Rooting Completely explained

What is 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") within Android's sub-system and don't worry its legal to Root Mobile.

Risks Involving in rooting...

• You can turn your smartphone into a brick. Well, not literally, but if you screw up the rooting process, meaning the code modifications, your phone software can get so damaged that your phone will basically be as useless as a brick.Be careful!! 
• Your phone warranty turns void. Say you root your phone and some time after that, you experience a phone malfunction – hardware or software related. Because of the Android rooting, the warranty is no longer valid, and the manufacturer will not cover the damages.
• Viruses. Yes, even phones can get viruses. A common practice that people do with "rooted" phones is to flash their ROM's with custom programs. Whenever you make changes to the code of a software, you run the risk of introducing a virus.

Privileges in rooting...

Custom ROM's. This is the most powerful feature of "rooted" phones. There are hundreds of custom ROM's that can do anything from speeding up the processing speed of your phone to changing the entire look and feel of your phone.

Install "Incompatible" Apps. Sometimes, even Android isn't open enough to give you some of the features you want. now you can install that app.

Flash a Custom Kernel. The kernel is responsible for helping your apps communicate with the hardware of your phone, which means a custom kernel can give you better performance, battery life, and even extra features like Wi-Fi tethering (on unsupported phones), faster battery charging.

Extra Battery life Speed up your mobile. You can do a lot of things to speed up your phone and boost its battery life without rooting, but with root—as always—you have even more power. For example, with an app like SetCPU you can overclock your phone for better performance, or underclock it for better battery life. You can also use an app like Greenify to automatically hibernate apps you aren't using—perfect for those apps that always want to run in the background when you're not looking.

In the end, all of this boils down to one thing: you own your device, and you should be able to do with it as you please. Certain manufacturers and carriers try to keep that from happening, but with root access, you truly own your device and open yourself up to all the possibilities other parties try to block.
