KingRoot is an application that allows you to root your Android device in seconds, as long as you have an operating system between Android 4.2.2 and Android 5.1. This means that this app allows you to do the same as the classic Towelroot, but you can use it even if you own Lollipop.
The procedure to root your device is as easy as Towelroot. Even though the app is entirely in Chinese, the only thing you need to do is press the blue button and wait. After a few seconds, the app finishes working and you will have your device rooted.
It is important to know that KingRoot does not work with all types of devices. On Moto G, for example, it usually has some issues. With Nexus, though, it usually works just fine.
KingRoot is a great way to root your Android device. That said, rooting a device is always a delicate process, so do it with care and be aware of the risks involved.
