Samsung order galaxy s21

Product Name: Samsung order galaxy s21
Selling a Galaxy s21, I paid 500 for it but upon receiving it found that the camera has black spots in regular mode (4th pic) but in the better pictured mode it still looks fine(3rd pic). The black spots can be cleaned but the phone has to be taken apart, which i don't wanna do. The phone also has order one of the tempered glass screen protectors on it. The price is very negotiable. nothing less than 200 though.
