Lately I've noticed that whenever I take a picture, this noticeable spot has shown up on them, and I was wondering what it could be. I don't think it's any dust in the lens (or maybe it could be?), mostly because you can see through it. Honestly, the pictures don't do justice, but it shows it to a degree. 1. I've already tried cleaning the lens and that didn't work. 2. It apparently only shows up in picture mode because I can't see it when I change it to video mode? It's so weird. Any idea on what it could be?
