Oppo X 2021 is the first working rollable smartphone that a mainstream company has ever launched. This rollable phone has a rollable mechanized display that extends with just a touch or a swipe. It looks like any other smartphone with a 6.7-inch curved-edge display at first glance. But a simple swipe on the side will expand the display to 7.4-inches for that tablet experience. Samsung and LG will also launch a rollable smartphone next year.
