Android 10 + One UI 2.0
Samsung will be rolling out its new Galaxy S20 smartphone with Android 10 out of the box, and sliding on its own in-house One UI 2.0 over the top. Samsung made its One UI visual overlay for Android simplified, and "designed for clarity".
This was done to keep consistency between Galaxy devices, from the older-gen Galaxy S10 through to the new Galaxy S20, and even the foldable Galaxy Z Flip and Galaxy Fold smartphones. It means you can go between devices and not have a huge change in the UI -- which will make for a better Galaxy experience going forward with newer Samsung devices.
Samsung has designed its One UI 2.0 with a "streamlined design" that keeps you up to date, without distracting you -- with notifications taking up less space. This is a nice touch that I actually dig with One UI 2.0 -- but I still use my own launcher on top (of both my Galaxy Note 10+ 5G and Galaxy Fold smartphones).
One UI 2.0 includes Dark Mode, something I personally adore -- with an "enhanced Dark Mode" on offer here with One UI 2.0 that gives you improved battery life, too. Samsung has darkened the menus and features across the entire of One UI 2.0 for a more streamlined, darker, battery-saving look.
One UI 2.0 also packs customized color preferences and even high contrast elements, for the ultimate in tweaking -- and like custom keyboards like SwiftKey, Samsung's new One UI 2.0 also packs a new keyboard that is "fine-tuned with increase visibility and definition".
