Samsung is officially announcing the Z TriFold, its much-anticipated foldable with not one, but two hinges. It’ll launch first in Korea on December 12th, with a US launch planned for the first quarter of 2026. There’s no price just yet, but if a phone with one hinge costs $2,000, you should probably start saving your pennies nickels for this one.
The TriFold’s inner screen measures 10 inches on the diagonal, with a 2160 x 1584 resolution and a 120Hz adaptive refresh rate that goes all the way down to 1Hz. That’s a lot of screen. You can run three apps vertically side by side on it, and even use Samsung’s DeX desktop environment in a standalone mode without a separate display. On paper, the TriFold’s outer screen looks a lot like the one on the Z Fold 7. It’s a 6.5-inch 1080p display with a 21:9 aspect ratio.

Each of the TriFold’s three panels has a slightly different thickness. The center panel is the thickest at 4.2mm, and it houses a USB-C port on the bottom edge. The thinnest panel measures just 3.9mm thick, including a physical SIM tray, and the other panel is 4.0mm thick. Those two sides fold inward over the center panel, unlike Huawei’s Mate XT, which folds in a Z shape and uses part of the inner screen when folded.
The TriFold measures 12.9mm thick when it’s folded — 4.7mm thicker than a Samsung Galaxy S25 Ultra. It’s also thicker than a Z Fold 7, which is 8.9mm when you fold it, but it’s not far off the previous Z Fold 6 which is 12.1mm folded.
Although it folds differently, the Z TriFold is pretty close in size and weight to Huawei’s Mate XT and most recent XTs. The Z TriFold is just a little thicker when folded — 12.9mm versus 12.8mm — and weighs 309 grams compared to the 298g XT.
The back panel is a “ceramic-glass fiber-reinforced polymer” designed to resist cracking. The device’s hinges are two different sizes, both with a dual-rail design protected by a titanium housing. Like Samsung’s other foldables, the TriFold is rated IP48 — fully water resistant, but not dust-tight.
