Samsung has officially launched the Galaxy Z Trifold, its first smartphone that folds twice to reveal a massive 10-inch display, the largest screen ever on a Galaxy phone. Announced December 2, 2025, this triple-folding device challenges Huawei’s Mate XT while bringing Samsung’s decade of foldable expertise into a new category that balances tablet-sized productivity with pocket-friendly portability.
What Is the Galaxy Z Trifold?
The Galaxy Z Trifold is Samsung’s answer to the growing tri-fold smartphone market, using an inward-folding design that protects the main display when closed. Unlike traditional foldables that open once, this device unfolds twice transforming from a standard 6.5-inch smartphone into a 10-inch workspace roughly equivalent to three side-by-side 6.5-inch phones. Samsung designed it for power users who need tablet-level multitasking without carrying a separate device, targeting mobile professionals, content creators, and early adopters willing to embrace cutting-edge form factors.
The device will first launch in South Korea on December 12, 2025, followed by China, Taiwan, Singapore, the UAE, and the United States. Samsung is positioning this as a limited market test to gather real-world feedback on durability, hinge mechanics, and software optimization before potential broader commercialization.
Design and Build Engineering
Samsung engineered the Galaxy Z Trifold with two differently sized hinges using a dual-rail Armor FlexHinge structure, the most advanced hinge system Samsung has created. This dual-hinge design compensates for varying weight distribution across the three panels, creating smoother folding action despite the complexity of a multi-fold mechanism. The hinge structure allows the screen panels to meet with minimal gap, enabling the device to fold down to just 12.9mm thickness when closed.
At its thinnest point, the unfolded device measures only 3.9mm (excluding the camera bump), achieved through material optimization including titanium hinge housing and an Advanced Armor Aluminum frame. The frame prevents the internal screens from contacting each other during folding, while a ceramic-glass fiber-reinforced polymer back panel adds crack resistance without bulk. The front cover uses Corning Gorilla Glass Ceramic 2 for scratch protection.
Samsung applies rigorous quality control uncommon in smartphones: every unit undergoes CT scanning of the flexible printed circuit board to verify manufacturing accuracy, plus laser scanning to confirm all internal components are mounted at precise heights. However, the device carries only IP48 water resistance adequate for brief freshwater submersion up to 1.5 meters but not recommended for pool or beach use, and offers no sand resistance.
Display Technology Breakdown
The centerpiece is a 10-inch QXGA+ (2160×1584) Dynamic AMOLED 2X main display with 269 ppi pixel density and 1600 nits peak brightness. Samsung applied a reinforced overcoat to a shock-absorbing display layer specifically engineered for the stress of dual-folding, with minimized crease visibility compared to earlier foldables. The screen supports a 120Hz adaptive refresh rate (1-120Hz) for smooth scrolling and battery efficiency.
When folded, users interact with a 6.5-inch FHD+ (2520×1080, 21:9 aspect ratio) cover display delivering 422 ppi and an impressive 2600 nits peak brightness brighter than the main screen and most flagship phones. This cover display also features 120Hz adaptive refresh and Dynamic AMOLED 2X technology with 100% mobile color volume in the DCI-P3 color range. Both displays use Vision Booster technology to optimize color and contrast in varying lighting conditions, crucial for outdoor visibility.
Performance and Hardware Specs
The Galaxy Z Trifold runs on the customized Snapdragon 8 Elite Mobile Platform for Galaxy built on 3nm process technology, Qualcomm’s most powerful mobile chip. Samsung pairs this with a standard 16GB of RAM across both storage configurations (512GB and 1TB), with no microSD card slot for expansion. This RAM allocation enables the device’s signature multitasking capability: running up to 20 apps simultaneously across four Samsung DeX workspaces.
The device runs Android 16 with One UI 8 out of the box, making it one of the first smartphones shipping with Android 16. Connectivity includes 5G, Wi-Fi 7 (requiring compatible router and network), Bluetooth 5.4, and dual SIM support via nano-SIM plus eSIM. The device weighs 309g heavier than standard phones but lighter than carrying a phone plus tablet.
