Rooting Android Cellphones and Tablets

First we have to know what is the term Rooting?

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) over various Android subsystems.
Rooting is often performed with the goal of overcoming limitations that carriers and hardware manufacturers put on some devices. Thus, rooting gives the ability (or permission) to alter or replace system applications and settings, run specialized applications ("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.

Advantages

Advantages of rooting include the possibility for complete control over the look and feel of the device. As a superuser has access to the device's system files, all aspects of the operating system can be customized with the only real limitation being the level of coding expertise. Immediately expectable advantages of rooted devices include the following:

- Support for themes, allowing everything to be visually changed from the color of the battery icon, to the boot animation that appears while the device is booting, and more.

- Full control of the kernel, which, for example, allows overclocking and underclocking the CPU and GPU.

- Full application control, including the ability to backup, restore, or batch edit applications, or to remove bloatware that comes pre-installed on many phones.

- Custom automated system-level processes through the use of third-party applications.

- Ability to install a custom firmware (also known as a custom ROM) that allows additional levels of control on a rooted device.

Methods

Some rooting methods involve use of the command prompt and development interface called Android Debug Bridge (ADB), while other methods may use specialized applications and be as simple as clicking one button. Devices, or sometimes even different variants of the same device, can have different hardware configurations. Thus, if the guide, ROM, or root method used is for a device variant with a different hardware setup, there is a risk of bricking the device.

Should I root my Android Device?

Yes. No. Maybe. All three answers are perfectly valid. People have different reasons to want to root their devices. Some do it just because they can — they paid for the hardware and think they should be able to do anything they like. Others want to be able to add things that aren't there, like internet servers or be able to "fix" services that are there but don't work the way they would like them to work. People might buy a phone because they like the hardware, but hate the software and want to change it. Mostly, people root their phones because they simply want to get rid of the extra things on it that they don't want. Every one of these reasons — as well as any reason you might have that aren't mentioned here — are the right reasons
