Apple has issued a recall for thousands of iPhones.

The technology company say the recall is over a defect that causes them to take blurry pictures. The issue is with the iSight camera on the back of the iPhone 6 Plus -- and not the "selfie" camera -- according to the company.

The recall affects phones sold between September 2014 and January 2015.

Apple says it will replace the cameras for free. Affected customers can go to an authorized service provider, any Apple store, or contact technical support to set up a swap.
