Have you rooted your Android phone? you can’t still be always sure that the process happened correctly, and the device is actually rooted or not. Sometimes, the rooting tool which you used might show that the process happened successfully, but the administrator or root access is not available when you try to install any custom firmware on the device.
For checking this, there is an application called the “Root Checker” app which does the job of checking for root simpler and easier. The most common binary used to gain the root access in an Android phone is the su binary, and what this Root Checker app would do is to check whether that binary is in a particular location on the device. This application will also confirm the proper permissions and flags on the su binary in addition to testing the access granted by the su binary.
The best thing about the Root Checker application is that you don’t need to have any skills or knowledge about rooting, about the binaries or anything, and you just need to install the app and check for the status of the device.
The process of confirming root access is sometimes known by other terms such as, gaining superuser access or gaining administrator access. Root Checker covers all these terms as they relate to one core function, being able to execute commands with root access. If you have rooted the device, and if the SuperUser or SuperSu are properly installed in it, you will be prompted by the Root Checker app whether to accept or deny the root access from it, and after you accept it, the checking for the root would be done.
As shown in the above screenshots, the Root Checker app is quite simple to understand and use to check if your Android phone is rooted properly or not. This app is available for free download from the Google Play Store – Link.
