Huawei launched the world’s first tri-foldable phone – the Huawei Mate XT, featuring a folded thickness of 12.8mm and 3.6mm when unfolded. While Huawei is expected to unveil the Mate XT 2 in China this September, Samsung is also reportedly developing its first tri-foldable, possibly called the Galaxy Z TriFold. In a surprise move, Tecno has announced its own tri-foldable concept called the Tecno Phantom Ultimate G Fold. The device follows up on the Phantom Ultimate 2, a concept phone first showcased at IFA 2024. Read on for the full details of Tecno’s ambitious foldable innovation.
Tecno Phantom Ultimate G Fold: Everything you need to know


The Phantom Ultimate G Fold introduces a unique inward-folding tri-fold design that hides its large display when not in use. Unlike outward-folding counterparts, this layout protects the screen from scratches and impact damage. It features a 9.94-inch display that folds inward in two sections, supported by a dual-hinge setup comprising of a waterdrop hinge for the right side and a larger hinge that folds over the top.
This enables gapless folding and a secure, compact closure. A cover display supports regular smartphone use without needing to unfold the entire device. The hinge system also allows multi-angle hovering, turning the phone into a compact workstation.


Tecno claims the Phantom Ultimate G Fold is the thinnest tri-fold smartphone to date, measuring 11.49mm when folded and just 3.49mm when unfolded. These dimensions outperform existing tri-folds, thanks to innovations in materials and engineering. The hinge uses 2000MPa ultra-high-strength steel, while the back panel is crafted from 0.3mm titan fibre. Despite its compact size, the concept includes a high-end chipset, a triple-camera setup, and a battery exceeding 5,000mAh.
A concept phone is an experimental prototype designed to highlight futuristic technologies or design innovations that are not yet found in regular smartphones. These devices are primarily developed to showcase what’s possible down the line, and they are usually not meant for commercial sale, meaning most of them won’t be available for public purchase. However, Tecno has confirmed that the Phantom Ultimate G Fold will be showcased at the MWC 2026.
