Foldable phones have stolen the MWC show in February but those might not be the only kind of foldable devices manufacturers have in mind. After all, when you are not limited by screen space, anything can be folded. The problem, however, is either in the screen, the hinge, or both. Lenovo has patent yet another one of its ideas though, this time, its "connecting assembly", a.k.a. hinge, is something Microsoft will be too familiar with.
