Camera is not focusing , what should I do ? Even iphone is not broken or fell on the ground .

Hello,

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. For iPhone models that feature optical image stabilization: A metallic case or magnetic lens could interfere with this feature. Try taking a picture without the case or lens, and then compare the quality.
3. To focus on a certain object or person, tap that object or person on 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 you adjust 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.
