Samsung gave the first glimpse of its upcoming foldable phone during the fifth annual developer’s conference that took place at San Francisco. Justin Denison, Samsung senior vice president of mobile marketing, showed off the phone, which is a tablet when it's fully opened and then a phone when it's closed. It uses a new display technology called Infinity Flex Display that lets you open and close the device over and over without any degradation.

Samsung isn’t the only phone maker working on foldable devices; Huawei also plans to release a foldable phone next year. Lenovo and Xioami have also started teased their own prototypes, and, LG is also working on flexible OLED displays and TVs that roll into a box. The device includes two screens with one on the outside cover working as the traditional phone, while users can open up the device to reveal a larger display. Meanwhile, the second features one continuous screen on the exterior. One of the reasons why Samsung teased this device at its developer’s conference was to give software-makers a chance to think about how to make the most of the new possibilities a foldable screen might bring. Let’s eagerly wait for the next update!
