Samsung is basically done playing it safe. For years, we’ve watched the Galaxy Z Fold and Z Flip dominate the "regular" foldable market, but the honeymoon phase is over. People are bored. Huawei already dropped the Mate XT—the world’s first commercial triple-foldable—and Samsung is feeling the heat. Honestly, if you’ve been following the patent filings and supply chain leaks from Samsung Display, it’s clear that the Samsung Galaxy tri-fold isn't just a lab experiment anymore. It’s a 2026 reality.
The tech is wild. Think about it. You’re carrying a phone that feels roughly like a thick S24 Ultra, but it unfolds twice to become a 10-inch tablet. That’s not just a "big phone." That’s a legitimate laptop replacement that fits in your pocket.
The "Flex S" and "Flex G" Reality
Samsung Display has been showing off prototypes at CES for years. They have two main designs: the Flex S and the Flex G. The Flex S folds in an "S" shape (shocker, right?), where one part of the screen stays exposed as your phone display. The Flex G is more like a wallet; it folds inward twice to protect the glass. From what we're hearing from supply chain analysts like Ross Young, Samsung is leaning toward a design that prioritizes screen real estate without making the device as thick as a brick.
It’s hard to make these things thin. Really hard.
When you fold a screen three times, you have three layers of OLED, three layers of structural backing, and two separate hinge mechanisms. If each section is 5mm thick, you’re looking at a 15mm slab in your pocket. For context, a standard iPhone is about 7.8mm. You’re carrying two iPhones. But the payoff? You get a 16:10 or 3:2 aspect ratio that actually makes sense for multitasking. No more "square-ish" screens that letterbox every YouTube video you try to watch.
Why Does a Samsung Galaxy Tri-Fold Even Matter?
You might ask, "Who actually needs this?"
Most people don't. But if you’re a power user, the current Z Fold 6 feels... cramped. It’s great for a quick spreadsheet check, but try editing a 4K video or running three apps side-by-side. It’s tight. A tri-fold design expands the horizontal axis. It changes the math. Samsung’s mobile lead, TM Roh, has hinted repeatedly that the company is looking for the "next big form factor," and with the tablet market stagnating, merging the phone and the tablet into a single pocketable device is the only logical move left.
Samsung has a massive advantage over Huawei here: Software. One UI is already the best foldable software on the planet. Taskbars, window snapping, and S-Pen support are baked in. Adding a third panel isn't just a hardware challenge; it’s a UI challenge. Samsung’s "App Continuity" feature will need to handle three different states: closed, half-open, and fully expanded.

The Durability Elephant in the Room
Let's be real. Folding screens are still fragile.
We’ve seen the "crease" improve, but it’s still there. With a Samsung Galaxy tri-fold, you now have two creases. That’s two points of failure. Samsung has been working on something called "integrated UTG" (Ultra Thin Glass) that is supposedly more impact-resistant. They’re also reportedly using a new hinge lubricant that doesn't gunk up after 100,000 folds.
Durability isn't just about the screen. It's about the dust.
A "Z-fold" (the S-shape) leaves one-third of the main display exposed at all times. If you drop it on the sidewalk, there’s no outer "cover screen" to take the hit—you’re hitting the actual foldable panel. This is why some insiders think Samsung might go with an inward-folding "G" design first, even if it means needing an extra screen on the outside. It's a trade-off between "cool" and "don't-break-on-day-two."
What Most People Get Wrong About the Price
You’re going to see headlines saying this phone will cost $3,000.
Maybe.

But Samsung knows that $3,000 is a death sentence for a mass-market product. The Huawei Mate XT launched at a staggering price point in China, but Samsung has the benefit of scale. They own the factory that makes the screens. They don't have to buy them from BOE or LG. While the Samsung Galaxy tri-fold will definitely be a "Luxury" or "Ultra" tier product, don't be surprised if they try to land it closer to $2,100 to $2,400. Still expensive? Yes. But it’s the price of being an early adopter.
The battery is another weird engineering hurdle. You can't just put one giant battery in the middle; it would make the hinge impossible. Samsung has to use three separate battery cells, one in each "wing" of the phone, and then use a specialized controller to drain them equally so the phone doesn't get unbalanced or overheat.
The Competitive Landscape
Apple is nowhere. They’re still trying to figure out a clamshell foldable that doesn't crack. Google is iteration-focused with the Pixel Fold. This leaves the "ultra-premium" experimental space wide open for Samsung.
- Display Tech: Samsung Display M14 organic materials (the same stuff in the S24 Ultra) will likely be used to ensure the screen is bright enough to be seen outdoors, even with the extra layers of plastic and glass.
- Camera Compromises: Expect the cameras to be "good," not "Ultra-level." There just isn't enough depth in a 5mm chassis to fit a 10x periscope zoom lens. You're trading camera glass for screen glass.
- Weight: This will be a heavy device. Likely over 300 grams. If you wear loose gym shorts, this phone is going to try to pull them down.
Honestly, the Samsung Galaxy tri-fold is for the person who lives on their phone. If you're a trader, an editor, or someone who travels without a laptop, this is the holy grail.

How to Prepare for the Tri-Fold Era
If you're thinking about waiting for this device instead of buying a Z Fold 6 or S25 Ultra, keep a few things in mind. First, the first generation of any Samsung foldable is a "beta test." Remember the original Galaxy Fold with the screen protector people peeled off? Yeah. Expect some growing pains.
Second, check your insurance. A screen replacement for a tri-fold is going to be eye-watering.
The Samsung Galaxy tri-fold represents a shift from "mobile-first" to "mobile-only." We're moving toward a world where the device in your pocket is literally the only computer you need. It connects to a monitor via DeX for desktop work, it’s a tablet for movies, and it’s a phone for everything else.
Actionable Steps for Potential Buyers
- Track the "Flex" Branding: Samsung recently trademarked "Galaxy Z Extra" and "Galaxy Tri-Fold" in various regions; keep an eye on these specific names for official announcements.
- Assess Your Workflow: If you find yourself constantly wishing your current foldable was wider rather than taller, the tri-fold is specifically designed to fix that "narrow" cover screen feeling.
- Wait for the Hinge Reveal: The "dual-hinge" is the most complex part of this phone. Before buying, wait for independent teardowns (like JerryRigEverything) to see if Samsung has actually solved the debris entry problem.
- Monitor the Software: Watch for One UI 7.1 or 8.0 updates that mention "multi-pivot" support, as this is the clear signal that the hardware is ready for launch.
The move to three panels isn't just a gimmick. It’s the final form factor of the smartphone. Once we hit a 10-inch pocketable screen, there’s nowhere else to go but holograms or AR glasses. Samsung is betting the house that you want that 10-inch screen today. Based on the way the market is shifting, they’re probably right.
