Q: My back camera become blurr

Hi Sarah

There is an iSight Camera (rear camera) Replacement Program for iPhone 6 Plus.

Subject to the terms of the program, if the rear camera on your iPhone is producing blurry photos and falls within the eligible serial number range, Apple will replace the iSight camera, free of charge.

Your photos are blurred or out of focus

If your photos are blurred, out of focus, or have dark spots, try these steps:

1. Make sure that the camera lens is clean. If you need to clean the lens, use a microfiber cloth. If you see dirt or debris inside the lens, take your device to an Apple Retail Store or Authorized Service Provider for more help.
2. With iPhone 6 Plus and iPhone 6s Plus, a metallic case or magnetic lens could interfere with optical image stabilization. Try taking a picture without it, then compare the quality.
3. Adjust the focus by tapping on the person or object in the preview screen. You’ll see the screen pulse or briefly go in and out of focus as the camera adjusts. In photo mode, try to stay steady when adjusting the focus. If you move too far in any direction, the camera will automatically refocus to the center. In video mode, you can adjust the focus before you begin recording.

If you still have issues with the focus on your camera, contact Apple Support.
