Motorola has been working on a foldable smartphone for a while. Moto wants to avoid faster wear and tear of OLED panel with a clamshell design. Motorola might even bring a dual-hinged folding smartphone. Motorola is working on a foldable device that might make it to the commercial market very soon. What Motorola wants to do is to preserve the display with protective design. Motorola also has more ambitious plans.
What Dery meant is that the conventional design that Huawei and some other manufacturers adopted for their foldable smartphone might not be a reliable implementation for the future. Foldable OLED panels are made of plastic that is more prone to scratches from fingernails than glass. The more scratches a flexible display gathers, the more its touch-effectiveness goes away.
What Motorola wants to do is to preserve the display with protective design. The company is working on a clamshell design where the display will stay protected when folded - similar to a Samsung Galaxy Fold. This falls in line with the leaked renders of the RAZR concept in which one could fold a phone into a much more pocketable size when not using it. However, Motorola also has more ambitious plans.
