so, new think to work on in my tracking stuff, specifically on my phone's screen on stats
basically, I have my phone scheduled to automatically poweroff at 01:30 and power itself on again at 07:00. the thing is, when it shuts down, the screen turns on to display the boot animation. and that records a "screen on" event. but it doesn't record a "screen off" event because, obviously, the phone is already powered off by then
