Both mine and my wife's iPhone 4S seem to be having lots of trouble focusing after upgrading to iOS 6. Trying to take picture of my newborn from about 18" away. It will not focus on his face. The face box pops up like its trying to, but the pictures background is in focus and his face is not. Same thing happened yesterday when I was trying to take some pictures of flowers outside. It seems the camera will not focus on singular objects that have a greater distance to their background relative to the focal length. Anyone else having this problem?
