Kingo ROOT works on dozens of different device models that use any version of Android between 1.5 and 5.0. And all of them use the same process for rooting the device: hit the ROOT button. Of course, if your device is already rooted, the app will tell you so. You can also unroot a device the same way that you root it, all in a matter of seconds.
During the app's installation, a pop-up window may appear saying that installing Kingo ROOT is dangerous. This is because rooting a device always implies certain risks. In any case, you just have to hit 'Install Anyway (unsafe)' to proceed.
Kingo ROOT is a good app for rooting your Android that will allow you to root your device in seconds. The best part: a simple interface and a process that takes less than 20 seconds.
