I came home to turn on my tablet and it came up said battery was dead and quickly shut off. No biggie as I plugged it in and left it alone. Now the screen is turning on and off. When on it shows a battery outline with a loading circle, then flashes to a battery with 5 little circles under it, end of battery turns blue then the screen shuts off. Been sitting here for 20-30 min doing the same thing. Did this brick on me? I am running all factory, no root or anything else.
