Literally, the "Root" symbolizes the "beginning" or "birth". So, root acess refers to entering the place where everything comes from. When it comes to Android rooting, It means accessing the account where users can have privilages to change the system files and command in Android operating system. As of now, most Android users are aware of Android rooting and a considerable number of users have tested various rooting methods and tools. In here I am trying to explain the technical side of Android and you can have some related information along with the key information.

What Is Android

Android is the mobile operating system which is developed by Google. Google released the initial version of Android in 2008 and currently, it has reached to its 9th edition Android Pie 9.0. Currently, there are a few leading and competitive mobile operating in the world and Android is the most popular mobile operating system in the world by now. Initially, Android was designed for smartphones with touchscreen and recently it was designed to use on Android Tv, Watches and Cars with different interfaces.

Technical Side Of Android Operating System

Android is based on Linux Kernel and officially it comes as an open-source mobile operating system. It means users and developers are free to modify the system and distribute it based on any purposes. As the basement of Android, Linux provides higher security features to protect the Android system. Basically, Android is fully protected by default Linux kernel security and additionally, Android is protected by using inter-process communication (IPC) facility. The key intentions of these security features are to prevent harms from rogue apps to other apps.

Rooting Android 

Officially, In Android, only Android Kernel and some of the core applications run on root permissions. Because Android does not prevent any user or application with root permission. It allows any user or application to modify the system, application or kernel. Generally, Root has acess to all applications and all application data. If an Android user changes the default permission to grant the acess to app or programme that is not approved by the Android system, it may decrease the security of the system. But Android developers need the ability to modify the device that they are using to work on the Android platform. That is why most Android smartphone comes with unlockable boot loaders. After unlocking the bootloader users are able to install alternative operating systems. Some of these alternative operating systems allow users to gain root access. In addition to this method, some device holders can install a new operating system that provides root privileges. In this case, bootloader erases any existing users data on the device as the part of bootloader unlocking step. If you are going to have Root access via exploiting a kernel bug or security hole you can save your user data on your device bypassing this protection. This is the most popular and common method to have root acess.

 Exploiting A Kernel Bug Or Security Hole

The best way to have root acess by exploiting a kernel bug or security hole is to use the one-click rooting tool. Because it simply exploits the relevant kernel bug or security hole itself and grants root acess for the application that we need. When a Kernel bug or security hole is found on the Android, system developers start to work on it and create rooting tools to acess the core part of the Android system where the system files and command has been placed. Since the Android patches these bugs the same rooting tool cannot be used on every Android version or Android device all the time. When a new Android version is released it comes with higher security and developers needs considerable time to launch a new rooting tool. That is why we cannot find out successful rooting tool as soon as the latest Android version is released. If you are one of Samsung Galaxy user you can refer to learn the way to exploit kernel bug on Galaxy devices.

What Are The Purposes Of Android Rooting

By default, manufacturers keep root directory (Core of system) beyond the users since users may delete the essential system files which have been stored in the root directory. The root folder is located in the deepest level of the Android system and it has been separated using an artificial barrier. As mentioned above, the Root folder contains the essential system files. So, if you can acess the root folder you can change everything in systewise. As an example let's consider Google calculator. By default, you cannot delete Google calculator which comes as a pre-installed app. But you can acess /system/apps/ folder in the root directory manually after rooting your device and delete the app. Likewise, you can install third-party apps, install modified themes, games, custom ROMs and do many more things after rooting your device.


Android Rooting is the gate to customize your Android as you want and feel the full potential of your device. Actually, you may feel uncomfortable when trying to understand the technical side of rooting. But practically you can root your device easier since the whole the mechanism is done automatically. But In my opinion, you need to get to know what is happening to your device when rooting at least in simple words.
