I swear you go out your way to downplay the iPhone 5.
Like I said before, it is not an issue at all. The only time it has occured is in the test photo I did to see if the camera does indeed have the problem. Unless you just so happen to be taking a picture of something fairly dark with a superbright light source perfectly lined up with the very edge of the screen then the camera takes good pics.
Notice how there is like 1 thread where someone reported it. The guy said how to make it happen, and everyone said they can replicate it. If it was an issue in day to day shooting, trust me, MacRumors forums would fill in in about half a second. People filled the whole forum with the iPhone 5 being scuffed out the box, so if there was an issue with everyones camera with normal use, we'd here about it.
If you are actually trying to take a photo and you are getting purple flare, it can be solved by literally aiming about 1degree further away from the light source.
The fact that even after it has been reported, there is still only one small thread on MacRumors to be found, is pretty telling IMO.
