I've never had that problem or read about something like that. The only instance I know of where the backlight turns on for seemingly no reason has something to do with the device's reception and tower communication. Are you on a EV/1x fringe area or have any signal fluctuations like that where you're at? And to answer your question, I'm not too sure if there's a logger for something like that, I could be wrong though.
