Huawei follows rival Samsung’s footsteps, releases foldable phone

Huawei has revealed its first smartphone to feature a foldable screen, less than a week after its rival Samsung did the same.

The rival handset-tablet hybrids have contrasting designs, reports BBC.

Huawei's Mate X places its fold-out screen on the outside of the device, so that it covers the front and rear of the phone when closed.

In both modes, the display is larger than Samsung's. Huawei's device is also flatter and thinner when shut.

However, unlike Samsung's Galaxy Fold it does not have a second display on its reverse side.

One analyst attending the launch event in Barcelona also remarked that a crease in the screen appeared to be visible.

The Chinese company allowed attendees at the event to get a close look at the handset following its unveiling. Its South Korean competitor has yet to let outsiders to do so with the Galaxy Fold.

"Security concerns about Huawei's 5G kit are a shadow hanging over the whole of this year's Mobile World Congress," commented the BBC's technology correspondent Rory Cellan-Jones.

"But the firm was determined in a confident, even arrogant press conference to convey that it's now the leading innovator in smartphones."

For comparison's sake, Huawei said:

• the Mate X's screen is 8in (20.3cm) when unfolded
• when closed, the Mate X's larger screen is 6.8in and the smaller one 6.6in - which makes both bigger than that of the iPhone XS Max
• when shut, the Mate X is 11mm (0.43in) thick
• the Samsung Galaxy Fold's main screen is 7.3in (18.5cm) when unfolded
• the Fold's other display is 4.6in
• the Fold measures 17mm (0.67in) thick at its widest point when closed
• Unlike the Fold, the Mate X does not place any of its cameras on the same side as its screen when unfolded.

Instead they are placed on the flipside of the device on a strip that also features a fingerprint sensor. This runs down the side of the smaller of the two folded displays when closed and doubles up as a side-grip when open.

This potentially places the Mate X at a disadvantage to the Fold, since it becomes impossible to use its unfolded screen to take selfies. However, it is not yet clear whether this will be a serious consideration in practice.

However, the Mate X's advantage is that it does not have a "notch" cut into its screen as a consequence.
