ANDROID ROOTING, PROCESS, LIMITATION AND MANUFACTURER'S REACTION
From WIKI
Rooting is the process of allowing users of smartphones, tablets, and other devices running the Android mobile operating system to attain privileged control (known as "root access") within Android's sub-system.
Rooting is often performed with the goal of overcoming limitations that carriers
and hardware manufacturers put on some devices, resulting in the
ability to alter or replace system applications and settings, run
specialized apps
that require administrator-level permissions, or perform other
operations that are otherwise inaccessible to a normal Android user. On
Android, rooting can also facilitate the complete removal and
replacement of the device's operating system, usually with a more recent
release of its current operating system.
As Android derives from the Linux kernel, rooting an Android device gives similar access administrative permissions as on Linux or any other Unix-like operating system such as FreeBSD or OS X.
