Samsung Unveils Galaxy Z TriFold: A Revolutionary Triple-Fold Smartphone with Desktop-Level Features

Samsung has launched its most advanced foldable device to date, the Galaxy Z TriFold, which offers an innovative triple-fold design that opens into a 10-inch mini-tablet while remaining compact enough to fit in a pocket. This new model showcases Samsung's technological expertise developed over more than a decade in the foldable smartphone market.

TM Roh, head of Samsung’s Device eXperience division, emphasized the company’s commitment to innovation, stating, "Samsung’s relentless pursuit of new possibilities continues." The TriFold represents the culmination of years of research in flexible glass technology, mobile design, and AI-enhanced hardware.

The Galaxy Z TriFold features an inward multi-fold mechanism that delivers a large, expansive workspace without the bulk of traditional tablets. When fully opened, the device measures just 3.9 mm at its thinnest point. Powered by a customized Snapdragon 8 Elite chip, the phone includes a 200-megapixel camera system and the largest battery ever seen in a Samsung foldable phone — a 5,600 mAh three-cell battery supporting 45W fast charging for quick replenishment.

Samsung has engineered the folding system with precision, incorporating an on-screen alert that prevents incorrect folding. Each unit undergoes meticulous quality checks, including CT and laser scanning, ensuring perfect alignment of hinges and internal components.

Key structural enhancements include the Armor FlexHinge system with dual-size hinges for smoother folding, a new shock-absorbing foldable display layer protected by reinforced coatings, a titanium hinge housing paired with an Advanced Armor Aluminum frame, and a ceramic-glass fiber-reinforced back panel — all crafted to enhance durability while maintaining a slim profile.

The TriFold’s screen supports extensive multitasking capabilities, allowing users to run up to three applications simultaneously in portrait mode, resize windows freely, review documents vertically, easily drag and drop content between apps, and access recent apps quickly through a bottom-right Taskbar. Native apps like Samsung Health and My Files have been optimized for this larger display.

A major innovation introduced with the TriFold is standalone Samsung DeX, enabling a full desktop-like experience directly on the device without needing an external monitor. For users who prefer a larger setup, the smartphone can also connect to external screens and support Bluetooth mouse and keyboard inputs.

Samsung has further enhanced AI applications to complement the expansive display. Features such as Photo Assist offer Generative Edit, Sketch to Image, and before/after views; Browsing Assist delivers instant summaries and translations; and Gemini Live, Google's multimodal AI, provides contextual recommendations like interior design suggestions through real-time camera or browser inputs. The AI even supports interactive conversations during screen or camera sharing.

Beyond productivity, the TriFold is designed for immersive entertainment. Its massive 10-inch main screen utilizes Dynamic AMOLED 2X technology with a 120 Hz refresh rate and brightness levels up to 1600 nits, enhanced by Vision Booster for outdoor use. The outer display reaches up to 2600 nits brightness, perfect for watching videos and reading comments simultaneously without compromising window size.

Despite its size, the TriFold's refined hinge mechanics and minimized crease allow it to fold into a surprisingly compact device suitable for everyday pocket carry.

The Galaxy Z TriFold is set to launch on December 12, 2025, beginning in South Korea before expanding to markets including China, Taiwan, Singapore, the UAE, and the United States. Select retail locations will offer hands-on experiences to showcase the device's transformative folding capabilities.
