TECNO just dropped its latest game-changer, the PHANTOM Ultimate G Fold Concept, a tri-fold smartphone that pushes the boundaries of foldable tech. This sleek device boasts a dual-screen, inward-folding design with a massive 9.94-inch display that’s built to last.
When folded, it’s a slim 11.49mm, and when fully opened, it slims down to an incredible 3.49mm, making it the thinnest tri-fold phone out there. It’s a bold step forward in what foldable devices can achieve.
A Smarter Tri-Fold Design
Unlike typical tri-fold phones that leave their screens vulnerable, the PHANTOM Ultimate G Fold Concept uses a clever G-Style design. Its large inner screen folds inward twice, keeping it safe from scratches and bumps when not in use. A secondary cover screen handles everyday tasks, giving you the familiar feel of a standard smartphone.
The magic lies in its dual-hinge system: a smaller waterdrop hinge lets the right side of the screen fold inward smoothly, like a book, while a larger main hinge folds the rest over it. A self-locking feature ensures everything stays secure and gap-free when closed.
This setup also unlocks cool new ways to use the phone. The big hinge includes a dual-cam design that supports multi-angle hovering, letting you prop the device up partially folded for use as a mini-workstation. Fully unfolded, the 9.94-inch display is nearly crease-free, transforming the phone into a tablet-like powerhouse for multitasking or enjoying media.
Thinnest Tri-Fold with Top-Tier Features
Despite its complex tri-fold design, this phone is impressively slim at 11.49mm when folded—on par with many dual-fold phones—and a record-breaking 3.49mm when unfolded. TECNO pulled this off with cutting-edge materials like ultra-strong 2000 MPa steel for the hinge and a 0.3mm-thick Titan Fiber back cover.
Even with its slim profile, the PHANTOM Ultimate G Fold Concept doesn’t skimp on performance. It packs a high-powered chipset, a triple-camera system, and a beefy battery over 5000mAh, delivering a true flagship experience.
TECNO’s Vision for the Future
The PHANTOM Ultimate G Fold Concept is the latest in a string of bold moves from TECNO’s premium PHANTOM brand, known for blending cutting-edge tech with sleek style. Following the buzz around their ultra-thin PHANTOM ULTIMATE 2 tri-fold concept at MWC 2025, this new device doubles down on TECNO’s mission to redefine foldable phones. It’s set to steal the spotlight at MWC 2026, showing off what’s next for mobile tech.
