If you purchased an iPhone 6 Plus between September of last year and January of this year, there’s a small chance your back camera is a little screwed up.

According to Apple, a “failed component” makes some back cameras on the model take blurry photos.

If you’ve noticed inexplicable blurriness to some of your shots, and your device falls within this subset, Apple will replace your camera for you.

“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 affected units fall into a limited serial number range and were sold primarily between September 2014 and January 2015,” says the company on a new help page.

“If your iPhone 6 Plus is producing blurry photos and falls into the eligible serial number range, Apple will replace your device’s iSight camera, free of charge.”

You can check your serial number here to see if you qualify.

Do note that your phone needs to be in good enough shape for Apple to be able to replace the camera.

“If your iPhone 6 Plus has any damage such as a cracked screen which impairs the camera replacement, that issue will need to be resolved prior to service. In some cases, there may be a cost associated with the repair,” says the company.
