What is root ? and what can it do to your android phone!?

What is root?
Ans:Root: The term “root” is a relic of the Linux world (Android runs on Linux). Gaining root access means gaining administrator or superuser access to the entire device, at its most basic level.

The Android phone you’re using right now is running in a sandboxed environment. Unlike your Windows PC or Mac, you can’t go looking around or messing with system files. You can only operate within predefined parameters that are defined by Google and your manufacturer. Root access is the way to break free.
In the simplest terms, rooting your Android phone means taking control of your entire device, right from the code that’s running the operating system. It is beautiful, dangerous, and super rewarding. Rooting gives you access to system files, folders, and system commands — things that are normally hidden from the user.

Once you have root access, you’ll be able to do things mere mortals can only dream of. You’ll be able to remove carrier bloat, update to the latest version of Android even if it’s not officially supported, and you’ll be able to mod every part of the software. But as our friendly neighborhood superhero always says: With great power comes great responsibility.

Which brings us to the question — is it worth it?

So lets know about it here

The Advantages of Root Access
It’s important to note that just gaining root access won’t immediately solve all your problems. Rooting will just give you the power to do so. Here are all the clear advantages of using a rooted Android phone.

Remove bloatware: You’ll be able to remove carrier or manufacturer bloatware that was preinstalled on your phone.

Better backups: You’ll be able to back up individual apps along with their app data using Titanium Backup. And a Nandroid backup will let you backup your entire operating system with just a tap.

Custom ROMs: If your phone is running slow, just switch to a custom ROM. It usually comes with the latest version of Android and the latest security patches. Most custom ROMs run on stock Android, so your phone will run much faster.

Extra apps and features: You’ll be able to run apps that aren’t available on the Play Store, and you’ll be able to tweak not just the software, but the hardware as well (by overclocking and underclocking the CPU).

Extended life: The HTC HD 2 is a legend in the rooting world. The phone was released in late 2009, but thanks to custom ROMs, it is able to run Android 7.0 Nougat seven years after its release. For you, a custom ROM could mean an extra year or two out of your current phone.

I will post it disadvantages too
