After months of leaks, rumors, and behind-glass teasers, Samsung confirmed pricing, features, and launch details, while new hands-on footage gives us the clearest look so far at how this sci-fi device actually works.

A New Era of Foldables Begins
The Samsung Galaxy Z TriFold is Samsung’s boldest attempt to push foldables beyond the traditional book-style design. Unlike the Galaxy Z Fold 7, the TriFold uses two hinges, allowing the screen to expand into a 10-inch tablet-like display. This instantly positions it as one of the most advanced consumer mobile devices ever produced.
samsung galaxy z trifold release date
Samsung will launch the TriFold first in South Korea on December 12, priced at 3,594,000 won, roughly $2,400 USD. Based on Samsung’s previous pricing differences between Korea and the US, experts estimate that the US retail price may land around $2,800.
Other markets confirmed include China, Taiwan, Singapore, and the UAE, with more regions expected in early 2026.
Samsung Galaxy Z TriFold Design
A new hands-on video from SuperSaf provides the first detailed look at how the TriFold actually opens and closes.
How the Samsung Galaxy Z TriFold Folds
- The phone opens from the back side.
- The panel containing the camera opens first.
- A second hidden panel unfolds afterward, revealing the full 10-inch AMOLED display.
- The inner display is disabled until fully unfolded, preventing accidental input.
Samsung built software logic to prevent user error. If someone tries to close it incorrectly — such as reversing the order of the hinges — the phone displays a full-screen warning, paired with strong vibrations.
Samsung Galaxy Z TriFold Display Creases
Due to the dual-hinge design, the device naturally includes two creases. According to first-look video impressions, the creases resemble the Galaxy Z Fold 7’s crease in depth and visibility, but now appear twice, one for each hinge mechanism.
First Samsung Phone With On-Device DeX
One of the most impressive upgrades is that the Galaxy Z TriFold becomes the first Galaxy smartphone to support DeX directly on its own display.
No monitor required.
With the tablet-sized 10-inch screen, users can:
- Run a full desktop-like interface
- Connect a mouse and keyboard
- Use multiple overlapping windows
- Open up to four workspaces with five apps each (up to 20 apps simultaneously)
This elevates the TriFold from a fancy foldable to a potential laptop replacement.
Multitasking Like Never Before
When fully unfolded, the TriFold operates as the equivalent of three 6.5-inch bar-style screens side by side.
This enables:
- Three full apps running independently
- More efficient split-screen productivity
- Better gaming and media experiences
- Smooth switching between phone and tablet modes
This flexible design unlocks features not possible on traditional foldables.
Durability: Reinforced Hinges and Premium Protection
Samsung is aware of skepticism surrounding foldable durability — and this device doubles the complexity. So the company has emphasized structural improvements, including:
- Reinforced aluminum frame
- Stronger dual-hinge system
- Upgraded flexible display layers
- Internal protections against folding stress
Samsung is also offering buyers a one-time 50% discount on display repair, acknowledging the phone’s engineering complexity.
Samsung Galaxy Z TriFold Battery Capacity and Performance
The Galaxy Z TriFold includes a large 5,600mAh battery, the biggest battery Samsung has ever used in a foldable. Samsung says this allows:
- Up to 17 hours of video playback with the screen fully open
- Longer productivity and entertainment sessions
- Potential multi-day light usage
Though Samsung did not reveal mixed-use battery estimates, the capacity is significantly higher than the Fold 7’s.
Galaxy AI Features Included
The TriFold includes Samsung’s full suite of Galaxy AI tools, such as:
- Generative Edit
- Photo Assist
- Live Translate
- Writing Assist
- Notes and document enhancements
Buyers also get a 6-month Google AI Pro subscription trial, adding more value to the premium purchase.
Samsung’s Strategy: A Tech Showcase Before Apple’s Foldable Arrives
Industry analysts believe Samsung’s goal with the TriFold is not to sell millions of units, but to demonstrate foldable leadership ahead of Apple’s expected folding iPhone in late 2026.
Counterpoint Research notes:
- TriFold units will ship in limited volumes
- Foldables represent only 2.5% of the global smartphone market
- Samsung currently holds 64% of all foldable shipments
- The TriFold acts as a technology pilot, not a mass-market device
This explains why initial availability may be restricted and why Samsung has avoided revealing full Western launch plans.
Competitive Market: Huawei Already Has a TriFold
Huawei launched the Mate XT and Mate XTs earlier, proving that trifold designs are technically possible. However:
- Huawei’s approach uses a Z-shaped outward fold
- Samsung folds inward from two sides
- Huawei lacks Google-powered app compatibility
This means Samsung’s version is more globally practical and better integrated with mainstream Android apps.
Will the Samsung Galaxy Z TriFold Launch in the US?
Samsung states that the device will launch in the US in Q1 2026, despite earlier reports suggesting it might skip Western markets.
However, sales volume is expected to be extremely limited due to:
- High production costs
- Niche demand
- Complex repairs
- Premium pricing
Still, the US launch will be crucial for positioning Samsung as the undisputed leader in the foldable space.
What Comes in the Box
Samsung surprisingly includes:
- A premium protective case
- A charging brick (rare in 2025)
- Documentation and cables
A kickstand case will also be sold separately.
Conclusion: The Most Ambitious Foldable Ever Made
The Samsung Galaxy Z TriFold is not just another foldable. It’s a major step forward in smartphone engineering, blending:
✔ A triple-screen experience
✔ A 10-inch tablet display
✔ The first on-device DeX desktop environment
✔ Improved durability
✔ Industry-leading AI features
✔ A massive battery upgrade
At an estimated $2,800 USD, it won’t be for everyone — but it redefines what a phone can be and sets the stage for the next generation of foldables, especially with Apple entering the category next year.
If Samsung can deliver long-term durability and practical usability, the TriFold may become one of the most influential mobile devices of the decade.
