With its glossy, mirror-like finish and dual screens, the Galaxy Fold may look delicate. But it certainly didn't feel fragile when you're using it, at least during my experience with the device; opening and closing the Galaxy Fold doesn't feel much different than snapping shut a flip phone.
Samsung says the phone's dual-axis hinge is built to withstand 200,000 folds and unfolds, which means it's designed to last for at least five years if you open and close it 100 times per day. Of course, we won't have a better sense of the phone's durability until we've used it for a longer period of time.
