itself back on. It stays on just long enough to tell me that I need to plug it in, and then it tells me it's going to shut down. So there is no way to keep it turned off and charging, I don't think. Can anyone help?
