The problematic iPhone 5 display to users a purple halo effect when they point the camera towards a strong light source and try to take a picture. Several people have complained about the existence of this via Twitter, the picture above confirms its existence, and many users are not too happy. iPhone 5 it has a set of sapphire lenses and it is speculated that they are at the root of the problem, but not everyone who owns an iPhone 5 terminal has the same results when pointing the camera at a strong light source, so we are talking about a relatively isolated problem.
Sapphires are available in a variety of colors and the light refracted by the lens could show the color of the sapphire in pictures, the problem is that users cannot get rid of the effect after taking a picture. I don't know how important this "problem" is, and I think a typical Apple answer would be: don't point the camera at the sun because you won't record anything anyway, so I don't really see why you would be so worried even if the terminal your pictures would be like this.
UPDATE: the problem is found in several types of cameras, including old iPhones, so it is not only related to the iPhone 5.
