If you've ever used one of Samsung's flagship large phones or phablets, then you're likely well-aware of the Korean firm's so-called one-handed mode. One-handed mode is exactly what it sounds like—it makes it so that you can use a device that would normally take two hands to operate, with a single hand.
Of course, Samsung isn't the only company to offer such a feature. Apple revealed Reachability, a tool that allows users to pull down the iPhone 6 and 6 Plus' interface, for easy one-handed usage. Although both features are designed to make it possible to operate a larger device with one hand, the methodologies behind the features couldn't be any different.
