Samsung has once again pushed the boundaries of mobile design with the launch of the Galaxy Z TriFold — a premium device that folds not once, but twice, to deliver the largest screen ever built into a Galaxy smartphone. After years of leadership in foldable technology, Samsung reframes what a mobile device can be: a pocketable phone, a creative canvas, and a portable workstation all in one.

A bold new form factor for the AI era

The defining idea behind the Galaxy Z TriFold is simple but revolutionary: maximize usable screen space while keeping the device slim and portable. Engineers overcame the core challenges of multi-fold devices by rethinking hinges, display layers, and internal architecture. When fully deployed, the TriFold measures only 3.9 mm at its thinnest point, yet opens to a 10-inch display — the largest ever on a Galaxy device.

Samsung positions the TriFold as a device built for today’s AI-enhanced workflows: more screen means more room for Galaxy AI features, multitasking, and creative tools that benefit from a generous canvas.

Flagship performance and photography

Performance is flagship-grade. The Galaxy Z TriFold runs on a custom Snapdragon® 8 Elite Mobile Platform for Galaxy, tuned to handle demanding games, heavy multitasking, and AI-driven features with speed and efficiency. Photo enthusiasts will appreciate the 200 MP main camera system, designed to capture highly detailed images across lighting conditions.

Massive battery, smart placement

Battery life was a major focus: Samsung fitted the TriFold with a 5,600 mAh three-cell battery, the largest yet in a Samsung foldable. The cells are distributed across the device’s three panels to ensure balanced power delivery and thermal stability. Paired with 45W Super Fast Charging, the TriFold is engineered to last a full day of intense use — streaming, editing, video calls, and more.

Durability reimagined

A triple-fold design demands new approaches to durability, and Samsung answers with several hardware improvements:

• Advanced Armor FlexHinge: Two differently sized hinges and a dual-rail structure provide smoother movement, better stability, and a minimal gap between panels.
• Reinforced display stack: A shock-absorbing layer topped with a stronger overcoat increases resistance across both folds.
• Premium materials: The hinge uses a titanium housing; the frame is built from Advanced Armor Aluminum for rigidity without unnecessary bulk; and the rear panel combines ceramic-glass fiber–reinforced polymer for crack resistance.
• Quality assurance: Each unit undergoes precision checks including CT scans of flexible circuits and laser scanning of internal components to ensure accurate assembly.

Productivity: a portable workstation

Where the TriFold truly shines is productivity. The 10-inch screen functions like three 6.5-inch displays side-by-side, allowing users to open three portrait apps simultaneously, resize windows, and hold the device vertically for document review or reading.

For desktop-class workflows, Samsung introduces standalone Samsung DeX on the phone — the first time DeX runs independently on a mobile device. Users can create up to four separate workspaces, each capable of running multiple apps at once. With Extended Mode, an external monitor can act as a second screen, transforming the TriFold into a true portable workstation when paired with a Bluetooth keyboard and mouse.

Galaxy AI: intelligent features scaled up

Galaxy AI is integrated throughout the experience and scales especially well on the TriFold’s large display:

• Photo Assist: Generative Edit and Sketch-to-Image allow creative edits on a big canvas, with side-by-side before/after views.
• Browsing Assist: Instantly summarizes web content, translates text, or surfaces key points while you research.
• Gemini Live (multimodal): Understands images, speech and user actions — ask contextual questions without switching apps, get real-time assistance during screen shares, or request design ideas simply by showing materials and photos.

Entertainment: a cinematic pocket device

The TriFold is also a media powerhouse. The expansive main display delivers an immersive viewing experience with minimal creasing, while the Dynamic AMOLED 2X cover screen offers smooth visuals at up to 120Hz and peak brightness up to 2600 nits — great for outdoor visibility even when the device is folded. Split-screen viewing is a breeze: watch video while reading comments or notes side-by-side.

Availability and launch offers

Samsung plans to make the Galaxy Z TriFold available first in South Korea on December 12, 2025, followed by launches in China, the United States, select Middle Eastern markets, and other parts of Asia.

Launch incentives include:

• A 6-month trial of Google AI Pro, which includes features like Veo-powered video generation and 2 TB of secure cloud storage.
• A one-time 50% discount on display repair for TriFold purchasers.
