Apple iPhone 6 Plus - Gold-2

Apple has announced an iSight camera replacement program for the iPhone 6 Plus after discovering a small number of handsets have shipped with defective sensors. Affected units can produce photos that look blurry, but Apple promises it will repair them for free.

"Apple has determined that, in a small percentage of iPhone 6 Plus devices, the iSight camera has a component that may fail causing your photos to look blurry," the company explains. "The affected units fall into a limited serial number range and were sold primarily between September 2014 and January 2015."

Even if your iPhone 6 Plus isn't taking blurry images yet, its camera could fail later on if you have an affected unit, so you might as well take advantage of Apple's free replacement offer. You can find out whether your handset is eligible by visiting its program page and entering your serial number.

If your iPhone does need attention, you have three options: You can either visit the Genius Bar at your local Apple store, take it to an authorized service provider, or speak to Apple Technical Support. Before you take any of those steps, however, Apple says you should backup your device.

It's possible, then, that some device will simply be swapped rather than repaired. But be warned: Apple says that if your iPhone shows any signs of damage — such as a cracked screen — this must be repaired before your iSight camera is fixed, and "there may be a cost associated with the repair."

No iPhone 6 handsets are affected by this issue.
