Features
One UI was designed as part of a goal to make Samsung's hardware and software "work together in perfect harmony" and provide a more "natural" experience on large-screen smartphones. One UI displays most of the features[7] that were in the Samsung Experience UX. A prominent design pattern in many of Samsung's system applications is to intentionally place common features and user interface elements along the middle of the screen rather than near the top. This makes them easier to reach with a user's thumb when using the device one-handed.
For similar reasons, apps utilise large headers to push their main content towards the vertical centre of the screen. The navigation bar supports the use of gestures and the usual 3-button system, while a system-wide "night mode" was also added (which gives UI elements and supported applications a darkened color scheme). As with Android Pie upstream, the Overview screen of recent apps uses a horizontal layout, as opposed to the vertical layout of previous versions.[8][9][10][11]
One UI Core
One UI Core was a slimmed down version of the original One UI feature set aimed towards the lower-priced A, F, J, and M series low and mid-range devices. Devices running One UI Core typically have a reduced set of features compared to the full version of One UI running on higher end devices.[12]

While Android 9 “Pie” did come with gesture support, it was only available on Pixel devices and stock AOSP devices and is said to be 'half baked' by many users. However, Samsung decided to create their own gesture system to navigate devices with One UI installed. To achieve this, the user has to swipe up from the bottom of the device in the three locations of the 'buttons' to navigate. The gesture system has received mixed reviews.[25][26][27] The incoming call screen got refinements. One UI 1.0 was released on 7 November 2018.
