What Is Rooting?

Rooting is a process of giving the device user the superuser permissions or the privilege to access the device system files

Why Is It Needed ?

Rooting allows elevated system access.
It enhances the engineering control over your phone.
You can decide what your phone can do .
The appearance of your device will be in your hands
(ultimately customisable).
All aspects of the operating system can be customised with
the only real limitation being the level of coding
expertise.
Rooting also gives you access to the device's system files.
It is done to remove the restrictions that the device
hardware manufacturer and the carriers have put on the
device
