TECNO is pushing the boundaries of foldable innovation with the unveiling of its latest concept phone the PHANTOM Ultimate G Fold. Touted as the world’s thinnest tri-fold smartphone, this futuristic device takes aim at heavyweights like Samsung, OPPO, and HONOR with groundbreaking design and portability.
Ultra-Thin, Game-Changing Design
TECNO’s PHANTOM Ultimate G Fold Concept is a marvel in mobile engineering. When folded, the device measures just 11.49mm thick, making it thinner than the Galaxy Z Fold 6, and when fully unfolded, it’s a mere 3.49mm significantly slimmer than rivals like the OPPO Find N5, HONOR Magic V5, and Galaxy Z Fold 7, which range between 4.1mm and 4.2mm.
This ultra-slim profile doesn’t come at the cost of strength. The phone features an inward-folding design with two displays, a configuration TECNO claims provides better screen protection and durability compared to outward-folding alternatives like the Huawei Mate XT.
Advanced Dual-Hinge System
At the heart of this innovation lies TECNO’s custom dual-hinge mechanism, combining:
• A small waterdrop hinge for smooth, gapless folds
• A larger self-locking hinge for structural integrity and seamless closure
This system allows the device to fold like a traditional book while maintaining a compact and secure profile when closed. The result? A foldable phone that feels less like a prototype and more like the future of flagship smartphones.
Massive 9.94-inch Display with Minimal Creasing
When unfolded, the PHANTOM Ultimate G Fold Concept transforms into a 9.94-inch tablet-like device with “minimal creasing,” according to TECNO. This makes it perfect for multitasking, streaming, content creation, or productivity on the go without the bulk of carrying a tablet.
Whether you're gaming, watching 4K videos, or editing documents, the expansive screen aims to offer a seamless experience, blurring the line between smartphone and tablet.
Over 5,000mAh Battery & Powerful Hardware
While TECNO hasn't revealed the full specifications yet, a few details have been confirmed:
• High-performance chipset (likely flagship-grade)
• Versatile triple-camera system
• Battery capacity over 5,000mAh for all-day usage
These features suggest that the PHANTOM Ultimate G Fold Concept isn’t just about style it’s designed to perform at flagship levels too.
From Concept to Reality: What’s Next?
This isn’t TECNO’s first time exploring the world of advanced foldables. The company previously showcased the PHANTOM Ultimate 2 tri-fold concept at MWC 2024, which earned praise for its ambitious design.
Now, the PHANTOM Ultimate G Fold is expected to be showcased at IFA 2025 in Berlin this September. While it’s still a concept device, its refined engineering suggests TECNO may be inching closer to a commercial release.
