Samsung Unveils World’s First Tri-Fold Phone: Galaxy Z TriFold with 10-inch Screen
In a landmark move for the smartphone industry, Samsung has unveiled the world’s first commercially available tri-fold smartphone, the Galaxy Z TriFold. This groundbreaking device pushes the boundaries of form and function, transforming from a compact phone into a large 10-inch tablet, blurring the lines between mobile devices and portable productivity tools.
The Engineering Marvel: A New Hinge for a New Shape
The core innovation lies in its unique folding mechanism. Samsung has introduced a new “Armor FlexHinge” system built on a dual-rail structure with two differently sized hinges. This complex engineering is designed to manage the uneven weight distribution of three panels, promising a smooth, stable, and reliable folding action—a critical challenge for a device of this design.
