Why is my iPhone 4 camera blurry?

It started to take blurry pictures or grainy pictures after I updated to iOS 7 and I can save pictures to my phone from google just fine and it's not blurry then. Why?

I had the same problem. My fix was to remove the case, The case blocked the flash and screwed up the picture. Wipe the lens if you haven't already.

  • Why is my iphone 5 rear camera suddenly blurry? So it's not that it's dirty, I've tried cleaning it. It was literally fine yesterday but all of a sudden it like won't focus. When I first switch to the rear cam, for a split second it's fine. Then it just goes to being unfocused. Is it just a problem with the auto focus? If so, and I have to take it into apple, will I have to pay for a solution? If so how much. P.s my front defacing camera is completely fine
