KingRoot is an app that lets you root your Android device in a matter of seconds, as long as the operating system is between Android 4.2.2 and Android 5.1. That means that you can achieve the same result as if you were using the classic Towelroot. Except that you can use it even if you have Lollipop.
The rooting procedure is as simple as it is with Towelroot. Although the app is entirely in Chinese, you simply have to tap on the blue button and wait. After a couple of seconds, the app completes the process and your device is rooted.
It's important to know that KingRoot doesn't work with all devices. With Moto G, for instance, you can run into some trouble. With Nexus, though, it usually works perfectly.
KingRoot is an excellent way to root your Android. That said, rooting a device is always a delicate process, so tread lightly and be aware of the risks involved.
