Samsung’s long-rumored tri-fold smartphone is closer than ever to becoming reality. The upcoming device has been spotted in the Bluetooth SIG certification database, signaling that an official global launch could be just around the corner.
The listing, which surfaced earlier this week, includes multiple model numbers — SM-D6390, SM-D639N, SM-D639U, SM-D639U1, and SM-D639B — suggesting that Samsung is preparing to release the device across different markets, including North America, China, and South Korea.
A Major Step Toward Launch
Bluetooth SIG certification typically appears in the final stages before a product’s public release. This means Samsung’s first tri-fold smartphone may debut sooner than expected, possibly alongside the company’s next Galaxy Z Fold and Z Flip lineup or even before its annual Unpacked event.
While official details remain under wraps, reports from industry insiders suggest that the device will feature two large folding hinges, allowing it to open into a tablet-sized display or fold into a compact smartphone form factor.
Expected Features and Design
Leaks indicate that Samsung’s tri-fold will use its latest Ultra Thin Glass (UTG) technology for durability and flexibility, combined with Bluetooth 5.3 connectivity, as confirmed by the SIG filing.
The phone is also expected to include Samsung’s signature S Pen support, multitasking features, and enhanced cooling systems to handle the increased display surface and performance load.
If the reports hold true, the device may also incorporate AI-driven optimization to seamlessly transition between folded modes, ensuring an intuitive user experience for productivity, gaming, and entertainment.
Samsung’s Edge in Foldable Innovation
Samsung has consistently led the foldable smartphone segment, and the tri-fold concept could represent the next major leap in display innovation. Industry experts believe the device will strengthen Samsung’s dominance in the foldable category — a market expected to grow rapidly in 2026 as more competitors enter the space.
Though the company has yet to confirm an official release date, the new Bluetooth certification strongly indicates that Samsung’s tri-fold smartphone could launch within months, possibly under the name Galaxy Z Flex or Galaxy Tri Fold.
Tech enthusiasts worldwide are now eagerly waiting to see how this next-generation design redefines multi-screen flexibility and mobile productivity.
