Tecno Phantom Ultimate G Fold Unveiled: The World’s Thinnest Tri-Fold Smartphone with a Massive 9.94-Inch Display
The foldable smartphone space just got more exciting. After Huawei pioneered the tri-fold design with its Mate XT series and Samsung teased its upcoming Galaxy Z TriFold, Tecno has now revealed its own ambitious tri-fold concept: the Tecno Phantom Ultimate G Fold. This sleek device promises to be the world’s thinnest tri-fold smartphone and features a large, spectacular 9.94-inch display that folds inward.
The Phantom Ultimate G Fold builds on Tecno’s expertise showcased in the Phantom Ultimate 2 — a concept phone that made waves at IFA 2024. Now, the company is pushing boundaries with a foldable that blends innovative engineering, premium materials, and a user-friendly design.
Unlike many foldables that fold outward, the Phantom Ultimate G Fold folds inward in two sections, safely enclosing the main display to offer better protection from scratches and damage. This inward tri-fold layout is supported by a dual-hinge system:
-
on the right side
-
that folds over twice
This advanced hinge design allows gapless folding, giving the phone a compact and secure closure while actively protecting the display.
The tri-fold design opens to reveal a stunning 9.94-inch screen—perfect for multitasking, media consumption, and gaming. When folded, users can rely on a separate cover display for everyday smartphone functions without needing to unfold the device. Plus, the hinge system supports multi-angle hovering, turning the device into a flexible mini workstation, ideal for video calls, presentations, and hands-free use.
Tecno claims its Phantom Ultimate G Fold is the thinnest tri-fold smartphone on the market:
-
: 11.49mm
-
: just 3.49mm
These measurements surpass competitors, delivering an impressively slim form factor without compromising strength or durability.
To achieve this, Tecno uses:
-
2000MPa ultra-high-strength steel in the hinge mechanism for durability and smooth folding
-
A 0.3mm titan fiber back panel, keeping weight down and sturdiness up
This combination allows a sleek design that’s built to last.
Despite being a concept device, the Phantom Ultimate G Fold includes flagship-grade hardware:
-
Powerful high-end chipset capable of handling all your apps and games seamlessly
-
An advanced triple-camera setup to capture stunning photos and videos
-
A battery capacity exceeding 5,000mAh to keep you powered through long days
The Tecno Phantom Ultimate G Fold is a concept phone, which means it’s primarily a prototype designed to showcase futuristic technologies and innovative design ideas that might influence future mainstream devices.
-
Not intended for commercial sale—these phones are usually for displaying tech possibilities and gauging consumer interest.
-
Tecno has confirmed it will present the Phantom Ultimate G Fold at MWC 2026, where enthusiasts and industry insiders can get a closer look.
With Huawei already setting the pace with the Mate XT series and Samsung gearing up with the Galaxy Z TriFold, Tecno’s entry signals rising competition in the tri-fold segment. Tecno’s focus on making the thinnest and most durable tri-fold phone could appeal to consumers looking for elegance combined with advanced functionality.
Conclusion: The Phantom Ultimate G Fold — A Bold Vision for the Future of Foldables
Tecno’s Phantom Ultimate G Fold concept highlights what foldable phones might look like in just a few years: incredibly thin, durable, and packing a giant display inside a surprisingly compact body. Its inward fold, innovative hinge technology, and premium design make it a standout in a rapidly evolving smartphone market.
While it remains to be seen how much of this concept reaches final production, it’s clear that foldable technology is advancing at a fast pace—and Tecno is firmly in the game.
