Oppo tweeted on 14th December showcasing their new triple-hinge smartphone collaboration with Japanese design studio, nendo.
Most probably the smartphone name will be OPPO X Nendo. You can fold this phone three times.
Sliding the first fold opens a 40-millimeter screen which allows you to do functions that don’t need a full screen. For example applications like call history, notifications, and more.
Sliding the smartphone a second time opens an 80-millimeter screen that allows you to “take pictures or even adapting to particular games using the slide control”.
