Samsung is already deep into foldable phones, including its latest Galaxy Z Fold 7. But now, the company is taking it a step further with its first tri-fold phone, aptly named the Galaxy Z TriFold.
As the name implies, the phone can unfold not once but twice on either side to open up a 10-inch display that rivals small laptops and tablets. Yet it’s still ultra-slim when fully folded into a traditional bar-style phone. When unfolded, it’s 3.9mm at its thinnest point.
The phone works using an inward-folding design that protects the main display. The folding mechanism has been precisely engineered for easy opening and closing, says Samsung, with an auto-alarm alerting you of incorrect folding through a series of on-screen alerts and vibrations. The Armor FlexHinge has been refined with two differently sized hinges and a dual-rail structure that Samsung says creates a 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. A reinforced overcoat has been added to a shock-absorbing display layer for better resistance across the dual-folding device.
Further, 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 fibre-reinforced polymer back panel keeps the design thin yet resistant to cracks.
Powered by the customized Snapdragon 8 Elite Mobile Platform for Galaxy,3 it comes with a 200 MP camera and the biggest battery Samsung has ever had in a foldable phone via a 5,600 mAh three-cell battery system in each of the three panels for balanced power delivery and all-day endurance. It also supports 45W super-fast charging.
When the phone is opened up, it performs like three 6.5-inch smartphones across the larger 10-inch display so you can more easily multitask. Use 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 vertically 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, 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 like My Files and Samsung Health have been optimized for a large screen, allowing you to organize and understand insights at a glance. It’s also the first Galaxy foldable to have standalone Samsung DeX available, so you can set up a full working environment from virtually anywhere. Go to the Quick Settings panel and select DeX for an advanced work setup, and access up to four workspaces that can each run five apps simultaneously. From there, review and edit a meeting presentation in one workspace and quickly navigate to another to chat with friends and shop online. Add a secondary screen in Extended Mode, which enables a dual-screen experience with an external monitor. Easily drag and drop apps across screens and work across both screens with desktop efficiency. You can also add a Bluetooth mouse and keyboard (sold separately) to create portable workstation for complex projects or creative designs.
Of course, the Galaxy Z TriFold comes loaded with Galaxy AI and features like Photo Assist, including Generative Edit and Sketch to Image. Compare before and after edits side by side, while Browsing Assist can provide quick summaries or translations. Gemini Live on Galaxy Z TriFold is enhanced with multimodal AI that understands what you see, say, and do. Seamlessly speak contextual questions and get answers without having to switch among apps for high level multitasking. Using the bigger screen, show a room, a shopping site, and paint swatches, and it will provide a custom recommendation. With screen or camera sharing on Gemini Live, you can ask questions about what you are viewing to get real-time assistance and insights.
The large screen is great for watching videos, movies, and gaming as well. For an extended YouTube experience, you can now watch a video and read the comments side-by-side. Minimized creasing on the device keeps content seamless and uninterrupted. Once closed, it easily slides back into a pocket. The Dynamic 2X AMOLED cover screen boasts a refresh rate of up to 120 Hz and up to 2,600 nits brightness, 1,600 nits with the main screen. Vision Booster optimizes colour and contrast in any lighting.
The Samsung Galaxy Z TriFold will be available in Korea on December 12, 2025 followed by other markets, including China, Taiwan, Singapore, and the UAE. It will be available in the U.S. in Q1 2026; there’s no word on Canadian availability.
