Okay, so I leave it on the wall charger for the night, and when I wake up the battery has been fully drained, for some odd reason. So I go to plug it in, and when I do so, the notification led stayed blue for one second, then turned off. When this happened, a something that I have never seen before popped up on the screen. It showed the typical empty battery symbol that you normally get when your battery has been drained, but then there was a little yellow triangle at the bottom, and in the triangle was an image of a plug. It wouldn't take a charge, so I unplugged it, pulled the battery and then waited a few minutes. Then, when I went to plug it back in, the blue led turns on again, but it does this for only one second, like before. Now the screen doesnt turn on at all, and whenever I press the power button, the led just blinks one time. The screen doesnt even turn on, anymore. Has anyone else had this problem? I haven't rooted/flashed the phone, either.
