That's on the beta, I have a Samsung s20 ultra, beautiful phone, got it when it first come out.
Camera was fine. The Samsung started to bring out camera fix updates and after the UI 4.1, the camera is struggling to keep in focus on certain zoom ranges, and they don't want to fix the problem, so hopefully in the big new android update. Hopefully they'll fix the problem or I'll buy an iPhone.
I did install Google pixel camera app on my phone and it worked brilliant, Google camera app is the best on the market as its algorithm is superb compared to any other manufacturer. But then Samsung had a firmware update and now it only works with one camera lens , so I deleted it, but with a s21 and s22 you should get all cameras working
