I need something that tells me what is turning on my backlight in the middle of the night.

I leave the setting to turn backlight off automatically unchecked. Because I dont want my phone, which is my alarm to freeze when I am sleeping.

Problem is I wake up every morning to the backlight on... It does it before 2am I think, because I woke up at about 2am accidentally, and it was on.

Is there any kind of logger that will let me see what is running at that time? Preferably right when the damn light turns on?

I dont care really about the light, but I dont want my screen to get dimmer cuz of age, more than it has to of course.

I know this is a common problem, but is there any way to freakin track it?
