Apple has issued a support document about the "purple lens flare" issue on the iPhone 5, but don't expect any type of recall or fix ad it is considered a common occurrence.

Following up on an email that was sent a customer last week, Apple has now released a support document about the purple lens flare issue. As the document states, Apple feels this is an issue that happens in most small cameras, and has even been present in previous generations of the iPhone. The fix is fairly simply according to the statement:

Most small cameras, including those in every generation of iPhone, may exhibit some form of flare at the edge of the frame when capturing an image with out-of-scene light sources. This can happen when a light source is positioned at an angle (usually just outside the field of view) so that it causes a reflection off the surfaces inside the camera module and onto the camera sensor. Moving the camera slightly to change the position at which the bright light is entering the lens, or shielding the lens with your hand, should minimize or eliminate the effect.

Of course the issue is that you won't normally see the problem until you look at the picture, and by then most moments are gone.

As someone who has dabbled in photography, yes, this can happen fairly easily, but learning your angles isn't always the easiest thing in the world. Just be careful is about the only advice we can suggest and try to figure out what caused it when you see it happen.
