In response to a user's question about "purple highlights" appearing in a photo taken with the new iPhone 5 near a bright light source, an AppleCare warranty service representative said the effect was "normal behavior" for the new device.
In a response from an Apple representative obtained by Gizmodo, the Cupertino-based engineering team recommends keeping the camera away from bright light sources to avoid the purple flashes that some users have already dubbed a defect.
AppleCare Support answers:
Various media outlets have previously reported that so-called "purple glare" is a common problem in all modern digital cameras, especially those with the small sensor used in smartphones.
The "violet haze" was thought to be caused by a new sapphire lens protector, component placement, or a new matrix, but the more likely cause is a trivial color distortion, presented in this case as chromatic aberration.
According to information taken on the forum to discuss this problem on the Apple support site, one of the users still agreed to replace his iPhone with a new one, but it is still not clear whether the replacement is an isolated case or whether devices with such a "defect" will be replaced to all the victims.
