Samsung has published the first video that demonstrates how to shell One UI. It has been specially developed for smartphones with large screens, so they were easy to use.
The company completely redid the shell and changed the control logic. Now all the necessary elements are closer to the bottom of the screen, so to them it was easier to reach. The top half of the screen is given over to large items and headings.
It is worth noting that in One UI have a dark theme, which may be included on the schedule. It is quite unusual, because the manufacturers do not add the dark design of the system. The only problem with dark themes is that it only works in the default Samsung apps. The likelihood that other developers will redraw your app in a dark style is extremely small.
One UI operates on the Android platform 9.0 Pie. Shell is now available in beta version for Samsung Galaxy S9. The official presentation of the One UI will be held in February 2019 along with the Galaxy S10.
