"We are still working on it." he said. It's hard to say how well the hinges will hold up over time - or, indeed, the flexible OLED - without putting the device through its paces.
Samsung's mmWave radio frequency integrated circuits (RFICs) and digital/analog front end (DAFE) ASICs supports 28GHz and 39GHz bands, which can reduce 5G base station size, weight, and power consumption by 25 percent. However, when unfolded it creates a combined 8-inch display.
Meanwhile Yu highlighted that the Mate X's two batteries give it 4,500 milliamps per hour (mAh) which is "well above that of its competitors", and these batteries can be recharged in just over half an hour.
When folded, the thinner side of the Mate X tucks in nicely against the spine.
Huawei Mate X comes in a single blue colour that has 8GB of RAM and 512GB of storage.
Yu also noted that the Huawei Mate X is 5G-ready, sporting the company's Kirin 980 CPU alongside its Balong 5000 5G modem, all wrapped up in a 7nm chipset. This first set of foldy phone launches seems to be as much about bragging rights, technological chest-beating and headline chasing as anything, but that doesn't mean they're not interesting.
Because of the way it's designed, this camera phone is one of the first to use the same camera for selfies and normal camera shots.
Smartphones with foldable displays allow a device to go from being the size of a phone to the size of a tablet. Folded, meanwhile, the phone is 11mm thick.

North Korea has warned that it is facing a food shortfall of some 1.4 million tonnes this year, forcing the regime to nearly halve rations.
To make the phone as thin as possible, Huawei had to include a variety of clever workarounds.
The DragonHinge lets phones fold completely flat. Samsung's One UI enables you to activate a black bar at the top of the display, as you would on a number of phones that come with a display notch.
"That said, no matter how innovative and technology-advanced the new device is, it will take a lot more time for a critical mass of consumers to experience the benefits of foldable phones and 5G technology".
The company also said the device will contain a large 4500mAh battery, as well as "SuperCharge" - enabling it to charge from zero to 85% in only 30 minutes.
More specs will follow, as at our briefing there were no questions taken despite the lack of further details.
The program that will be part of the marketing advertisement for the new phones will highlight that a person who shares his or her power with others will one day be able to receive the same favor form a person who is into the promotion of power sharing. We're sure there are more practical uses, but really, it's just there to bleed into the front screen as the device's large display when it's opened.
Huawei has also unveiled three new MateBook laptops with touchscreen displays.
