Samsung today introduced the Galaxy Z TriFold, its first smartphone that has three total inner display sections with two folds instead of one. The Galaxy Z TriFold features a 10-inch display when opened, and a 6.5-inch cover screen when closed, with "minimized creasing."
The device has an inward-folding design that's meant to protect the main display, and Samsung says that the "easy opening and closing" folding mechanism has been engineered with an alarm that alerts the user if it's folded incorrectly. Samsung is using a titanium Armor FlexHinge with two differently sized hinges that work together with a dual-rail structure. Samsung claims that the new design offers a smoother, more stable fold despite the varying weight across each display, plus greater durability thanks to the inclusion of a "thin piece of metal" that protects the folding mechanism.
A third of the display is 3.9mm thick when the smartphone is unfolded, though it is thicker in the area with the triple-lens camera. The main center screen is a bit thicker at 4.2mm, and the screen with the side button is 4mm. There is a reinforced overcoat over a shock absorbing display layer for better resistance, and the aluminum frame keeps the screens from making contact with one another.
There's a 5,600 mAh three-cell battery system with one battery behind each display panel. Samsung says it is the largest battery that it has used in a smartphone to date. There are three cameras at the rear of the device, including a 200-megapixel wide angle camera, a 12-megapixel ultra wide camera, and a 10-megapixel telephoto camera with 3x optical zoom. There are two 10-megapixel selfie cameras on the cover screen and the main screen.
Galaxy Z TriFold users can use three different portrait-sized apps side-by-side, resize apps in a multi-window view, watch shows in full screen, or hold the device vertically for reading. Samsung added standalone Samsung DeX, so the Galaxy Z TriFold supports up to four workspaces with five apps running simultaneously. Samsung apps have been optimized for the larger screen, as has Google's Gemini Live.
The Galaxy Z TriFold is launching in Korea on December 12, and it will expand to other markets like China, Taiwan, Singapore, and the UAE later. It will launch in the United States in the first quarter of 2026, and pricing is unknown.
