How to get a one-handed mode on any rooted Android device

With smartphones transforming into more and more potent computing devices, it makes sense that we want larger screens than before. After all, a 3-inch display will hardly allow you to be very productive -- items are too small, and your fingers are just too big. This has caused some serious growth in device's dimensions, with 5-inches now being something of an average across the industry. And while those larger screens definitely come in handy, they can also be quite frustrating to handle with one hand, whenever you just need to perform an operation quickly -- like calling your mom. God forbid you need to reach for the status bar to pull down the notification panel.
