For the record, I'm not picking on Samsung's S20 Ultra camera purely because of all the hype generated on its launch. I'm only going to pick up the two phones I have. My previous Note 9 which I have put into use for the additional overseas locations I use it for and my current S20 Ultra and go straight into Photo mode and shoot.

I'll let you be the judge. From my point of view, I will only say that personally, I thought the only photo I think the S20 Ultra turned out better was the photo of my children's book collection while calling out that the S20 Ultra photos were a bit over saturated. The S20 Ultra shots were blurred the closer you move towards the frame/edge of each shot.
Another interesting note is that I could not change the photo resolution on the S20 Ultra except to shoot it all the way up to 108MP which would not be the norm for me.
