Many Galaxy S23 and S23 Plus users say they have noticed banana or ring-shaped blurs in pictures taken from the phones. Basically, some parts of the images appear blurry and out of focus.

Photos taken by the Galaxy S23 and S23+ are blurry in some places
I agree that it is field curvature but in the shown cases it is asymmetric and that emphasizes the problem. It is very prominent on one side and barely noticable on the other side. Maybe de-centered lens. … and while it is a common phenomenon I did not see this on the Pixel 7, Samsung A52S or iPhone I checked. Which means Samsung is just not able to control it.”-Reddit user Sedazin
It appears that most of the affected units were manufactured in Vietnam, which is where the bulk of Samsung phones are manufactured, but some Indian and South Korean units also have the issue.
Some Galaxy S22 owners said last year that the pictures the phone produced were blurred at the edges, but that issue was fixable in settings and didn’t affect a significant number of users.
Don’t confuse it with the edge blur of the S22. with the S23, the blur is banana-shaped around the center. that is something completely different. Here the lenses are probably not good. Photographing documents sharply is almost impossible. it is also noticeable in detailed landscape pictures. the pictures are almost all worse than with my old S10e. the S23’s automatic photo correction destroys each image to correct the blur.” – Reddit user Heinzi647578
