BANGALORE: 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 four-month period between September 2014 and January 2015, Apple said on its website. The firm, whose shares opened 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.
