A fan of purple lens flares?
Please read up on the camera issue if you haven't already.

The lens flare issue is a normal issue for small cameras. The iPhone 5 is worse then average for lense flare but most small cameras suffer from this effect. Don't want a lens flare? Don't take a picture with the sun or bright light in it.
Or alternatively upgrade your new iPhone 5 to an iPhone 4.
I agree, lens flare is an issue for small cameras, but coloring it purple is not.
