The full specs on Samsung’s latest foldable phone, the Galaxy Z Fold 2, still aren’t out. What we do know: the second-gen phone features a larger edge-to-edge dual screen design with 7.6-inch displays. It is also considerably thinner, packs a 4500 mAh battery, and an improved hinge designed to withstand opening/closing 200K times. Pre-order begins Sept. 1.
