I just bought an iPhone 4S last weekend and the camera won't auto-focus well on close up objects. If I press on the screen where I want to focus on it won't focus at all and will be blurry, but the background of the object is focused very well. My iPhone 4S is jailbreaked and I don't want to restore it to bring it into an Apple Store to get the camera fix. Is there anyway I could fix this?
