I have read through other threads and still have questions about my phone not charging. I plug the usb into the phone and the icon with an empty battery and a blue lightning bolt through it appears, so the phone is obviously getting some power through the usb charger. After a few minutes the screen will start blinking quickly and eventually slow down to blinking every 5 or 6 seconds. I've left it there for an hour and the phone won't even turn on. The battery I was using wasn't dead when I turned it off last. I have now tried a new battery that hasn't gotten wet and the problem is still occurring. And this charger has worked before and I've also tried a different charger with the same results. I've looked in the usb port and all 5 prongs seem to be there.
