I forgot my charger when I went out of town so my phone died. Getting home I placed it on the USB charger for a day, during this time I tried several times to turn it on and it would not, red light was on constantly. I did some reasearch online and saw that if your phone is completley dead, a USB cord will not work, and that you need the wall charger. Now I placed it on the wall charger and the red light turns on.. then about 2 min later its off and the screen is on with a hour glass and lighting bolt but does not appear to be doing anything. What is going on? COULD it charge without the red light on? Has anyone experienced this? Any advice?
