The TriFold measures 12.9mm thick when folded, making it 4.7mm thicker than the Samsung Galaxy S25 Ultra and slightly thicker than the Z Fold 7 at 8.9mm, but closer in size to the Z Fold 6 at 12.1mm.

The device features a unique design allowing it to unfold twice, revealing a 10-inch Dynamic AMOLED 2X screen, which users found conducive for productivity, akin to a compact tablet rather than a smartphone.
The Galaxy Z TriFold is also integrated with advanced AI functionalities, including Galaxy AI features like Photo Assist and Sketch to Image, which captivated customers during demonstrations. The device’s sturdiness, enhanced by its new hinge system and features preventing improper folding, addresses past durability concerns associated with foldables.
The Samsung Galaxy Z TriFold boasts a 10-inch Dynamic AMOLED 2X display with a resolution of 2160 × 1584 and an adaptive refresh rate from 120 Hz to 1 Hz. This display supports Samsung DeX, enabling it to function as a standalone workstation with the capability to run three apps concurrently, enhancing productivity. Externally, it includes a secondary 6.5-inch 1080p display that mirrors the aspect ratio of the Z Fold 7’s cover screen.
The construction consists of three panels with varying thicknesses: a 4.2 mm middle section with a USB-C port, a 4.0 mm panel, and a 3.9 mm panel containing a SIM tray. When folded, the device reaches a thickness of 12.9 mm, making it bulkier than the Galaxy S25 Ultra and the Z Fold 7 yet similar in size to Huawei’s Mate XT.
Durability is addressed with a titanium-reinforced Armour FlexHinge and a dual-rail mechanism that stabilises the folding process. The hinge features a metal reinforcer for durability, while the back panel is crafted from a ceramic-glass fibre-reinforced polymer. The device has an IP48 rating, providing some resistance to water exposure, although not entirely dustproof.
Camera capabilities are impressive, including a 200-megapixel primary lens, a 12-megapixel ultrawide, and a 10-megapixel telephoto camera, supplemented by two 10-megapixel selfie cameras located on both displays. Internally, it operates on the Snapdragon 8 Elite for Galaxy chipset, paired with 16 GB of RAM, and incorporates a balanced battery configuration totalling 5,600 mAh.
The Galaxy Z TriFold, with its advanced engineering and ambitious integration of Galaxy AI, positions itself as one of Samsung’s most notable devices in recent memory, embodying a sci-fi aesthetic with practical functionality.
