since there are problems with the camera software, I am opening this thread to discuss your experiences and software update news.
I got my S20U Exynos variant today and straight out of the box there was an OTA (430MB) available which stated that the camera experience has been improved. It got better because I have tested it before the update but the autofocus is still "jumpy" and has problems with objects that are near to the phone. Even if i turn on the setting to adapt autofocus to the selected object in the viewer, it still jumps
EDIT: I did some tests today with my own face using the main sensor and the oversharpening / skin smoothing is gone. I tested it with HDR turned off and on.
Look at this video guys. Focus hunting is gone. Sorry, I have orange blinds and the sun was shining directly on those.
