iPhone 5

The iPhone 5's camera might have a flaw. If you point the camera toward the sun or bright lights, a purple halo appears around those light sources, and in some cases, purple lens flares also appear within the frame.

We took three similar shots in the same conditions to create the picture above, using the iPhone 5, the iPhone 4S and the high-end Nikon D300 digital SLR as a control. As you can see, the iPhone 5 is the only one producing this somewhat undesirable special effect in this instance. In addition to that huge purple blowout around the sun, you can also see a lens flare that looks like a purple rainbow lower in the frame.

Comments on tech site AnandTech's forum mention the presence of these artefacts when the camera is pointed toward a bright light source, and then moved so that light source is off-screen. You can see an example of that here.

It's not clear whether the problem is a software issue, or as some have guessed, the culprit could be the fault of that sapphire lens cover Apple added to the iPhone 5. Whatever the problem is, according to CNET, "another person who spoke with Apple support was reportedly told that there have been a lot of calls about this problem." 

In our testing, the blown-out parts of the picture where the camera was pointed at the sun were obviously hindered by a purple haze with the iPhone 5. However, when shooting toward the sun when it's slightly out of the frame, we were able to make both the iPhone 4S and the iPhone 5 produce that purple haze artefact. In the comparison below, the iPhone 4S's purple haze was much more visible than that of the iPhone 5.

However, in this shot comparing both cameras, there were no visible artefacts on either one:
