The OPPO x nendo Conceptual Slide-Phone is a versatile and practical device that can fold into three different screen sizes. This concept developed from the idea of owning a phone with a large screen that can become difficult to hold. However, the Slide-Phone unfolds vertically for convenience and a unique design. The first fold reveals the clock and your notifications. One further segment displays the selfie mode. Finally, the third unfolding presents a widescreen display that’s suitable for scrolling the internet, playing games, watching videos, and more. All the while, the side buttons remain usable and visible. In fact, these buttons have different purposes depending on the mode you’re in. And, if that’s not enough, the OPPO x nendo Conceptual Slide-Phone accommodates a built-in stylus, too.
