There is not much to see in the video, but the words in the video seem to be about a foldable surface, an indication of Samsung's first smartphone with this foldable design.
Samsung unveiled Infinity Flex display technology in November and demonstrated this on a device with a flexible 7.3-inch display that folds in half on the right, from a tablet size to a smartphone Size collapsed.
At the time, Samsung said it needed to invent new materials and redesign the display to develop its Infinity Flex technology.
Samsung is working with Google to develop a new software platform for the device that will support two user interfaces – one when the device is open and one when the device is closed.
Samsung's foldable smartphone will debut on the occasion of its upcoming event on February 20, where the new Galaxy S10 smartphone program will hit the market.
Galaxy S10 devices do not have foldable displays, but there are three options at different price points and with different display sizes. Samsung's Galaxy S10 is designed to provide small "punch" camera cutouts to maximize the available screen area.
