Default Pictures being blurry when you tap a spot on the screen to focus?

I am not sure when this started. I noticed that when I tap the screen to focus on a certain area, it blurs it out instead. When I click a photo without tapping the photo turns out to be sharper.

Using tap to focus on the word AMOLED:

As you can see the word AMOLED is kind of blurry as I tapped to focus on it.

Without tap to focus:

Here the word AMOLED is very crispy without tap to focus.

Can someone please try this and post about the results?
