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 through the su binary with root access.

If the Superuser management applications (Super SU, Superuser, etc.) are installed and working properly, these applications will prompt the user to accept or deny the root access request from Root Checker. Accepting the request will allow Root Checker to check for and confirm root access. Denying the request will result in Root Checker reporting no root access
