As we said before, most rooting software will also download SuperUser on your phone, so there will be no need for you to do it on your own. In case it didn´t happen, or you want to install a newer version, you can do it. The easiest way is to go to the Google Play Store and download it. There are two versions available to you. First is the basic version that secures your phone from malicious and unauthorized access to the important parts of your phone. This version is free, but you may also get SuperUser Elite for a price of about 3 USD.
Beside features from the basic app, SuperUser Elite has several upgraded features, such as NFC support, apps settings backup and restore, PIN protection of the app, advance log management, notification settings for different apps and ghost mode.
How to use SuperUser
Before you continue, make sure that you root G3, as this is extremely important!
As you can see, using SuperUser is easy and simple. If you want to learn more about it and if you want to use all the features it offers, the best way is to take some time and explore it a little bit. For many reasons, this is an app you simply must have on your LG G3 after rooting, and if your rooting software did not install it automatically, make sure that installing SuperUser on your rooted LG G3 be the very first thing you will do once you rooted it.
