Ok, I get it. People are tired of haters trying to bash Apple for every little thing. But seriously though, I just took the same picture with an iPhone 4S and an iPhone 5, and the purple haze is there in both, but definitely more noticeable on the 5. I do understand that even though it's Apple, it's still a phone camera, so I shouldn't expect SLR quality, but it does seem like a bit of a step backwards IMHO (and I'm definitely not an Apple hater, considering I've owned a iPhone 3, 4, 4S, 5 + iPad 2, 3).
Just out of curiosity, for those that are experiencing this (like I am), are you using a white iPhone or a black iPhone? Both my 5 and 4S are white, and I previously had haloing/lens flare issues with my white 4S taking pictures with a flash in a really dark room/scene (no case), where my buddy at work in the cube next to me could take the same picture with his black 4S with no issues.
Who knows, maybe the phone color has nothing to do with this, but just curious if there's any link?
