ios 7.1.2 on ipad 2 color distortion

Uploaded ios 7.1.2 on ipad 2 and all photos and video now have waves of greenish blue distortion. It's like super saturation. Pretty sure there's no dead pixels because this distortion problem only appears in places where there are deep colors, primarily in photos and on video, not on white screen, and the distortion effect moves around on the screen. Is there any way to adjust color saturation or similar tools? Thanks.
