Maybe it’s just me, but I tend to see a lot of motion blur on that label, an amount that could easily account for the blur on the fingertip, too. Given the ultra-short focal length of mobile cameras and the large focal depth that comes with it I would expect very little out-of-plane blur on the fingertips.

The label is very blurry.

Plus, the point is that the picture is not a blurred picture of a finger. There is a lot of information in this photo which could be used to help to guide the de-blurring process.
