I saw that some guys want to root their phones. For those with LG ones you need to follow these steps to root your phone without a pc or any extra hardware.

1. Download KingRoot app and install it on your phone. You need to allow installation from unknown sources (as this is an APK)
2. Open the app and start the rooting process. Everything you need to do is press the One Click Root button and wait for the process to be ready
3. After the rotting process is complete, you will see the “Root succeded” message on your phone’s screen
4. Additionally, you can get the Root Checker app and see if the rooting of your LG was done properly.

There are several benefits to rooting a phone. BUT! Always pay attention and DO NOT root it unless you need it this way. The risk, when rooting, is that you can make your phone unusable.
