I just bought the Acer a500 a week ago and love it! It's my first android device and I have just been been getting used to it. TuneIn radio is probably my fav free app so far. Somewhere in the settings I turned on the function to leave the screen on while charging and now I hate it but can't find where to turn it off. I've gone through the settings and am probably just overlooking it. Please help Thanks in advance.
