I will post photos if it happens again but I was too frantic to remove them. It looks like when I cleaned it with a microfiber rag, some of the fibers got stuck around the Apple logo. I had to put a little bit of water and rub it a bit. Then I also had to actually grab to remove a few stubborn ones. It's not such a big deal as I can feel the logo sticks out quite a bit. iPhone 7+ jet black. Anyone else experience this?
