spot on camera, but lens is clean

So when I take a picture there's always a spot in the middle like a dirt spot. After I installed the latest phone update it showed up and I thought it was just some stupid feature. Now its annoying and I have cleaned the casing and plastic covering the lens several times. Its still factory sealed so how could that smudge spot still be there? Does this count as faulty manufacturing?

Plus can someone link me to a post explaining what all that means?

 

turns out it was an imperfection in the lense. tmobile is replacing it for me.
