So this is perhaps a bit odd... today for the first time /ever/ my device rebooted itself while it was sitting on the table next to me. I have had a rooted phone since before i even walked out of the T-Mobile store with it and it has never misbehaved or done anything strange. Now, however, i noticed what can only be described as a small series of chevrons or arrows that were blinking on the lower middle of the screen. Whether i was on the main menu of my home screen or a side screen it didn't matter, there they were. I shot footage of them with my camera and posted it here... YouTube - ‪Android WTF‬‎ ... as you can see, it's almost as if they were showing a new user how to scroll and see the app drawer. However, as i have been running CyanogenMod for ages, i don't have an app "drawer" anymore. Opening the applications screen and then closing it again made the arrows go away. I have not seen them since. Maybe people will tell me this is perfectly normal, but i have truly never seen them before and am quite puzzled.
