Warning, incoming rant!!!
I just got the update today on VZW, and like most major updates, it sucks! Perhaps it's just my personal opinion, perhaps others may agree. One thing right off the bat, the clock shifted to the left side of my notification bar. No option to move it. Why?... because the S10 has the dumb full screen with the dumb hole punch selfie cameras. Well guess what? The S9 and Note9 do not have this, so why make it a universal thing rather than device specific? I was able to hack it and move it back to the right side where it belongs. If you wish to do that, here's the instructions. Proceed at your own risk.

Second thing, Always On Display. The clock I use is smaller now, doesn't show owner information, doesn't have background option. (Notification icons are now colored, which is cool, but that's about all it's got going for it)
Third thing, The "Full screen" experience is lame. If you don't have the nav bar set to gestures, the nav bar won't auto hide like it use to, so full screen apps (that you can't change display settings on, because they're "optimized" for full screen) are proportionately hidden behind the nav bar. So changing this to the new gesture setting solves that problem, but it's just another change that I'll have to get used to.
I don't mind new features, but what pisses me off more than a one legged man in an ass kicking contest is that when these new features come out, they don't keep the old features giving us the option to change it back. Yet, let's still preach that Android is all about customization. Well, whether it's Google, Samsung, or any carrier, I feel like lately, my customizing options are getting slimmer and slimmer with each new version of Android.
Lastly (for now) I have my phone set to not auto update system. In Developer options, "Auto update system" is ticked OFF. Yet this morning, I see a funny icon on my always on display. I wake up the phone, and low and behold, "New software has been downloaded and is ready to install" WTF? I thought it was just a monthly security update, so I proceeded. Now I'm stuck with this goofy BS that I didn't want.
My message to everyone who gets a new phone, then is always anxious to get the update to the next version of Android...
