Samsung delivers on the promise of a foldable phone at its 2018 Developer Conference-- specifically by showing off an "Infinity Flex" technology consisting of a main 7.3-inch and a 4-inch display on the back.
“The foldable display lays the foundation for a new kind of mobile experience," Samsung CEO DJ Koh says. "We are excited to work with developers on this new platform to create new value for our customers. We cannot wait to see where the technology and collaboration takes us.”
Seen in admittedly chunky prototype form, the Infinity Flex device seamlessly shifts from folded to unfolded modes. To do so it runs on One UI, a take on Android Samsung says "delivers a new kind of mobile experience." According to the company, One UI allows apps to transition from the smaller to larger display as the device unfolds, as well as simultaneously run up to 3 apps on the larger display.
