One UI is a user interface (UI) developed by Samsung Electronics for its Android devices running Android 9 "Pie" and later. Succeeding Samsung Experience, it is designed to make using larger smartphones easier and be more visually appealing. It was announced at Samsung Developer Conference in 2018,[1] and was unveiled in Galaxy Unpacked in February 2019 alongside the Galaxy S10 series, Galaxy Buds and the Galaxy Fold.
It is also the software layer for their smartwatch Tizen and Wear OS platform, which Samsung co-developed with Google.[2] [3] As of 2021, it is also the software layer for the Microsoft Windows platform on Galaxy Book devices.
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[4] 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.[5] [6] [7] [8]
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.[9]

One UI 1.0 is the first version of One UI and is based on Android 9 "Pie". It brought about many features which were becoming increasingly popular among various apps. First and foremost, dark mode was added to make viewing in dark spaces easier on the user's eyes. This feature was included in many apps and eventually brought to iOS 13 and Android 10. The first version also brought native screenshot editing tools, refined curves, refinements to the Always-On Display (tap to show), an upgraded Bixby with support for remapping the Bixby button, and a new way to navigate the device: gestures released on February 20, 2019.
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.[22] [23] [24] One UI 1.0 was released on 7 November 2018.
One UI 1.1 brought a stability fixes and performance optimizations, primarily for the camera, fingerprint reader, and facial recognition.[25] One UI 1.1 was released alongside the Galaxy S10 series. This update is not available on the Galaxy S8 series and Galaxy Note8.
One UI 1.5 provided a native screen recorder, a "Power Mode" for higher system performance and exclusive early access Link to Windows support in cooperation with Microsoft.[26] It launched with the Galaxy Note10 series devices on 23 August 2019.
One UI 2.0 is the second version of One UI and is powered by Android 10.[27] It provides Galaxy users with a skinned Digital Wellbeing experience, a more refined UI in some default apps such as Device Care, a minor UI change to the clock position in quick settings, a native screen recorder, the new Android 10 gesture system, Dynamic Lock Screen (different wallpaper with every unlock), a Trash folder in Files, native Android Auto, and harder Location permission access. One UI 2.0 was rolled out to eligible devices starting 3 December 2019.
One UI 2.1 brought support for 120 Hz refresh rate, Quick Share, Music Share, additional camera modes, and native support for Live Captions. It was first released with the Galaxy S20 series & the Galaxy Z Flip. It also arrived for older devices such as the Galaxy S9 and S10, Note 9 and Note 10,[28] the Galaxy Fold, and select Galaxy A series[29] devices as a software update starting February 24, 2020.
One UI 2.5 was initially released on 21 August 2020 with the launch of the Galaxy Note 20 series, with the update later being released for the Galaxy S20 series along with older Samsung phones. One UI 2.5 doesn't bring radical changes to the UI, but there are plenty of new feature additions to the camera, DeX, gesture navigation, and other services.[30] [31] [32]
One UI 3.0, based on Android 11, was released for Galaxy S20 devices beginning on 2 December 2020. The update includes a few noteworthy improvements, such as a translucent notification panel, brief notifications, new volume controls positioned on the right or left of the device alongside the physical volume keys, slightly enhanced widgets, and smoother animations and transitions throughout the whole UI among other features.[33] [34] [35]

One UI 3.1.1 first released with the Galaxy Z Fold 3 on 11 August 2021. It made multitasking easier with enhanced multi-window and task-switching features and also optimized more apps to take advantage of the large screen devices such as foldables and tablets. As such it was only released to eligible Galaxy Z series and Galaxy Tab series devices. The new features were rolled out to all supported devices but bar-type phones continued to show their software version as One UI 3.1 after the update.
One UI 4.0, based on Android 12, is the fourth generation of One UI. It was released to the Galaxy S21 series on 15 November 2021. One UI 4.0 focuses on customization, privacy, and access to Samsung's expanding ecosystem.[37] [38]
One UI 4.1 was first released with the Galaxy S22 series. It brought minor changes; however, it did introduce features like Smart Calendar, added option to choose how much virtual RAM is desired (from 2, 4, 6 or 8 GB), redesigned palette picker, Smart Widgets, separate Left/Right audio balance, extra brightness toggle, Pro Mode on more cameras, Night Mode portraits, and other minor changes.[39]

This update also adds further Samsung specific enhancements to multitasking and optimizations for foldable smartphones (Galaxy Z Fold line) and large screen tablets (Galaxy Tab line).[40] Even though the new features made it to supported bar-type phones One UI 4.1.1, like One UI 3.1.1, was only officially rolled out to the Galaxy Z series and Galaxy Tab series.

Some features and changes include the ability to turn off the RAM Plus feature, where previously users could only limit it to 2 GB rather than turning it off entirely, and a redesigned way of customizing the lock screen, similar to iOS 16. Material You was also expanded to most of Google and Samsung Apps along with some third-party apps that support material you, allowing more ways to customize One UI. One UI 5 also brings refreshed icons for a more-refined look across the UI.
One UI 5.1 was announced on 1 February 2023 and released on 13 February 2023 with the Galaxy S23 series. It brought many new multitasking features, weather, new battery widget, Settings and Spotify suggestions, Camera and Gallery features, as well as improvements such as the ability to change color tone for selfies, enhanced image remastering, and revamped info display.[42]
One UI 5.1.1 launched with the Galaxy Z Fold 5, Galaxy Z Flip 5 and Galaxy Tab S9 on 11 August 2023. The update increases the number of apps shown in the taskbar with more recent apps, improves support for Flex Mode in more apps, allows for two-handed drag-and-drop file transfer and gives the ability to hide apps in pop-up mode among other features and improvements.[43]
One UI 6.0 is based on Android 14.[44] It was officially released for the Galaxy S23 series starting 30 October 2023 with other devices expected to receive the update thereafter.[45]
The update includes a redesigned quick panel with a new button layout, improved access to the brightness settings and a new notification layout that allows sorting by time. Other new features include a new default font, new emojis and an improved multitasking experience. Built-in Samsung applications such as the Camera app, Gallery, Photo Editor, Weather among others have also received updates to add more functionality and customization.[46]
One UI 6.1 was released on 17 January 2024 with the Galaxy S24 series. This update mainly includes new AI-based features that are exclusive to the Galaxy S23, Galaxy S24, Galaxy Z5, and Tab S9 series. These features are marketed as "Galaxy AI" and rely on a combination of local models and cloud-based models using Google's Gemini Pro.[47] In China the cloud partner is Baidu providing its Ernie model.[48]
One UI 6.1.1 is released with Z Flip 6 and Z Fold 6. This update includes own menu of Galaxy AI in settings.
Features coming to all applicable devices include enhanced battery protection designed to prevent battery degradation, SuperHDR for photos in the Gallery and on social media apps like Instagram and Snapchat, and the option to show the lock screen wallpaper on Always On Display. Simultaneously the merger of Samsung's Quick Share and Google's Nearby Share feature were announced allowing all Galaxy users fast file transfer with all Android and Windows devices using a single solution.[49] [50]
While not released alongside One UI 6.1, Samsung implemented Google's A/B seamless update technology with the release of the Galaxy A55. This works by installing updates to a secondary system partition that the device boots from whenever it is restarted.[51] [52]
As of 5 August 2020, Samsung offers up to three years of One UI and operating system updates and four years of security updates for the following devices.[53]
As of 9 February 2022, Samsung offers up to four years of One UI and operating system updates and five years of security updates for flagship devices sold in 2021 and later, and mid range devices sold in 2022 and later.[54] This includes the following device series.
