I noticed as well Zoom transition it's better after the update.
My Note 20 Ultra was awful in low light and night mode.
The S24U is miles ahead in night mode.
I have been taking pictures in low light yesterday for the 1st time and I noticed that when I turn on the camera it takes a bit of time to Acquire sharpness of the picture, after that it's ready to shoot, but of course you can shoot before that if you want, it's still going to process the picture in order to get the best of it, than it's going to process the picture a little bit more after the picture is taken, because I've seen the 3 dots working after I took the picture.
I don't mind the processing, of course I want tye best quality of my pictures, the other phones were taking time just to focus in low light, this phone takes one good shot at one time.
What I want is the phone to be able to take the picture without me seeing it's processing the picture, because I feel it slows me down when I want to take the picture.
Also if I could keep the enhancements I chose for my pictures for every zoom would be great.
