Can you attach an example of blurred picture?
Please ensure that the lenses are really clean and you don't use any cover which could affect the picture quality. I suppose you don't use any protector (platic or glass) on the camera?
Looks like the sun causes this fogs, if you talk about the blur on the tree.
But it seems in focus to me, bad picture quality but in focus ? Or there's something i dont get.
I just read someone with a similar issue saying giving the phone a tap near the cameras made it focus properly again, and because of this Samsung replaced it under warranty
