Chinese tech firm Huawei unveils first tri-folding phone

Chinese tech giant Huawei unveiled on Tuesday its tri-fold smartphone outside China

The Mate XT Ultimate Design is the first phone in the world to feature a dual-hinge system, where the flexible OLED display can expand from a compact 6.4 inches to a tablet-like 10.2 inches when fully unfolded.

It operates on Huawei's proprietary software instead of Google services.

The Mate XT's starting price point is approximately 3,660 U.S. dollars, and is currently listed for sale in several countries, including Malaysia and Saudi Arabia.

Pre-orders have reportedly surpassed 6.5 million units.
