iphone 4 blurry pictures

Had iphone 4 for couple years. Pictures have been crystal clear until recent update. Now pictures are blurry. Camera will not focus clearly when taking picture and are blurry after picture is taken.

May sound silly but check your camera lens mines is scuffed

Thanks Orisons but lens not scuffed. Picture clarity is a result of the update. No doubt in my mind.

Update to iOS 6 you mean? I haven't noticed any degradation on my iPhone 4 with iOS 6. The quality is the same.

Raz0rEdge, Yes the last most recent update. I also did my wife's phone and her camera quality was not affected. I also researched this tonight on internet and other iphone owners are having the same problem with their phones after updates. Many indicate it affected pictures already taken, and some like mine.
