I have had this happen twice now, The Screen will not timeout and turn off, it just stays on. (pushing the button will turn it off, but then when it comes back on it stays on until you push the button again) I have to reset the phone to get the screen to time out again. I do not have "stay awake" under applications / development checked. I do not have any "screen" utility type apps or any smart actions that deal with screen timeout. Anyone else have this issue?
