Apple Inc is recalling a limited number iPhone 6 Plus phones due to faulty back cameras that take blurry photos.

The affected phones were mostly sold in a 4-month period between September 2014 and January 2015, Apple said on its website. The company, whose shares were set to open at their lowest this year on Monday, said a small component in the affected 6 Plus’s iSight back camera may fail.

Apple said it would replace the phone free of charge if the iSight camera takes blurry photos and falls into a particular serial number range. Eligible serial numbers can be checked on Apple’s website. iSight’s Optical Image Stabilisation (OIS) feature works by taking four individual shots and combining them into a single image. 

It uses the phone’s A8 chip, gyroscope and M8 motion coprocessor to measure motion data and provide precise lens movement, and was designed specifically to compensate for shaking hands. 

The faults were initially reported last year on Apple support forums. One user, known as oneZer01, wrote: ‘iPhone 6 Plus rear camera is not focusing, won’t remain stable and is blurry, no matter how still I [am]. ‘Automatic or manual focus not working either, [but the] front facing camera works fine.’ 

A further video was posted on YouTube by Bnorty that showed the screen flickering when they attempted to take a photo, or film a video. 

On its official support site, Apple said the affected handsets fall into a ‘limited serial number range’ and were sold primarily between September 2014 and January 2015. Concerned users can check if their handset falls within this range using Apple’s online tool.
