Samsung has taken a big step forward in mobile innovation by releasing the Galaxy Z TriFold, its first-ever tri-fold smartphone. With just two folds, it can turn from a small phone into a huge 10-inch tablet. This device, which was announced on December 2, 2025, isn’t just an evolution of the foldable category; it’s a redefinition that combines portability, powerful performance, and AI-driven productivity into one bold package. The foldable market is getting more competitive with companies like Huawei and rumors that Apple will soon join the fray. Samsung’s TriFold makes the company the clear leader in multi-panel designs.
A Design That Will Last
When you first look at the Galaxy Z TriFold, it looks like a bigger version of Samsung’s Galaxy Z Fold7. But when you open it up, the magic happens—literally. The phone has three articulated panels that are connected by two advanced Armor FlexHinges with a dual-rail structure. This lets the phone fold inward to fully protect the main display. When fully opened, it shows a huge 10-inch inner screen (253.1mm diagonal) with a 120Hz refresh rate. This lets you run three full-sized apps side by side in portrait mode without any problems. The 6.5-inch cover screen keeps things phone-like when the phone is folded, making it easy to use with one hand.
The TriFold is only 3.9mm thick when it’s open, so it focuses on being thin without losing strength. When folded, it’s 12.9mm thick and weighs 309g, which is a lot more than the Z Fold7’s 215g, but it’s still small enough to fit in a pocket. Samsung’s inward-folding mechanism has smart alerts and vibrations to stop the screen from closing incorrectly. This keeps the screen crease-free (like the Z Fold7’s) and safe through 200,000 folding cycles, which is like using it every day for five years.
The TriFold comes in a sleek Crafted Black color and has an IP48 rating for dust and water resistance, so it’s tough enough for real-world adventures.
The Best Power in a Foldable Form
The Galaxy Z TriFold has Samsung’s own Snapdragon 8 Elite Mobile Platform inside, which makes it super fast for gaming, AI tasks, and heavy multitasking. It has 16GB of RAM and storage options of 512GB or 1TB (no microSD expansion). It can do everything from editing videos to using DeX mode on the device. This is the first standalone implementation on a Galaxy phone, and it turns the 10-inch screen into a desktop workspace with a simple Quick Settings toggle.
The camera array is the same as the Z Fold7’s pro-grade setup: a 200MP main sensor with OIS and 2x optical zoom, a 12MP ultra-wide, and a 10MP telephoto with 3x optical zoom on the back. There are two 10MP front cameras, one for the cover screen and one for the main screen. This makes sure that selfies are always clear. With the next-gen ProVisual Engine, it does a great job of editing in low light and with AI.
The battery life is great, and the foldable has the biggest battery ever: a 5,600mAh three-cell system spread out across the panels for balanced power. It has 45W Super-Fast Charging (50% in 30 minutes), 15W wireless charging, and reverse wireless charging, so it should last all day even with the big screen.
The TriFold runs Android 16 with One UI 8 and has Galaxy AI built in for things like real-time translation and photo editing with Audio Eraser to get rid of noise in videos. There is no S Pen support, which is a trade-off for the thinner design.
Prices, Availability, and the Big Picture
The base model with 512GB of storage costs 3,594,000 KRW (about $2,450 USD). Samsung executives have called the TriFold a “special-edition” device to see how it does in the premium niche. It will be available in South Korea on December 12, 2025, and in the U.S. in the first quarter of 2026. After that, it will be available in China, Taiwan, Singapore, and the UAE. People who buy early in Korea get benefits like a 50% discount on display repairs. The box comes with a case, a kickstand option, and a 45W charger, which are hard to find in today’s flagship phones that come in slim packages.
What the TriFold is Important
The Galaxy Z TriFold from Samsung isn’t for everyone. Its high price and 309g weight scream “enthusiast’s delight” instead of “everyday essential.” But in a time when foldables are expected to grow because of competition from Huawei’s Mate XT and Apple’s rumored iFold, this device cements Samsung’s decade-long dominance in the foldable market. It solves the problem of portability and productivity by giving you a tablet’s canvas in a (relatively) phone-sized package.
