Oppo’s foldable smartphone is another futuristic wraparound display device

Mobile World Congress is happening this week, and so far it has definitely been the foldable smartphone show. Samsung and Huawei have so far wowed the world with their folding smartphone demos, offering a tantalizing future in which a smartphone can open up into a tablet. Next up in the foldable smartphone wars is Oppo, with the company's vice president, Brian Shen, showing off this unnamed prototype foldable on Weibo, a Chinese social media site.
Oppo's foldable looks a lot like the Huawei Mate X, with a wraparound exterior display and a vertical bar for cameras, buttons, and ports. It might be a bit of a shock just how similar both devices look, but they are no closer than any two of the thousands of anonymous slab phones that are out there. Both devices look impressive, but Huawei has pushed its display further out to the edges of the device, resulting in thinner bezels and a more modern look. The two companies have also taken a different approach to the critical hinge design on their respective foldables. Huawei is using a 'stretchable' hinge that gets longer when it opens, which should help make the screen tighter and flatter when opened. Meanwhile, Oppo's hinge looks like a bike chain topped with a double pivot hinge system. We don't actually know how Oppo's hinge works or if it closes totally flat, but it certainly looks complicated.
Every foldable smartphone vendor is at a different stage of development and/or unveiling. Samsung demoed the Galaxy Fold on stage, but the company isn't letting anyone touch the device at Mobile World Congress. There are some early prototypes on display in glass boxes at MWC, but Android Police reports that some of these devices feature dimples and creases in the display, so there are still some bugs to work out. Samsung is the only company with a firm release date, though: April 26th.
