The Samsung Galaxy Flex, as many have taken to call it, is confirmed to make at least a small appearance during the event. An official video teaser (above) effectively states as much.
While the Samsung Galaxy S10, Galaxy S10+ and Galaxy S10e are expected to be the main focus during the livestream press conference, as evidenced by the "10" at the end of the clip and on invites, the foldable phone will also make its debut.
The words "The Future Unfolds" and perpetual folded screen imagery leave little else to the imagination.
Samsung did demonstrate a working prototype during its developers conference at the tail end of last year, but this is likely to be the first showing of the full consumer model.
It is not known yet whether it will be just a tease or a proper declaration. However, with Samsung Unpacked occurring on 20 February, a week before Mobile World Congress is due to start, the company can get a heads-up on any competitive devices that could appear during the show in Barcelona.
