As excitement builds around tri-fold smartphones, Tecno is gearing up to challenge the top players in this market with its latest prototype, known as the Phantom Ultimate G Fold Concept. This device, previously mentioned in a leak, boasts a dual inward-folding design that securely hides the entire display when closed. It features a 9.94-inch flexible screen that folds twice, resulting in a folded thickness of 11.49mm. While this is noticeably thicker than the Samsung Galaxy Z Fold 7, which is currently priced at $1,999 on Amazon and measures 8.9mm, it is slightly thinner than the Huawei Mate XT Ultimate at 12.8mm. However, it’s important to note that the Z Fold 7 is not a tri-fold device.
Innovative Folding Mechanism
The folding mechanism consists of two hinges: a small waterdrop-style hinge for the first fold and a larger primary hinge that wraps the rest of the display on top. This design allows the device to close completely without any visible gaps. A self-locking feature ensures that the phone remains securely shut.
Impressive Display and Functionality
When opened, the expansive display delivers a nearly crease-free experience, resembling a tablet. Tecno claims this design supports innovative usages, such as multi-angle hovering and mini workstation configurations. Additionally, an outer screen enables the device to operate like a regular smartphone without needing to unfold it.
Durability and Performance
The phone incorporates 2000MPa ultra-high-strength steel in its hinge and a 0.3mm Titan Fiber (likely a titanium-based material) rear cover, effectively reducing weight while ensuring sturdiness. When fully extended, the device measures a slim 3.49mm in thickness.
The concept model showcases a powerful chipset, a triple camera layout, and a battery exceeding 5000mAh, although specific details are yet to be revealed. Tecno plans to present the device again at MWC 2026.
Previously, during MWC 2025, Tecno unveiled a triple-fold prototype called the Phantom Ultimate 2 Tri-Fold. You can find more information about that here.
