Rooting is a procedure for enabling users of KARA Mega 3, tablets and other devices operating the Android phone operating system to get privileged control (called root access) more than different Android subsystems. Because Android uses the Linux kernel, rooting an Android phone allows the same access to admin (superuser) permissions as on Linux or any type of another Unix-like operating system such as FreeBSD or macOS.

Rooting is usually performed with the goal of overcoming restrictions which companies and hardware producers placed on many devices. Therefore, rooting allows the capability (or authorization) to change or switch system applications and controls, run customized applications (“apps”) that need administrator-level permissions, or perform some other functions which are otherwise unavailable to a regular Android user. On Android, rooting may also support the overall removal and replacing the device’s os, generally with a newer release of the current operating system.