Camera System Details
Samsung equipped the Galaxy Z Trifold with a 200MP wide-angle main camera featuring Quad Pixel AF, optical image stabilization (OIS), F1.7 aperture, and 0.6μm pixel size. The sensor uses an Adaptive Pixel Sensor enabling 2x optical quality zoom without a dedicated telephoto lens, though Samsung also includes a separate telephoto camera. The rear array includes a 12MP ultra-wide camera (F2.2, 120° field of view, 1.4μm pixels) and a 10MP telephoto with 3x optical zoom, OIS, and F2.4 aperture.
Samsung’s “Space Zoom” technology extends to 30x digital zoom combining the 3x optical telephoto with AI Super Resolution processing, though image quality degrades beyond 3x. For selfies and video calls, the device houses two separate 10MP cameras: one embedded in the cover screen (F2.2, 85° FOV) and another in the main screen (F2.2, 100° FOV for wider group selfies when unfolded). Video recording supports 8K at 30fps, 4K at 60fps, and 1080p up to 240fps with gyro-EIS stabilization plus 10-bit HDR and HDR10+.
Battery and Charging
Samsung installed a 5,600mAh three-cell battery system, the largest battery in any Samsung foldable phone. The three-cell design places one battery in each of the device’s three panels for balanced weight distribution and power delivery. This capacity targets all-day endurance despite the power demands of a 10-inch 120Hz display and flagship processor.
Charging speeds reach 45W via wired Super-Fast Charging 2.0, delivering approximately 50% charge in 30 minutes using Samsung’s 45W adapter and 3A USB-C cable. Wireless charging tops out at 15W Fast Wireless Charging 2.0 (WPC Qi compatible), plus the device supports Wireless PowerShare for reverse charging other devices like Galaxy Buds or Galaxy Watches. Actual charging speeds and battery life vary based on usage patterns, network conditions, and settings.
Samsung DeX and Productivity
The Galaxy Z Trifold becomes the first mobile phone to offer standalone Samsung DeX without requiring an external display. Users activate DeX through the Quick Settings panel, transforming the 10-inch screen into a desktop-like computing environment. Samsung DeX on the Z Trifold supports up to four separate workspaces, each capable of running five apps simultaneously theoretically enabling 20 concurrent applications across multiple desktops.
For expanded productivity, Extended Mode allows users to connect an external monitor as a secondary display, enabling drag-and-drop functionality between the phone and monitor for true dual-screen desktop efficiency. Adding a Bluetooth keyboard and mouse creates a portable workstation capable of handling complex projects Samsung markets toward architects, designers, and mobile professionals. Certain apps may not run in DeX mode or require separate licenses, and wireless DeX connection works only with Miracast-compatible TVs (Samsung recommends its Smart TVs from 2019 onward).
The standard multitasking experience without DeX remains impressive: users can run three portrait-oriented apps side-by-side, resize windows for optimal viewing, or rotate the device vertically for focused document review. The Taskbar along the bottom edge provides quick access to recently used apps, and apps optimized for large screens include My Files and Samsung Health.
Galaxy AI Integration
Samsung built Galaxy AI features throughout the Z Trifold experience, requiring Samsung Account login for most AI capabilities. Photo Assist includes Generative Edit for removing unwanted objects and Sketch to Image for converting rough drawings into polished images both tools benefit from the large canvas for detailed editing. The expansive screen enables side-by-side before/after comparisons when editing photos, a workflow improvement over smaller phones.
Browsing Assist in Samsung Internet provides instant webpage summaries and translations, useful when researching across multiple tabs. Gemini Live receives special optimization for the Z Trifold with multimodal AI that understands visual input from the camera plus spoken queries. Users can share their screen or camera feed with Gemini Live for contextual assistance for example, showing it a room, a shopping website, and paint swatches to receive custom interior design recommendations.
Galaxy AI feature availability varies by region, OS version, device model, and carrier. Samsung makes no guarantees regarding accuracy, completeness, or reliability of AI-generated outputs.
