rear camera unable to focus

Hi there Geraldinetay,

Welcome to Apple Support Communities.

If I understand correctly, there's an issue with the photos or video taken with the iSight camera on your iPhone 6 Plus appearing blurred or out of focus. The article below provides a lot of great information and troubleshooting tips that should help you resolve the issue with the iSight camera on your device.

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. Make sure that there’s nothing blocking the camera lens. If you’re using a case, try removing it.
   With iPhone 6 Plus, a metallic case or magnetic lens could interfere with optical image stabilization. If you have a metallic case or magnetic lens attachment, 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.
4. If the color seems too bright, or you see double-exposures of moving objects, make sure that HDR is set to Auto or Off. Tap HDR at the top of the screen to choose a different setting.

Ciao.
