My iPhone front camera is blurry?

The normal camera works fine but when I flip it it is blurry almost smudgelike and i can't take any pictures with it-when i press the button nothing happens. Then i have to restart the app so it would let me flip it back. I'm not sure if this is a hardware or software issue- i have tried rebooting the app and the ipod itself but nothing changes
it doesn't appear to be damaged on the outside, but i don't know
thanks for any help!

to get an image idea: go to this one

basically it's like the image on the far left but it's a worse and i can't take pictures with it

Going by the picture you link, the solution is to replace your phone with an iPhone 5.

Front cameras as notoriously bad. If your is exceptionally worse, have it fixed by Apple.
