I've had this phone for close to a month now and it's great, admittedly I have issues with the Exynos version but as we cannot get the SD version, no point complaining further about it.
The Zoom on the S20U is amazing! No doubt. But it also has a massive processing issue! The viewfinder between 30x and 100x shows one thing but the post processing image is massively different. And that's not a good thing. It SMOOTHS the image to ridiculous proportions. And what could actually be a decent picture of a building, or even the moon ends up looking like a blurry mess. Especially recently, we had a Pink Super moon in the sky, and what the viewfinder was seeing was spectacular!! And its so frustrating that once the picture was taken, the resulting image in the gallery was a basically a yellowy blurry circle.
Really hope Samsung addresses this in future updates because the latest update did not bring improved zoom processing.
I can maybe show you something I noticed..
When I take a picture at long zoom it smoothes the picture.. makes it blurry.. i took a screenshot and it shows the more sharper image..
Guys, if you use the burst shooting (pull down on the shutter) instead of normal shot, then there's no processing and the pictures actually look like on the viewfinder :) Stupid, but it works.
How samsung can let this happen is beyond me... Probably so they can remove it on the s21 and say it's better..
You guys are so right about the image processing done on the high end zooms of the S20U, useless photos. But there's a simple hack to get photos as you see on the screen or sometimes better. All you have to do is turn on the FLASH and take the high end 30x or 100x zooms. Flash doesn't reach that far obviously but this tricks the phone to not Post-Process it like some watercolour painting. Try it for yourselves and let me know!
