Samsung One UI 3.0 promises next level visuals, and functionality. The lockscreen pin pad is beautiful. I always thought that the settings menu was hard to use and not very easy on the eyes but the updated version has darker greys (removing that yellowish hue) and is more organized and compact!
My favorite visual feature: BLUR! Using blur to control contrast from the background is the best. One UI has a better color scheme, background blue and more rounded rectangles. No more sharp edges and dimming!
My favorite feature so far: The new biometrics. The biometrics are supposed to be a lot faster.
I'm planning on buying an S20+ on the day of One UI 3's release.
It just looks disgusting to me, too much like iOS. From lockscreen, to the blur effects, the shape of the icons, their size and arrangement, the way they divide options on holding an icon resembles the 3D touch, the widgets view on the lockscreen and the pin entry, it's too much of imitation. I mean, if I want that, why would I buy a Samsung device. I hated it. Another thing to point out is the settings button in the quick settings panels, they took it to the top, which de fefets the purpose of one-handedness, which was initially their aim with One UI.
