This means that this app lets you do the same thing as the classic touheler, but you can use it with Lollipop.
Your device's root system is as easy as Towelroot. Even if the app is completely in China, then whatever you want to do is hit the blue button and wait. After a few seconds, the app will finish the job and you will have your root device.
It is important to know that KingRoot does not work with all types of devices. Moto G, for example, it usually has some trouble. With Nexus, though, it usually works perfectly.
KingRoot is a great way to root your Android device. That said, rooting a device is always a delicate process, so be careful with it and be aware of the risk involved.
