Mobile Blurry Look

Hi.
I started making a mobile game. I taked a screen shot while testing it in my mobile:

We can see that it is a bit Blurry.

Is there any way i can correct the blurr completely and make it look more retro like this game:

(From Pixel Dungeon)

In the editor it looks ok, I already correct a bit whith this tutorial {[link text][3]},but in my mobile it still looks blurry.

Thanks.
