The device is actually made up of two distinct smartphones, each with their own processor and housing. Both also are equipped with three magnets that allow the two phones to be attached in several different orientations. One method uses cylinder shaped magnets found in both phones to attach the two devices side-by-side. This would create a device with a larger screen, almost like a foldable phone (except for the frame that appears in between the screens).
When the two screens are attached together, they can act like one giant screen, or each display can act separately. For example, you might be streaming a Netflix movie on both screens, or watch the movie on one screen while texting on the second display. There are also configurations for taking selfies, and for typing emails and texts with a virtual QWERTY keyboard.
