Galaxy Note 4 Black Mark on Photos

A week ago, I received a Galaxy Note 4 and love it. I took many photos and they looked really good but today I noticed a faded black smudge on the top right when I take photos now, I looked around and it most people think it's dust in the inside the lens, can anyone help me? I'd be devestated if I have to send it back before Christmas.

Can you post an example of one of these photos?
