Samsung’s Galaxy Z Fold 3 and Flip 3 are the best foldable smartphones you can buy right now. They’re not perfect, but they’re better than anything of Samsung’s previous attempts when it comes to durability. They’re also more affordable than ever, and Samsung included the new Fold and Flip smartphones in several Black Friday sales that further discounted the entry price.
But several of Samsung’s big rivals from China plan to launch foldable handsets soon. And they’re researching even crazier concepts for foldable devices. Like Vivo’s hinge-less, tri-fold foldable smartphone in these renders that can project a full laptop keyboard in front of it.
