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

When you dropped your iturd in the toilet you probably got a little poop smeared on the lens just wipe it off!

But seriously if its blurry during the process of takeing a photo it could be you have one of the focusing tools on or sutoing does it seem to go in and out then most likely.

Other thing could be you were taking a shower with your phone and the steam may have built up condensation in the lense because it wasn't completely sealed maybe due to a manufacturing issue or you dropped it and it jangled it.

Or worse case there could be a hairline crack if the blurryness is spcific to an area or more predominent in an area of the screen it could be a crack.

I suggest turning the phone over and looking at it maybe you can put your trouble shooting skills to work and figure it out.

Also i recommend look up on google if this is an common issue i know auto focus was a problem on iturd 4 or 4s w/e but as far as i know it was fixed in the iturd 5. But check just type your issue in there something like
