Few days back, Apple clarified that the purple haze showing up in the photos taken with the iPhone 5’s camera pointed at or near bright light sources is considered normal behavior and is exhibited by most small cameras.
Folks at Consumer Reports have carried out a series of tests with smartphone cameras and has found that though iPhone 5 did display a purple haze when photos were taken in bright light in their labs, it didn’t do so in any more pronounced a manner than did the iPhone 4S and Android based smartphones such as Samsung Galaxy S3 and Motorola Driod Razr Maxx.
All the devices were tested under the same conditions. Consumer Reports notes that the during their tests, the haze was sometimes purple, but sometimes some other color or even a rainbow.
All camera lenses, even those made for expensive SLRs, can yield lens flare, which is produced by scattered reflections inside the lens from a bright light source. How much flare appears in an image depends on how you orient the lens.
For example, lens flare often occurs on bright, cloudless sunny days, when you include the sun itself in the image or, if the sun isn’t in the image, strong sunlight shines into the lens from an angle. Some expensive advanced cameras, and even many point-and-shoots, have special lens coatings that can limit or eliminate such flare, and possibly associated colored haze. So can attaching a shading hood around the lens’s edge. But smart phones’ cameras are designed differently, so it’s typically more difficult for manufacturers to minimize flare in them.

While they admit that the problem is annoying, they didn’t see it as a major issue as it’s not likely to affect most photos.
They’ve advised users to minimize the issue by using their hand to shield their phone’s camera lens from sunlight or to avoid the issue by reframing reframing the photo or video whenever a bright light source appears in or near the frame.
