Black line in pictures

[IdkRedWater]

I have a Samsung galaxy s20 ultra and when I take a picture with the 1x camera i have this black line

Its the black line on the side. I have tried cleaning the lens and the glass of the lens but nothing seams to work.  What is the problem?

Can that not be seen on the lens or cover with the naked eye?
