Reliable tipster Ice Universe shared on X that Samsung’s mobile division has begun developing a phone whose display can roll outward and upward, shifting its proportions from a 16:9 ratio when retracted to a 21:9 ratio when fully extended. The panel would slide out from the body along side rails rather than fold open on a hinge, and the same post indicates the screen can stop at intermediate lengths instead of always traveling the full distance. Concept images accompanying the claim show a relatively short device in its closed state that becomes noticeably taller once the upper section has moved outward.
