I don't really see the appeal of a folding phone. Moving parts break. The screen will scratch more easily, than just having a glass, defeating the purpose. The industrial design of a phone hasn't changed much since the original iPhone. "Black rectangle with a touch screen". Apple cant keep selling you a new phone every year, so they have new products like watches and AirPods. Soon perhaps glasses. But a folding screen? I guess its a neat bit of engineering, but it seems like a solution looking for a problem.
