Oooo that's an interesting one, does it not show when you look for the roll out information, I was able to find it once via the Samsung website, don't ask me how though lol, sort of stumbled across it, it's a huge list.
Also I don't know if it would matter about your data connection ie: UK sim & roaming or Ukrainian local/WiFi.
Try & find that update list to see if Ukraine is on there or a nearest country, but that one ui 4.0 isn't locked to just Note 10 phones, so all newer phones will get the update at some point in the future if they haven't already.
I also have Note 10+5g which is still on 3.1 updated in Jan 8th this year.
You'll need to find your specific basband version number & build number, some also have android letters in the update ie: R & Q. You can find all that info in settings>software info, also check the phone status to see if it still says "official" meaning its not been jailbroken etc.
Here's the info link for that last security update, find your phones info & see if it's had this latest patch too, if it has i think you'll be fine for the next UI update.
Sorry I can't help you more.
