I understand that there are people who don't like major changes in new software updates, but the point is that it is just how it is. If you need help with new functions or anything, just ask *friendly* in this forum, and you get help. But please stop ranting about things you can't change anyway. It doesn't make sense at all.
I'm using Nova Launcher & an Icon package that I like - The UI on my device is virtually unchanged from Oreo to One UI - I've been using the same setup for several years & other than some minor changes (mostly done by me) There's very little difference in the appearance from my Note 2 to my S9+ AND it didn't matter if I was running a Rooted Custom AOSP Rom or stock Samsung Firmware - Just saying that YOU don't have to use what Samsung is using for their UI 🐧
