New Delhi, Delhi, India | 17th July 2025: TECNO Mobile has officially introduced its latest innovation in foldable smartphones—the PHANTOM Ultimate G Fold Concept. Featuring a dual-screen, inward-folding tri-fold design, the device unfolds into an expansive 9.94-inch display, setting new benchmarks in foldable phone durability, slimness, and performance.

Industry-Leading Thinness and Design

When folded, the PHANTOM Ultimate G Fold measures just 11.49mm, and when fully unfolded, it boasts an ultra-slim 3.49mm profile—making it the world’s thinnest tri-fold smartphone to date. This impressive feat is achieved through cutting-edge materials and engineering, including 2000 MPa ultra-high-strength steel hinges and a 0.3mm Titan Fiber back cover.

Revolutionary G-Style Tri-Fold Architecture

The smartphone introduces a unique G-Style tri-fold structure that folds inward twice, protecting the flexible display from scratches, dust, and impact. Unlike traditional foldables that expose part of the screen, TECNO’s design keeps the main display completely shielded when not in use. A secondary cover screen offers a standard smartphone experience for daily tasks.

Central to this innovation is a custom dual-hinge system:

  • A small waterdrop hinge enables a gapless fold on one side.
  • A larger main hinge folds the final segment over the top.
  • A self-locking mechanism ensures a secure and seamless fold every time.

This dual-hinge architecture also supports multi-angle hovering, transforming the device into a mini-workstation—ideal for productivity, content creation, or hands-free use.

Immersive 9.94-Inch Display for Multitasking

When fully unfolded, the PHANTOM Ultimate G Fold offers a nearly crease-free 9.94-inch tablet-like display, designed for immersive multitasking, gaming, and media consumption. The screen provides a smooth, seamless experience, ideal for professionals and tech enthusiasts seeking next-gen productivity on the go.

Flagship Features in an Ultra-Slim Form

Despite its complex foldable design, the PHANTOM Ultimate G Fold Concept delivers flagship-level performance:

  • High-performance processor
  • Versatile triple-camera system
  • Over 5000mAh battery capacity for all-day usage

TECNO’s Ongoing Innovation in Foldable Technology

The PHANTOM Ultimate G Fold Concept continues TECNO’s tradition of pushing boundaries in smartphone design. Following the success of the PHANTOM ULTIMATE 2, TECNO’s ultra-thin triple-fold concept showcased at MWC 2025, the brand once again captures global attention with its bold design and engineering excellence.

This latest concept highlights TECNO’s commitment to bringing advanced foldable smartphones to a global audience that values innovation, performance, and elegant design. The company has confirmed plans to showcase the PHANTOM Ultimate G Fold at MWC 2026, further establishing itself as a leader in the future of foldable mobile technology.
