I upgraded from S10e to S21 5G and I'm very disappointed with the main camera, it takes pictures with blurry edges, only the central area is real sharp. This is especially noticeable when I take a picture of a light object on a black background. Colors are also not correct. I suppose that it may be a problem with post-processing. My old S10e takes perfect sharp pictures, I have compared both smartphones under the same conditions.
I suppose that the problem is in post-processing, because if I take a picture of the same object on a light background, the edges look much sharper.
If you have a S21 phone you can repeat my experiment - just take a picture of a dollar bill on a black background.
@JoeBlackFox What are your camera settings on ? Some settings like the highest resolution on have trouble focusing but adjusting the that can fix up-close focusing. in other words try the [9:16] ratio instead of the 3:4 64MP settings since that one has trouble focusing up close
