How does it fold?
The Samsung Galaxy Z Fold 2 can be used in both its folded and open forms. But what makes this design even more satisfying is a built-in mechanism that allows the phone to stay open at any angle in between. Instead of allowing the device to snap shut, Samsung developed two hinges that hold the two panels together. These hinges are strong enough to support the weight of the large phone in any position. But how do you engineer a delicate screen to fold and become flexible without it simply shattering? With this model, thin aluminium sticks are aligned along the part of the screen that bends. This strong material adds support to the display, while the gaps allow for movement. Using one solid piece of metal wouldn’t work, as it would become too stiff to bend.
