Huawei CEO Richard Yu had previously hinted at a foldable phone during an investor meeting in January and he was on stage in Barcelona to showcase the Mate X and its foldable screen at a conference session.
It offers "an expanded view in one hand," said Yu. "Other foldable phones are like two phones together, this is just one phone," said Yu.
Huawei appears to be positioning the Mate X foldable smartphone as a productivity device, offering users the ability to browse multiple tabs or files at once when performing workplace tasks. "This looks like you're using a tablet, but it's much lighter than a tablet," said Yu.
The Huawei Mate X is the second foldable smartphone to be unveiled in the space of just a few days — Samsung pipped Huawei to the post to be first to reveal a foldable device, the Galaxy Fold. Like the Galaxy Fold, there's a price tag issue. The Mate X will run $2,600 for three cameras and three screens. CNET's Jessica Dolcourt said:
Huawei's vision for the Mate X is of a phone you mostly use in its "closed" position, but open up when you want to be entertained or more productive.
There's a key difference between the two phones, however: the Galaxy Fold folds in on itself like a book, with the screen inside the device when it is closed. The foldable screen of the Huawei Mate X is folded around the outside of the device, with the help of a patented hinge with over 100 components, the company said.
Yu was also keen to stress that the Mate X has a larger screen than the Galaxy Fold — 8-inches across. Compared with the Samsung device, Huawei said the Mate X is also thinner when folded than it's big rival: 11mm compared with 17mm.
The 5G on the device also appears to be a move to place the phone as an enterprise tool, offering users high speed downloads, as well as fast charging speeds. The connection is also said to provide encryption for more privacy and security when using the Mate X. The company said a 30-minute charge can add 85 percent battery power to the phone.
A cover is also offered for the device in order to protect it from damage. The cover bends around the fold.
The Mate X foldable phone is set for release in the "middle" of 2019 and will cost €2299, the company said.
The Mate X also fits in with Huawei's plans around 5G, with the new foldable phone touted as an exclusively 5G device with the company boasting it can take advantage of what they describe as the most powerful 5G on the market.
Huawei featured 5G heavily in the presentation, with a variety of Internet of Things and connected-home devices displayed, along with a 5G mobile hotspot.
Huawei also unveiled the Huawei Mate XP Pro laptop, offering users what Yu described as a "borderless experience" with a 3:2 aspect ratio. "It's better for productivity over 16:9, better for performing, better for reading documentation," said Yu.
Other new hardware includes the Matebook 14, a 14-inch touchscreen laptop that Huawei said can be used for 14 hours without charging for office work. It appears to be designed for high-power enterprise users who need to have long batter life.
The new hardware has been launched alongside Huawei Share OneHop, a wireless means of sharing files fast between compatible devices. Tapping a phone against a laptop transfers the file immediately and also works with clipboard items, pictures and videos.
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.
