I've been having a problem over the last several months where upon turning the display back on after turning it off (hold the display button) the screen is washed out white. You can still see a little bit of the display, but the grand majority of it is washed out. The screen will come back to normal usually when you put it in sleep mode and come back.
I'm running 3.90 M33 and have had this happen through a number of CFW versions. I've been looking around the forums but can't find anything about this.
Any hints would be appreciated as it's VERY annoying.
