Your iPhone Is taking Blurry Pictures
The iPhone’s camera system generally works flawlessly, but there may be times when it starts taking blurry pictures out of the blue.
The first thing you need to do to solve it is to clean your lens. Clean the camera lenses with a soft, slightly damp, lint-free cloth. Make sure to dry the lenses after you’re done.
If that doesn’t fix the problem, try playing with your camera settings. You might have changed something, causing the camera not to focus properly.
Also, try taking a picture of a different subject or from a different angle. Something in the way may prevent your iPhone’s autofocus feature from working correctly.
Last but not least, make sure to restart your iPhone and update it to the latest software. It might sound like a cliche, but these tips often work for almost any issue.
