The Samsung Galaxy Z TriFold is Samsung's first tri-fold smartphone — a 309g engineering marvel that unfolds from a pocketable phone into a full 10-inch tablet via two precision hinges. Launched in December 2025 at $2,899, it sold out globally within minutes of each restock before being discontinued in March 2026, with a successor already confirmed for 2027.
