Rooting a phone refers to the process of gaining access to the administrative control over the commands and functions of the operating system of the phone. Rooting is typically done on Android devices and also works on tablets and other devices that run on Android operating systems.
Rooting is usually done to overcome inherent limitations that are put in place by carriers and device manufacturers. Rooting is also referred to as root access, and it allows the device holder to install updated versions of the operating system, save battery life by freezing or disabling battery draining applications, alter system settings, and access specialized applications that require root access. While rooting a phone has many benefits, in almost all cases it voids manufacturers' warranties.
