Samsung Galaxy Z TriFold Unveiled: Full Specs, Features & eSIM Support
Samsung has just lifted the curtain on its most ambitious mobile innovation yet: the Galaxy Z TriFold. A three-fold smartphone that reimagines what a mobile device can be. With a massive 10-inch main screen and cutting-edge hardware, this device isn’t just a phone, it’s a productivity powerhouse in your pocket.
A New Era of Foldable Phones
Unlike traditional foldables, the Galaxy Z TriFold uses a tri-fold design with two precision-engineered hinges, allowing the device to open in stages or fully unfold for maximum screen real estate. Samsung designed this inward-folding mechanism to protect the main display while maintaining a slim, portable profile when closed.
At just 3.9 mm at its thinnest point, the Galaxy Z TriFold manages to deliver flagship-level performance without compromising durability or usability. Samsung’s most advanced Armor FlexHinge system, reinforced materials, and strict quality testing ensure smooth folding, long-term reliability, and a refined everyday experience.
Design & Display
At the heart of the Galaxy Z TriFold is its 10.0-inch Dynamic LTPO AMOLED 2X main display, featuring a QXGA+ resolution (2160 × 1584), HDR support, and an adaptive 120 Hz refresh rate. The screen is optimized for multitasking, creative workflows, and cinematic viewing, with minimized creasing for a seamless visual experience.
When folded, the device functions as a premium smartphone with a 6.5-inch Dynamic AMOLED cover display (FHD+), also running at 120 Hz. With peak brightness reaching 2,600 nits on the cover screen and 1,600 nits on the main display, visibility remains excellent even in bright outdoor conditions.
Samsung’s display expertise shines through with vivid colors, strong contrast, and Vision Booster enhancements that adapt visuals to any lighting environment.
Flagship Performance in a Multi-Fold Design
Powering the Galaxy Z TriFold is the Snapdragon® 8 Elite Mobile Platform for Galaxy, delivering top-tier performance for multitasking, gaming, and AI-driven features. The device is paired with a 200 MP camera system, designed to take advantage of the expansive screen for editing, previewing, and creative workflows.
To support all-day use, Samsung equipped the Galaxy Z TriFold with its largest battery ever in a foldable phone: a 5,600 mAh three-cell system distributed across the device’s three panels for balanced power delivery. Combined with 45 W fast charging, the device is built to keep up with demanding workdays and extended travel.
Built for Productivity, Creativity, and AI
With its expansive display, the Galaxy Z TriFold unlocks entirely new ways to work and create. Users can run three portrait-sized apps side-by-side, resize windows freely, and switch tasks instantly using an optimized taskbar. Familiar apps like My Files and Samsung Health have been redesigned to take full advantage of the larger screen.
The Galaxy Z TriFold is also the first Galaxy phone to support standalone Samsung DeX, allowing users to create a desktop-like workspace anywhere, no external PC required. With support for multiple workspaces, external monitors, and Bluetooth keyboards and mice, the device becomes a true portable workstation.
Samsung’s latest Galaxy AI features scale naturally to the 10-inch display, enhancing photo editing, content creation, browsing, and real-time assistance. Multimodal AI capabilities through Gemini Live allow users to interact seamlessly using voice, visuals, and on-screen content, all without breaking their workflow.
