Tecno Unveils World's Slimmest Tri-Fold Smartphone at MWC 2026: Phantom Ultimate G Fold
July 17, 2025
Early images reveal a flat, crease-free main display, a cover screen on the left side, and a triple-camera setup on the back, with additional images shared by tipster Ice Universe.
Tecno plans to equip the device with a high-performance chipset and a versatile triple-camera system, along with a battery over 5,000 mAh, though detailed specifications are still under wraps.
While the large 9.94-inch display and sizable battery promise impressive performance, there are concerns about battery life and durability, especially given the device's unique hinge design.
The Phantom Ultimate G Fold's introduction sparks questions about the future of foldable technology amid rising competition from brands like Samsung and potentially Apple, as design and thickness become critical factors.
Tecno is set to unveil the Phantom Ultimate G Fold, a tri-fold smartphone with a unique inward-folding design that minimizes screen exposure when closed, differing from traditional Z-style foldables.
This innovative device features a nearly 10-inch main display and an additional exterior screen, promising enhanced functionality and versatility.
The Phantom Ultimate G Fold will be showcased at Mobile World Congress 2026, though details about pricing and release dates remain undisclosed.
Despite its slim profile, the phone packs flagship features, including a high-performance chipset, a triple-camera system, and a large battery exceeding 5000mAh.
A custom-engineered dual-hinge system allows for gapless folding and multi-angle use, enabling the device to function as a mini-workstation in a partially folded state.
When fully unfolded, the device offers a seamless, crease-free display that transitions smoothly from a smartphone to a tablet, ideal for multitasking and media consumption.
Remarkably, the device measures only 3.49mm in thickness when unfolded, making it the slimmest tri-fold smartphone on the market, even thinner than competitors like Huawei and Samsung.
The hinge system is versatile, capable of holding various angles, and the overall design aims to be the thinnest tri-fold device, setting a new industry standard.
