The first foldable-screen smartphone will come with three primary cameras at once.
The ambitious Chinese company is also planning to compete in this category of smartphones, having been preceded by a Samsung Galaxy device and Huawei Mate X.
Significantly, the Samsung Galaxy Fold suffered a lot of problems before its release, after the company pulled it out of the market to remove these shortcomings, most notably the rapidly damaging display.
Samsung's experience led the South Korean company to work on its treatment, and then officially delayed launching the phone, where it should be released in Q4 2019.
China's Huawei intends to unveil its "Huawei Mate X" folding phone in September after saying it at the World Smartphone Conference.
