I too have a problem.
That when I play a song the screen becomes greyish rather than showing me the song art or the artist.

at night when i charge my phone it will randomly put in its own passowrds to unlock my phone, and it will always lock me out for a LONG time the first time i caught it happening was for like 40 mins next was for 252 mins. but sometimes i cathch it before it locks me out completely. and am able to stop it.

Do you use any flip covers or anything on your screen?
