Samsung is taking foldables to the next level with the Galaxy Z TriFold, a multi-fold smartphone that opens into a 10-inch workspace, runs full desktop-like DeX, and packs the most powerful hardware ever in a Samsung foldable.

Samsung just dropped its most ambitious foldable device so far: the Galaxy Z TriFold, a triple-folding smartphone that transforms into a 10-inch mini-tablet. Yes — it folds twice. And yes — it still fits in your pocket.

After more than 10 years of playing (and winning) in the foldables game, Samsung is clearly flexing. The TriFold is meant to show off everything the company has learned about bending glass, rethinking mobile design, and now, building AI-first hardware.

“Samsung’s relentless pursuit of new possibilities continues,” said TM Roh, who heads Samsung’s Device eXperience division. Translation: We’re still leading the foldable race, and here’s the proof.

A decade of foldable lessons packed into one device

The Galaxy Z TriFold is built on the idea of giving users a huge workspace without the bulk of a tablet. Thanks to Samsung’s new inward multi-fold design, the TriFold hides a 10-inch screen inside a chassis that’s just 3.9 mm thin at its slimmest point when fully opened.

Under the hood, it’s running a customized Snapdragon 8 Elite for Galaxy, a 200 MP camera, and the biggest battery Samsung has ever put in a foldable — a 5,600 mAh three-cell setup spread across the device’s three panels. It also supports 45W fast charging, meaning you can quickly juice up even this much battery.

Samsung says the folding mechanism is engineered to perfection, complete with an on-screen alert system in case you try folding it the wrong way. Every unit even gets CT and laser scans during production to make sure every hinge, PCB, and microscopic detail is in the right spot.

Key structural upgrades include:

Armor FlexHinge system with two differently sized hinges for smoother folding

New shock-absorbing foldable display layer plus a reinforced coating

Titanium hinge housing and Advanced Armor Aluminum frame

Ceramic-glass fiber-reinforced back panel

In short: tougher, thinner, cleaner.

A Samsung phone built for serious multitasking

Once you unfold the TriFold, you’re basically holding a screen equivalent to three 6.5-inch phones side by side. Samsung designed the UI to match that power — multitasking is kind of the whole point.

You can run up to 3 apps in portrait at once, resize windows however you want, review documents vertically, drag-and-drop across apps effortlessly, and pull up recent apps instantly via the bottom-right Taskbar.

Apps like Samsung Health and My Files are also optimized for the bigger canvas.

And here’s the major flex: The TriFold is the first phone with standalone Samsung DeX. No monitor needed — you can open full desktop-like workspaces directly on the device. But if you do want a monitor, TriFold can extend your workspace across two screens and even pair with a Bluetooth mouse and keyboard.

AI gets a major upgrade on a much bigger screen

Samsung is pushing Galaxy AI hard, and the TriFold’s screen size makes AI tools feel even more at home.

Photo Assist lets you use Generative Edit, Sketch to Image, and before/after comparisons

Browsing Assist brings instant page summaries and translations

Gemini Live (Google’s multimodal AI) now works more naturally across the whole screen—like giving interior design recommendations from what your camera or browser sees

Show it a room, a furniture website, and paint colors, and it can suggest what fits together. You can even talk to it while screen sharing or camera sharing.

Cinematic viewing in your pocket

The TriFold isn’t just a productivity machine — it’s built for entertainment too.

The massive 10-inch display makes movie watching feel tablet-like, while the outer screen uses Dynamic AMOLED 2X, up to 120 Hz refresh rate, and up to 2600 nits brightness. Main display brightness reaches 1600 nits, with Vision Booster improving outdoor visibility.

YouTube lovers will appreciate this: you can now watch a video and read comments side-by-side without shrinking the window.

Despite the size, the minimized crease and slimmer profile mean it still slips easily back into your pocket.

Availability

The Galaxy Z TriFold launches on December 12, 2025, starting in South Korea, followed by China, Taiwan, Singapore, UAE, and the U.S.

It will be available at select retail stores in each market so users can actually try the triple-fold magic in person.
