Overview
- The Galaxy Z TriFold appeared on the Bluetooth SIG registry with model numbers SM-D6390, SM-D639U, SM-D639U1, SM-D639N, and SM-D639B.
- Industry reporting maps those codes to China, South Korea, US carrier and unlocked versions, and an international model, indicating a potential rollout beyond earlier expectations.
- Samsung previewed the tri-fold at the K‑Tech Showcase in Korea and has said the device will arrive by the end of the year.
- Leaks and patents describe a tri‑panel, dual‑hinge design with about a 10‑inch fully opened display, an ~8‑inch intermediate mode, and a ~6.5‑inch folded state, plus a three‑cell battery system and a 200MP main camera.
- Coverage continues to point to a limited initial launch with constrained production and select markets such as Korea and the UAE, while Huawei already sells tri‑fold devices.
