Resources you’ll need after you root
No other mobile operating system parallels the diversity of Android OS. For this reason, there’s no universal way to root your device. If the above two options fail, don’t fret. There is likely a guide on how to root your specific device available somewhere online. Generally you can find a guide to your device at places like XDA developers’ forum or the Phandroid Forums.
Once you have found the right guide for your phone or tablet, it’s simply a case of working through the listed steps methodically. It can be a complicated procedure and it can take a while. Here’s an example guide for rooting the Samsung Galaxy S4. It can appear intimidating at first glance, but provided you follow it step-by-step, it should be a pain-free process. You can post questions in the XDA Developers forum if you run into trouble.
Download Root Checker
You’ll need to download another app to make sure your device has been successfully rooted. There are several apps available on the Google Play store that, when downloaded, will tell you if you have super-user permission. Root Checker is a popular one. Simply downloading and running the app will tell you if your phone has super-user permissions.
Install a root management app
Rooting will make your phone more vulnerable to security threats. Installing a root management app will give you more peace of mind. Normally, every app that requires rooted privileges will ask for your approval. This is where root management apps, such as SuperSU, come in. SuperSU lets you allow or deny sites’ requests for super user permission. It will then keep track of the permissible apps and automatically grant permission next time you use the app. SuperSU will also keep track of how many times an app requests to root.
