Why does the preview image for my FFC look sharper than the actual captured image? I feel this has been a problem on my Sprint Galaxy S3. The preview looks very crisp but when I actually take picture it becomes faded and bit blurry.

I know it's not motion from the tapping the button because it does not do it remains clear if I take a screenshot of the preview which is more shaky than just pressing the screen.

I took a picture and a screenshot of the picture to show what I am talking about:

 
Preview / Captured image (click images for larger variants)

In the preview you can clearly see the texture of my shirt and the freckles on my face while on the captured image it is just a solid blur.
Do you have any image filters/effects/night mode enabled? Try disabling them all?
