Q: My iphone 4 camera won't focus when taking a picture?

I know violence isn't the answer, but I found that after my camera became blurry I Banged it on my grandmothers antique glass ashtray a few times and it seemed to clear up the problem. Just saying...

I was having the same issue and removing the top film of this foam fixed it.

I updated my iphone and now my camera is blurry. sadly this was realised after christmas day present opening, so incredibly dissapointed, I should of used a proper camera. I have now read a ton of other forum iphone users moaning about the same thing. now fix the problem!

I am having the same issues. Still no reply from

Apple

hi.i'm not from apple but im a big fan of it.so lets get to ur problem..have u tried checking if the rear camera lense is wiped clean?if so try goin to the camera thru the phone and then holding the place u wanna focus until the lock activates..there are other solutions..still if u have the problem try removing the back door of the phone and re focusing without the back housin..this is the problem in most phones..so if the camera focuses now..try cleanin the lence from the inside view of ur rear housin and fix it back..give me feed back once u do all that..then i'll proceed u to the rest of the steps.and also apple support is not bothered since they have our money but still i love apple products

All of a sudden mine stated to not focus.  I tried tapping the camera lens and that did nothing.  Then I "spanked" the back side and that worked.
