Samsung's new Galaxy Z TriFold makes a bold claim: it can run DeX directly on its own screen. That means a phone-sized device can behave more like a tablet or a pocketable desktop — no external monitor required.
DeX on a phone — finally
Until now, Samsung phones needed an external display (wired or wireless) to launch DeX. Tablets could run DeX natively on their own screens, but phones lacked the necessary real estate. The Galaxy Z TriFold changes that. With a 10-inch foldable display — the largest ever on a Samsung Galaxy phone — the TriFold matches tablet screen space and can host DeX right on the device.
What’s new in DeX with One UI 8.0
Samsung built the new DeX experience on top of Android 16's Desktop Mode inside One UI 8.0, and the improvements are practical, not just cosmetic.
- Multiple workspaces: DeX supports up to four virtual desktops, so you can separate tasks — for example, one for email, one for creative apps, another for meetings.
- App limits per workspace: Each workspace can run up to five apps, letting you keep focused toolsets for different workflows.
- Resizable widgets and windows: Widgets are resizable, windows can be resized or minimized, and frequently used apps can be pinned to the taskbar for quick access.
- Customization: Expect display rotation handling and on-screen keyboard appearance options to tailor the experience to how you work.
Who benefits from on-device DeX?
This is a win for mobile professionals, road warriors, and anyone who needs more screen and multitasking power without carrying a laptop. Imagine replying to emails, editing documents, and running a video call across separate workspaces — all on a single foldable device. That said, the TriFold isn’t a full desktop replacement: heavy-duty computing and larger peripherals still favor laptops and desktops.
In short, Samsung’s tri-fold design leverages its extra display to bring tablet-like productivity to a phone form factor. For people who value multitasking and mobility, on-device DeX on the Galaxy Z TriFold is an intriguing step forward.
