Samsung has unveiled its first tri-fold phone, when unfolded twice, reveals an immersive 10-inch display.
Samsung’s three-screen-machine can face the world in a form factor that looks like a conventional single-screen smartphone – the 6.5-incher, 2520 x 1080 “cover screen” – or fold out to offer a tablet-like experience in which three panes combine into a 10.0-inch 2160 x 1584 “main screen”.
The phone weighs 309 grams and hides a 5,600 mAh three-cell battery under each of its leaves.
When folded so only the cover screen is visible, the phone measures 159.2 x 75.0 x 12.9 mm. After opening, it measures 159.2 x 214.1 x 3.9 mm.
A Snapdragon 8 Elite Mobile does the driving, helped by 16GB of memory. A trio of rear-facing cameras offer 12MP ultra-wide shots, 200MP wide-angle snaps, and a 10MP telephoto unit that can achieve 30x digital zoom. Identical 10MP selfie-cams are available from the Main or Cover screen.
“Samsung’s relentless pursuit of new possibilities continues to shape the future of mobile experiences,” said TM Roh, Chief Executive Officer, President and Head of Device eXperience (DX) Division at Samsung Electronics.
“Through years of innovation in foldable form factors, Galaxy Z TriFold solves one of the mobile industry’s longest-standing challenges — delivering the perfect balance between portability, premium performance and productivity all in one device.
Galaxy Z TriFold now expands the boundaries of what’s possible for mobile work, creativity and connection.”
To balance the power of an ultra-quality device in a thin, portable frame, a re-optimization of the core foldable technology had been applied. Every part of the device was crafted with deep attention to structural innovation and product assurance:
Samsung’s Most Advanced Hinges Yet
Samsung refined the Armor FlexHinge to meet the unique demands of Galaxy Z TriFold. Two differently sized hinges with a dual-rail structure work in harmony, creating a smoother, more stable fold despite varying weight and components across the device.
The hinge structure also allows the screen panels to meet securely with a minimal gap, enabling a thinner, more portable device.
Restructured Foldable Display
Galaxy Z TriFold introduces new display technology made for the 10-inch screen that folds twice into a pocketable phone.
A reinforced overcoat has been added to a shock-absorbing display layer for better resistance across the dual-folding device.
Advanced Materials on the Exterior
The titanium hinge housing introduces a thin piece of metal that protects the folding mechanism and resists wear over time. The frame of the device is supported by Advanced Armor Aluminum, a high-strength alloy that adds rigidity without increasing bulk.
The frame helps ensure that the screens don’t make contact with each other, and a ceramic-glass fiber-reinforced polymer back panel keeps the design thin yet resistant to cracks.
High-Quality Inspection, on Each Device
Every unit goes through a series of strict quality checks to achieve every small requirement.
For instance, CT scanning of the flexible printed circuit board verifies that it has been correctly manufactured according to the design, ensuring accuracy and reliability before bonding it together with the other internal display components.
Laser scanning verifies that all internal components are mounted precisely at their intended height, securing surface quality.
Powered by the Largest Screen
Productivity on Galaxy Z TriFold is heightened with powerful experiences, customized for the 10-inch display — the largest screen ever on a Galaxy phone. Like the users who inspired its dynamic design, Galaxy Z TriFold is powerful, versatile and ready for the modern AI era.
When Galaxy Z TriFold opens, the screen performs similarly to three 6.5-inch smartphones across the 10-inch display, giving users more room to multitask during their day.
Users can use the screen with endless versatility — they can create across three different portrait-sized apps side-by-side without interruption, resize apps in multi-window to view the most important information clearly, or hold it in a vertical orientation when reviewing documents for improved focus.
For example, an architect drafting design plans for a new home can use the large screen to operate three applications at the same time, to review blueprints, write a proposal, and calculate measurements in a single, multi-window workspace.
If a call comes in unexpectedly, they can answer without disrupting their layout or losing their momentum. When it’s time to jump back into work, the Taskbar at the bottom right of the display instantly resurfaces recently used apps, bringing the full setup back into view with a single tap.
Familiar apps and features, such as My Files and Samsung Health have also been optimized for a large screen, allowing users to organize and understand insights at a glance.
Samsung Dex
Galaxy Z TriFold is the first mobile phone to have standalone Samsung DeX available, meaning users can set up a full working environment from virtually anywhere.
By going to the Quick Settings panel and selecting DeX for Galaxy’s most advanced work setup, users can access up to four workspaces that can each run five apps simultaneously.
From there, they can review and edit a meeting presentation in one workspace and then quickly navigate to another to chat with friends and shop online.
For even more productivity, users can add a secondary screen in Extended Mode, which enables a seamless dual-screen experience with an external monitor. Users can easily drag and drop apps across screens and work across both screens with desktop efficiency.
Users can also add a Bluetooth mouse and keyboard, instantly creating the ultimate portable workstation for complex projects or creative designs.
Galaxy AI
Every detail of Galaxy Z TriFold is designed for excellence — and with Galaxy AI, those capabilities elevate the device by making every feature more intuitive on a large screen.
Features like Photo Assist, including Generative Edit and Sketch to Image, adapt to Galaxy AI flexibly with impressive scale, enabling users to capture and create with Samsung’s most versatile creative platform. Users can also easily compare before and after edits side by side.
Browsing Assist can simplify how Samsung Internet is used as it can provide instant summaries or translations as needed.
Gemini Live on Galaxy Z TriFold is enhanced with multimodal AI that understands what users see, say and do. Users can seamlessly speak contextual questions and get answers without having to switch between apps for high level multitasking.
The bigger screen provides design advice — when a user shows it a room, a shopping site and paint swatches, it will provide a custom recommendation.
With screen or camera sharing on Gemini Live, users can simply ask questions about what they are viewing to get real-time assistance and insights — all on one device.
