One UI One UI 1 One UI 1.0 is the first version of One UI (based on
Android 9 Pie), and was released on 19 December 2018. It brought about many features which were becoming increasingly popular among various apps. Dark mode (then named Night mode) was one key feature 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. While Android 9 Pie did come with gesture support, it was not available on Samsung 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. The incoming call screen got refinements.
One UI 1.1 brought stability fixes and performance optimizations, primarily for the camera, fingerprint reader, and facial recognition. One UI 1.1 was released alongside the
Galaxy S10 series. This is the first version of One UI to be included as part of newer Samsung Galaxy devices since 2019. Later releases required some devices from 2018.
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. It was launched with the
Galaxy Note 10 series devices on 12 August 2019. It was included with select Galaxy A series devices from 2019,
Galaxy Tab S6 and Tab Active Pro. Although Samsung Experience was rebranded to One UI in late 2018, some apps like Settings or the Calendar still identify One UI 1.0–1.5 as Samsung Experience. This would be corrected with One UI 2 as the Samsung Experience name would later fade away with the release of Android 10 for those supported devices. Additionally, app versions were 10.x and with each generation of One UI, the version of apps was incremented by 1 for every One UI version.
One UI 2 One UI 2.0 is the second version of One UI and is powered by
Android 10. 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, sound themes and harder Location permission access. The incoming call screen got improvements, including the phone icons. One UI 2.0 was officially released for the
Galaxy S10 and
Note 10 series on 7 November 2019 with other devices received the update thereafter.
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, the Galaxy Fold, and select
Galaxy A series devices as a software update on 24 February 2020.
One UI 2.5 first released with the
Galaxy Note 20 series and
Galaxy Tab S7 series on 21 August 2020 and on the Galaxy Z Flip 5G on 7 August 2020, with the update later being released to select supported devices. It 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.
One UI 3 One UI 3.0, the third version of One UI and based on
Android 11, was released for Galaxy S20 devices beginning on 2 December 2020 after starting beta testing in August. This version 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, redesigned incoming call screen, and smoother animations and transitions throughout the whole UI among other features. Blue Light Filter has been renamed to Eye Comfort Shield.
One UI 3.1 was first released with the
Galaxy S21 series and began rolling out to other supported Galaxy devices, starting with the
Galaxy S20 series on 17 February 2021. While there were no significant user interface changes, it included several new camera feature improvements, such as enhanced touch autofocus and auto exposure control, an improved Single Take feature, and software implementations such as Object Eraser, Multi Mic Recording, Private Share, and others. This version is also the first to replace the built-in Messages app with Google's version. However, this change only applies to phones released in 2021 with Android 11 or later. Older phones retain Samsung's Messages app, which has been present since TouchWiz. Devices such as the S10 and S20 remain unaffected and do not include Google's Messages app.
One UI 3.1.1 first released with the
Galaxy Z Fold 3 on 11 August 2021, although it first appeared with the
Galaxy Tab S7 FE on 18 June 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. The new features were rolled out to all supported devices, but those that neither are classified as foldable phones nor tablets continued to show their software version as One UI 3.1 after the update. Unlike the previous and next releases of One UI, this version was only available to foldable phones and tablets.

Android 12, started beta testing on 19 July 2021, as the fourth generation of One UI. It was publicly released to the

One UI 4.1.1 is based on
Android 12L which optimized the Android OS for alternative form factors such as foldables. It first released with the
Galaxy Z Flip 4 and
Galaxy Z Fold 4 on August 23, 2022. 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). The new features made it to supported bar-type phones but these phones continued to show the software version as 4.1 after the update like One UI 3.1.1 as it was only available to foldable phones and tablets.

Android 13, was announced on 12 October 2022, as the fifth generation of One UI. It was officially released for the
Galaxy S22 series first starting 28 October 2022 with other devices received the update months or weeks afterwards depending on the country. 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. One UI 5 also brought refreshed icons with a slight gradient and subtle differences.

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. Even though other features made it to non-foldable phones, the latter devices continued showing their software version as 5.1 after the update like One UI versions 3.1.1 and 4.1.1 as it was only available to foldable phones and tablets.
One UI 6 One UI 6.0 is based on
Android 14. It was officially released for the
Galaxy S23 series starting 30 October 2023 with other devices received the update after several weeks or months depending on the country. 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.

Galaxy S24 series. This and later versions of One UI mainly include new
AI-based features that are available only on flagship devices sold in 2022 and later. These features are marketed as "Galaxy AI" and rely on a combination of local models and cloud-based models. In mainland China, the cloud partner is Baidu providing its Ernie model, while in international markets (including Hong Kong, Macau and Taiwan), the cloud partner is Google providing its Gemini Pro model. Features available on all applicable devices include enhanced battery protection designed to prevent battery degradation, Super HDR 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. 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.
One UI 6.1.1 was released on 10 July 2024 with
Z Flip 6 and
Z Fold 6. This update includes several new Galaxy AI features such as Portrait Studio, Suggested Replies and Sketch to Image.
