Samsung Galaxy Z TriFold: Details
According to Samsung, the Galaxy Z TriFold introduces a new display architecture built around a screen that folds twice. The panel uses a reinforced top layer and a shock-absorbing structure to improve durability. The device also features an updated Armor FlexHinge system, with two differently sized hinges using a dual-rail design. This allows both side panels to fold inward over the centre panel, forming a compact, smartphone-like shape when closed with minimal gaps.
The hinge assembly uses a titanium housing, while the frame is made from an aluminium alloy. When folded, the Galaxy Z TriFold measures 12.9mm thick, making it thicker than both the Galaxy Z Fold 7 and the Galaxy S25 Ultra. Each panel has a different thickness: the centre panel is 4.2mm and houses the USB-C port, the thinnest panel measures 3.9mm and contains the SIM tray, while the third panel is 4.0mm thick. The device weighs 309g.
