We knew it was coming. Between the years of concept devices sitting behind glass cases at CES and the relentless rumor mill, a tri-foldable was inevitable. But looking at the spec sheet for the newly announced Samsung Galaxy Z TriFold, it feels less like an experiment and more like Samsung flexing every engineering muscle it has.

The company officially unveiled its first double-folding phone today, December 2, and the headline is that it opens into a large 10-inch display.

For context, a base model Apple iPad is 10.9 inches. The Galaxy Z TriFold is effectively a full-sized tablet that collapses into a 6.5-inch smartphone you can shove into a pocket. Granted, it’s a heavy pocket; at 309g, it’s hefty compared to the 232g Galaxy S24 Ultra, but considering it replaces two devices, the math kind of works out.

When fully unfolded, the Samsung Galaxy Z TriFold is remarkably thin at 3.9mm. To pull this off, the South Korean technology giant is using a new three-cell battery system totaling 5,600mAh distributed across the panels to keep the weight balanced.

The main draw is obviously that 10-inch QXGA+ Dynamic AMOLED 2X screen. We’re looking at a 120Hz adaptive refresh rate and a peak brightness of 1,600 nits. The real utility, though, is the aspect ratio. When open, it supports three full portrait-sized apps side-by-side.

Samsung’s announcement

If you’ve ever tried multitasking on a standard Galaxy Z Fold, you know the struggle of squashed windows. The TriFold claims to fix that. You can have Discord, a web browser, and YouTube open simultaneously without any of them looking like a mobile-optimized mess.

Also, for the productivity die-hards, Samsung confirmed this is the first smartphone to support standalone Samsung DeX. You don’t need a monitor. You can just prop the unit up and use the 10-inch screen as a mini-desktop environment.

The Samsung Galaxy Z TriFold is running on the Qualcomm Snapdragon 8 Elite 5G processor, backed by 16GB of RAM. Storage options top out at 1TB. It’s clear Samsung wants this to be a “do everything” device, and it didn’t skimp on the cameras, either. While foldable cameras usually lag behind their slab counterparts, the TriFold is packing a 200-megapixel main sensor. That is S-series Ultra territory. It’s flanked by a 12-megapixel ultrawide and a 10-megapixel telephoto with 3x optical zoom.

The big question, naturally, is durability. The brand says it uses two differently sized Armor FlexHinges to manage the folding mechanics and has reinforced the screen with a new shock-absorbing layer. Samsung claims the model survives 200,000 folds. We’ll have to see how that holds up against real-world grit and pocket lint.

The Galaxy Z TriFold launches in Korea on December 12, 2025, with a global rollout to follow. We don’t have the price yet, but considering the tech inside? You might want to start saving now.
