After iOS 8.2 upgrade, screen no longer displays color.
I have restarted the phone several times.I have played with the accessibility settings (grayscale and invert colors) but that has not solved the problem. when I turn my phone and the orientation switches, I see a brief flash of color, but then it is gone (when grayscale is on there is no color flash).
