Apple has today issued a recall for the rear-facing iSight camera on some iPhone 6 Plus models. Apple says there may have been a faulty component inside of the camera in models sold between September 2014 and January 2015. They have created an online tool allowing you to check the serial number and see if you device is eligible for a replacement. If it is, Apple will replace the camera of no charge.
According to Apple’s article, the bad component caused photos to be blurry and look bad.
