Samsung previews phone with a screen that folds like a book

[SAN FRANCISCO] Samsung Electronics showed off a new phone with a foldable screen in a bid to shake up a smartphone business awash with black, shiny rectangles that look increasingly similar.

At its conference on Wednesday for software developers in San Francisco, the company previewed what it called an Infinity Flex Display, and announced new software for controlling the large phone. Developers will be able to create apps for the gadget, which like other Samsung phones, will be based on the Android operating system.

The South Korean technology giant didn't say when the device will go on sale, how much it will cost, or what the phone will be called. During the presentation, Samsung also disguised the rest of the phone's design by covering everything beyond the screen with extra casing - similar to how prototype cars are camouflaged during street testing.

The basics, however, are clear. The device looks like a standard smartphone when closed. It opens like a book to reveal another 7.3-inch display, which would be one of the largest phone screens ever released. It will be big enough to run three apps side by side, up from two on the Note 9, Samsung's most-recent large smartphone.

The company said the display can be folded hundreds of thousands of times. Samsung said it's also exploring screens that roll and stretch, but didn't preview devices with those technologies.

Samsung plans to release a simulator to help developers write and test apps for the foldable screen and will host sessions with developers to teach them how to write software for the device. The company is working with Google and its Android division on the underlying software to power the foldable device. Glen Murphy, director of design for Android at Google, spoke at the conference.

In October, Bloomberg News reported that the folding phone would go on sale during the second quarter of 2019 at the earliest. Samsung confirmed on Wednesday that mass production of the screens would begin in coming months.

Samsung isn't the first to try foldable phones, but the company's display know-how, reach and marketing power could take the form mainstream. Last year, ZTE Corp announced a foldable phone that flopped with reviewers. Earlier this week, consumer electronics startup Royole announced a similar device in China.

Samsung also showed off a new software interface called One UI, which includes simplified controls, new icons, and more rounded corners. The new look is optimised for controlling devices with one thumb, a necessity as screens become larger.

The interface will come out as an early test version in the US, Germany, and Korea this month, Samsung said. The software will officially launch on the Galaxy S9 and Note 9 in January.
