Already mentioned last spring, Samsung's three-section smartphone project resurfaced through a recently registered patent, unearthed by Let's Go Digital. The document describes in detail the guts of this three-section smartphone which when unfolded takes the form of a large tablet.
Z-fold and HDMI connector
The device folds thanks to two hinges with opposite folds, giving the whole a Z shape when fully folded / unfolded. The patent gives more details, like the camera hidden under the screen, S Pen compatibility, and even an HDMI connector. As a reminder, patents do not provide definitive information on the final functionalities of a product, but allow us to give big clues about its design and its potential functioning.
