    My iphone 4 is only 40 days old and it wont auto focus. when i hold the camera close to some text it is blurry and unreadable, and when i tap to focus the only thing the phone does is lighten or darken the screen depending where i tap. the front camera works fine if i hold it close to text and take the photo but that is pain. anyone know how to fix this? i can hold my wifes 3gs the same way and the text is readable. I have tried restoring as new and back up with no luck, and i have tried other camera apps and it is the same result.

    Mine has developed the same issue. I'm heading up to Sydney at some stage to have it replaced.

    It's a hardware issue, the auto-exposure works properly but the lens isn't moving so it means it's a faulty phone. Thankfully the rest of it works just fine so it's not a huge deal.

    i have iphone4 32gb.
    my auto focus also not working.i was tried everthing but not work.
    -restore firmware/ios = not working
    -install super camera = not working

    and lastly i've got the problem solved!

    step 1:
    open your default camera application and dont close it.

    step 2:
    flick the rear camera using your finger at the top side and the back side of the camera lens,
    and that same time too try to tap your screen to help your camera to force/help/make auto focus function to work.

    and now your camera + auto focus is working!!

    What do you mean by flicking the top and behind the camera? Can you show with a video?

    Does the focus get better the harder you hit it?

    You know where I'm going with this...

    My iphone4 camera stopped to focus too, after so much hard "flicking" to the point of "banging on the desk", I still couldn't get it to work :(

    Time to send it back, sigh..

    I'm really happy that this worked for me as well. I had to tap it pretty hard several times but now it focuses again. Thanks for the tip!!

    This may lead to the deduction that loose rattling autofocus rings might be better in the long run. Hah. Goodluck,op.

    I have the same problem with my iPhone 4 16GB. The camera won't auto focus after flicking and trying to get the auto focus square focus automatically on random spots n focus lengths. Ive tapped on the screen heaps of times and nothing. Every photo taken weather close or far is fuzzy and undefined. I guess this is a hardware issue. As I tried other camera apps( camera+ and big button) and still the same thing. Does any one have a good solution that works. Would really love your feedback here guys? PS, phone has never been dropped either.

    My iPhone 4s is having focus issues as well. I didn't know the replacement lenses were so cheap... gonna have to browse ebay and pick one up. Doubt i will be able to replace it on my own though.
