I have an iPad Air 2 running iOS 9.0.2 and can't figure out a way to delete a duplicate picture. This happen when I take a screen shot which in turn places a copy in both the camera roll and screen shot folder. I see no reason to keep two copies or loose the space the second copy takes up. When I tried to delete from either location, the picture is deleted from both locations. Can someone tell me if it's possible to delete just one?
