Samsung has shown its first folding smartphone at the SDC Developer Conference in San Francisco. When folded, the futuristic cell phone finger is thick – revealing an impressive large screen with a 7.3 inch (18.5 cm) diagonal and a resolution of 2152 × 1536 pixels (420 dpi). The screen should be "hundreds of thousands" of folding operations.
Mass production of the folding screen begins, according to Samsung, already "in the coming months". Details on devices using the so-called "Infinity Flex" screen are not yet available.
A user interface provides folding support
The device demonstrated by Samsung has a small display (840 × 1960 pixels in 21: 9 aspect ratio), which is active in closed mode. If you open the smartphone, the app used on the small screen will appear without delay on the large drop screen (see video below). Samsung's new user interface "One UI" provides support for the Falt screen. Another feature is simultaneous display of three apps on display, Samsung calls "Multi Active Window".
A developer's mobile emulator is scheduled to be released later this year on Samsung's developer website.
Google has also announced that it will support Android Falt smartphones from the next version of its mobile operating system. Google calls the new device genus "Foldables".
Apparently thinner than Royole FlexPai
Samsung is not the only manufacturer with Falt phones – and not the first: The Chinese company Royole has Flexold already a foldable market, opening its screen is 7.8 inches long. FlexPai looks thicker than the Samsung device; However, we could see this only for a few seconds under low light on the SDC scene. Samsung has not yet released product images, there are only schedules.
Samsung has used flexible screens since 2011, and since then, Koreans have demonstrated technical studies on flexible OLED screens. However, concrete products have not appeared so far.
update: Information about the resolution of both screens added.
