The Samsung Galaxy Z TriFold and Huawei Mate XT series take completely different approaches. Samsung adopts a dual‑screen “G‑shaped” folding design, where the flexible large display is protected inside when folded, naturally offering more protection than Huawei’s solution and giving it a significant advantage in drop resistance.

The device weighs 309g, close to a can of soda, and measures 12mm thick when fully folded. At the same time, you can sense Samsung’s consistent premium feel in foldables: the craftsmanship is meticulous, the edges don’t feel sharp in the...
