Thanks for letting me know what that was!
I didnt do anything other than waiting on facebook to load and it was just a white screen, and when I went to pick up my phone it was black. I hit the power button to bring back up the screen and nothing! SO I poped out the battery and restarted it. and this is the screen I got. But like I said i hit the home button and it was fine.
when the phone crashes it will boot up to that screen...its used to hard reset your phone to factory settings.
