Android is a mobile operating system that based on Linux and the root user is an Administrator user, which has all permissions to access to the entire Android operating system (OS). Like other mobile OS, Android limits the app working in the sandbox, to protect your Android device from threats as well as exploitation.
On a regular Android device, you do not have root access, but the root user always exists in the system. You can not access to the root user with any built-in feature, so “rooting” is an only way to access and use the root user account.
Basically, rooting an Android device is the same with jailbreak an iOS device, allows apps to work with more access, permissions and low-level system. With the root user access, you can run a firewall on your Android device, as well as remove bloatware, enable tethering internet, manually backup app settings and use a lot of tweaks. If you want to use a specific Android app and it’s required root access, then you need to root your Android device.
What You Should Know Before Root Your Android Device?
Typically, Google and manufacturers do not recommend you to root Android devices because it makes your Android OS is weaker. After rooted, most apps are able to working out of the sandbox and could abuse root privileges and snoop on other Android apps. For example, if you are using Google Wallet, someone can try to attack your Android devices and exploit your Google Wallet account.
In terms of some manufacturers, you will lose warranty of the device if it’s rooted. The root process is not actually damaging the hardware. You are also able to unroot the device by just restore the stock firmware, and manufacturers will not able to know if it’s been rooted or not.
Basically, rooting is a safe process, but if you mess something up, then you can’t expect a free fix from warranty service. So make sure you clearly know what you will do in the next step or know how to restore your Android device in case it got errors. I would suggest you backup your data and important files before root your Android device. If you don’t know how to backup the device, then the simplest way is using Android file transfer to copy your important data and files.
