Samsung Galaxy Z TriFold just announced — everything we know so far

Just when we all thought Samsung was done rolling out phones in 2025, the company officially announced what’s arguably the most ambitious phone release this year — the Galaxy Z TriFold. Luckily it won’t be long before it’s launched, with the foldable debuting in South Korea first on December 12. Launches in China, Taiwan, Singapore, and the UAE will follow.

There’s no exact date for a U.S. release just yet, but Samsung says that it’ll arrive during the first three months of 2026. No price has been revealed yet.

The Galaxy Z TriFold launch figures to be a big deal, as a potential best phone contender when you take into consideration how it aims to blend the tablet and phone form factors together. Here’s everything we know about the Galaxy Z TriFold.

Super thin, incredibly large 10-inch main display

You could say that the Galaxy Z TriFold results from more than a half-decade of Samsung fine-tuning the design and engineering of its best foldable phones such as the recent Galaxy Z Fold 7 and Galaxy Z Flip 7 releases What’s really impressive about the Galaxy Z TriFold’s design is that it’s thinner than either the Galaxy S25 Edge and iPhone Air, measuring at an astonishing 3.9mm at its thinnest point when opened. Those ultra-thin phones measure 5.8mm and 5.64mm, respectively.

Even with this impressive thinness, Samsung manages to cram a 6.5-inch outer display onto the Galaxy Z TriFold, which matches the Galaxy Z Fold 7's cover screen. But what makes the Galaxy Z TriFold a step uo is how it unfolds to reveal a massive 10-inch Dynamic 2X AMOLED display. This easily dwarfs the 8-inch main display in the Z Fold 7.

You’re literally carrying a tablet with this, which is made better by the fact that the TriFold's screen boasts a refresh rate up to 120Hz. It’ll be interesting to see how bright the display gets, but Samsung claims that the main display reaches a peak brightness of 1,600 nits — while the main panel can get up to 2,600 nits.

The advantage of such a massive display in a pocket-sized device should be evident when it's time to multitask. When opened, the Galaxy Z TriFold will offer the equivalent of having three 6.5-inch phones running side-by-side, according to Samsung. You'll be able to resize apps to make one of the three apps you're running simultaneously more prominent than the others. You can also hold the TriFold vertically for a deeper look at documents and drawings.

When watching YouTube, you can show video and comments side-by side. And Samsung is promising a minimal crease where the phone folds, addressing a long-standing complaint about foldables.

Design and durability

Samsung has turned to an inward-folding design for the Galaxy Z TriFold, which the phone maker says will protect the device's inner display. A folding mechanism allows the TriFold to close precisely, with users receiving on-screen alerts and vibrations if they start to fold the phone incorrectly.

The phone relies on two differently-sized hinges, building upon the Armor FlexHinge introduced with this year's Galaxy Z Fold Z. The different sizes allow for a stable fold that minimizes the gap where the screen panels meet.

Samsung used Advanced Armor Aluminum for the TriFold's frame to bolster its rigidity. The back of the device features ceramic glass to withstand bumps and bruises of daily use. Still, with durability being a big concern for users who've resisted foldable phones up until now, you can imagine that the durability of the Galaxy Z TriFold will be under scrutiny when the phone finally arrives.

Other Galaxy Z TriFold specs

The Galaxy Z TriFold runs on a Snapdragon 8 Elite chipset customized for Galaxy phones. That matches the silicon used by both the Galaxy Z Fold 7 and Galaxy S25 lineup. Qualcomm has since announced the more advanced Snapdragon 8 Elite Gen 5, but that's not expected to reach Samsung devices until next year's Galaxy S26 models debut.

As for battery, Samsung says the 5,600 mAh three-cell power pack is the largest to ever grace a Samsung foldable. There's a cell in each of the TriFold's three panels for balanced power supply. The phone supports 45W charging speeds.

A 200Mp main camera highlights the rear camera array, which also features 12MP ultrawide and 10MP telephoto lenses. The latter supports a 3x zoom. Both the main screen and the cover display offer cutouts for 10MP cameras, matching the setup on the Galaxy Z Fold 7.

Samsung's push into AI features continues with the Galaxy Z TriFold, with current tools like Photo Assist, Generative Edit and Sketch to Image supported here. You'll also get Gemini Live support with the assistant able to see what you see. To that end, Gemini takes advantage of the TriFold's larger screen to offer design advice when you show it a room, paint swatches and shopping sites with furniture.

Over on the productivity side of things, it’s the first phone inSamsung’s lineup to feature a standalone DeX mode with access to up to four workspaces with each one capable of running up to five apps at the same time. This sounds incredible, but it’ll be intriguing to see it in action. Regardless, it would essentially take the experience mobile by offering users that desktop like interface anywhere they go.

Galaxy Z TriFold outlook

The big question is how much the Galaxy Z TriFold will cost. Presumably, that info will come out as we get closer to the December 12 launch date in South Korea. Even then, we may have to wait for a U.S. price, though we'd expect this phone will top the $1,999 starting price for the Galaxy Z Fold 7.

Foldable phones have yet to go mainstream, as the high price, compromised battery life and limited use cases have kept current models from catching on. We'll soon see if a larger display in a more portable device moves the needle any.
