dark to black to normal? I look at my phone this morning and it was this crazy looking pink and green and my wallpaper was all crazy then i slide it open and close it and it turned blue then after a while it got very dark to where u could barely see then it turned black, i turned it off and it was normal and sometimes if i wait long enough the black screen turns back to normal colors but the pink&green,blue dark colors and black are just somethings that happen sometimes it gets very light and other times it gets very dark with green and blue pixels any help please?
