A Silicon Valley-based company has released a futuristic smartphone that folds.
The FlexPai is billed by its developer Royole as the world's first folding smartphone and has an extremely flexible screen that can be bent from the middle.
With a thickness of just 7.6 mm, the dueling camera handset was introduced in China this week and can now be pre-ordered online.

When the screen of the phone is 7.8 inches (19.8 cm) completely bent back from both sides, the user has three instead of two display screens.
In addition to the front and back display, the backbone becomes a third, albeit small, screen on which incoming calls, messages or emails are displayed when they are received.
Depending on the specifications, the price of the phone in China ranges from 8,999 yuan (US $ 1,000) to 12,999 yuan (US $ 1,452) for a consumer model or developer model.
However, only the developer model outside of China was released for £ 1,209 for a 128G edition and £ 1,349 for a 256G edition.
The phone weighs only 320 g and has two cameras above.

The state-of-the-art mobile phone was unveiled on Wednesday in Beijing by Bill Liu, the 35-year-old founder and CEO of Royole.
Liu is a Chinese entrepreneur with a PhD in electrical engineering from Stanford University. He founded his company six years ago with offices in the US and China.
Liu has given the screen a poetic name, Cicada's Wings, to highlight its light weight, flexibility and durability.
Liu said the screen was exclusively developed by his team and includes more than 20 million flexible, high-precision devices, flexible integrated circuits, and nearly 100 micro- and nanostructured thin-film materials.
Liu said his team has screened for around three years and has more than 2,000 intellectual property rights.
Experts previously said flexible screens are more durable and durable than glass-front touchscreen displays used in most current smartphones.
Foldable strainers can not be damaged if dropped, and are lighter and cheaper to manufacture.

The introduction of FlexPai has surprised many industry observers.
It was widely speculated that Samsung or Huawei would be the first company to launch a foldable phone.
DJ Koh, Samsung's Samsung CEO, previously told CNBC that such a device is in the works, adding that the company was trying to distinguish the experience from a tablet as it unfolded.
The Korean tech giant is expected to hold a developer conference in San Francisco next Wednesday that could give the public a preview of the technology.
Huawei CEO Richard Yu said in September that the Chinese company is working on the development of a foldable display phone, adding that it will be launched next year. The new phone would also support super fast 5G network speeds.
FlexPai was also released when Chinese smartphone users shifted their focus from low-cost to high-quality, eye-catching designs.
According to a new report from the Internet Data Center, around 105 million smartphones were sold in China in the second quarter of this year.
Although down 5.9 percent from the same period a year ago, consumers expressed a desire to buy cell phones with a newer technology they had not seen before.
