Many of us with more than a passing knowledge of phones know Samsung is all but certain to reveal more about its foldable handset next week. Until then, it knows it has something significant to show off, and it's trying to build hype for its Unpacked event. It's like a relative who got you a cool gift for your birthday, and can't stop excitedly babbling without actually telling you what it is (even if it is a "gift" that could cost you over $1,700).
