Samsung has been developing foldable display technologies for a long time, and it seems that a foldable phone/tablet is always just around the corner. In September 2017 Samsung's Mobile Business group President says that it hopes to have a foldable phone in the market in 2018, and according to new reports from Korea Samsung is now expected to start production in November 2018. The phone will have a 7.3-inch display that folds inside.
The Korea Herald reports that the foldable phone will be introduced in December 2018 or early next year. Samsung Electronics already finished the phone's design and specification, and Samsung Display is expected to complete the display development by March 2018. The actual panel production will commence in September 2018.
Finally, the report suggested that Samsung is demonstrating its foldable display in private meeting during CES this week.
