Samsung One UI 8 reveals new multitasking for the Galaxy Z TriFold
Samsung's upcoming Galaxy Z TriFold has surfaced in One UI 8 code and UI animations, revealing a significantly improved multitasking experience: the ability to run three full apps side‑by‑side on the main display. As pictured above, this is a departure from the current three‑app layout used on devices like the Galaxy Z Fold 7, where one application stretches across half the screen and two others share the remaining half in split quadrants.
What changes in One UI 8
Findings from SammyGuru indicate One UI 8 will offer an option to display three full apps in a horizontal row on the TriFold's expansive main panel. Iconography and an animation in the interface point to a true three‑pane layout rather than the existing uneven quadrant arrangement. The One UI 8 animation also provides an early glimpse of the TriFold's main display aspect ratio and how content will adapt when the outer screen transitions to the unfolded canvas.
Product features
Key capabilities expected
- Three‑app, side‑by‑side split screen for full‑width multitasking.
- Outer screen homescreen that expands into a wider two‑page layout on the main display, similar to Galaxy Z Fold 7 behavior.
- Smoother app continuity and window resizing animations driven by One UI 8.
Comparisons
Compared with the Galaxy Z Fold 7, which already supports three active apps but in a mixed layout, the TriFold's expected side‑by‑side configuration will better utilize the tri‑fold form factor. This makes the TriFold more competitive with other large foldables and multitasking‑focused tablets, offering a desktop‑like workflow in a pocketable device.
Advantages
- Enhanced productivity: run email, documents, and chat simultaneously for true on‑device multitasking.
- Improved developer opportunity: apps can optimize interfaces for a wider, multi‑pane layout.
- Better media and content workflows: reference materials, editing tools, and previews can coexist on one screen.
Use cases
Journalists, analysts, and mobile professionals stand to benefit most—imagine video conferencing on one pane, notes in another, and a browser or document editor in the third. Traders and power users can monitor feeds, execute trades, and chat with clients without switching apps. Creators can preview content while editing and referencing sources at the same time.
Market relevance
The Galaxy Z TriFold could accelerate adoption of tri‑fold foldables and push competitors to rethink multitasking on mobile. By integrating deep three‑app split‑screen support into One UI 8, Samsung positions the device as a productivity leader in the foldable market, nudging app developers to better support multi‑pane experiences.
Release timing and remaining unknowns
Samsung is widely expected to launch the Galaxy Z TriFold before year‑end, but many specifications—camera setup, battery life, pricing, and developer tools—remain unconfirmed. We'll need hands‑on demos to judge real‑world performance, app compatibility, and battery impact when running three full apps simultaneously.
Overall, One UI 8's leaked visuals paint a promising picture: tri‑fold hardware finally matched by thoughtful software multitasking that can reshape how professionals use foldable phones.
