Over the course of the past several years, Samsung’s One UI has drastically changed. In the beginning, One UI 1.0 made Android much easier to use and understand than ever before, and now we have an advanced, AI-powered collection of devices in the Galaxy S and Z series.
One UI 7 was focused on maximising the potential of personalisation, enhancing productivity through integrated connectivity with other devices, and locking in an even closer knit experience for users in Galaxy’s universe.
However, with One UI 8, Samsung is taking a step towards expanding the possibilities that AI and system intelligence provide in developing a streamlined look and feel.
In this article, we are going to take an in-depth look at both versions with respect to their visual design, performance advances and how the upgrades have changed the level of safety and security as well as customisation choices available. And how much of an increase in AI they provide.
So let’s dig in!

1.The Evolution or Revolution of the Design Philosophy?
One UI 7: Mature, Polished, Familiar
The design of One UI 7 took features such as the use of rounded shapes, clean/clear layouts and a clear focus on ergonomics to allow for one-handed operation and build upon them to create a user interface with smooth, fluid animations, as well as a consistent look and feel. The overall feel was minimalistic yet vibrant in the visual elements and useful, and maintained a consistent look and feel throughout the interface and throughout the app.
One UI 8: Minimalism Reimagined
Samsung went much further with One UI 8 to reflect a design that is more futuristic than previous versions. The most significant visual differences from the previous version are listed below:
- More fluid animations due to improved frame smoothing.
- Redesigned, flatter, and more dynamic, icon representations.
- Adaptive colour accents to provide more gradual changes depending on the brightness of the wallpaper.
- Edge-to-edge UI components offer a cleaner and less cluttered appearance.
The end result was a cleaner and more futuristic UI that feels lighter and more refined than the previous version. If One UI 7 was refined, One UI 8 is a more premium version.
Overall, One UI 8 is better than One UI 7—not necessarily because of the drastic change in appearance, but due to its modernized and more fluid design.

Multi-Tasking and
One UI 7 provided the tools needed for power users to be as productive as possible, such as
Smart Pop Up View, multitasking gestures, split screen mode, and improvements made to DeX to allow a seamless transition from the phone to the TV.
One UI 8 continues to build on top of this with some refinements that create an overall more seamless multi-tasking experience.
Pairing two applications side-by-side is even more seamless with One UI 8. Resizable floating windows now respond in a more intuitive way. Dragging and dropping files across apps is a smoother experience. AI now predicts the apps that the user wants in split screen mode. Samsung DeX is now more stable, with the added benefit of being able to scale to a higher resolution.
For the power users that use their phones as a mini-laptop, these refinements will be huge improvements.
6.To summarize, One UI 7 had an excellent camera and gallery layout;
it introduced some quick-toggles for camera settings as well as updated some manual controls. For the gallery app, smart organization of photos and limited editing functions were introduced.
One UI 8 further offers enhanced user experience and artificial intelligence (AI) advancements.
For example, one of these improvements was Smart Scene Detection (AI) which allowed users to identify subjects in photos automatically and make edits accordingly. Other features include improvements to the Pro Mode for more simplified usage and enhancements to live previews, which provide users with a clearer view of what the camera sees.
Additionally, some extra improvements were made for each gallery app. For example, the ability to recognize objects more accurately in the gallery app was improved, and Automatic Albums and Memories were created similar to iOS.
