The KingRoot one click root app is available to download for devices running Android 4.2.1 Jelly Bean. Once you install the KingRoot Android 4.2.1 Jelly Bean APK, you will have three new apps available from your device’s app drawer. You will have one under the same name (KingRoot) and two others: King User and King Master. The King User is the app you want to access if you want to unroot the device. You will see what to do once you enter the app for that. The KingUser is also useful for remove system apps and disabling the auto-start of apps. King Master improves the device performance by archiving notification and making app hibernation automatic.

Once you understand how the KingRoot rooting tool works, it’s easy to use. Just browse the list of supported devices from the list below and the app will work for all Android software version that is currently being used. It works for the popular Android KitKat, Android Jelly Bean, Android Lollipop, Android Ice Cream Sandwich and Android Gingerbread. Only roughly 0.4% of Android devices are currently running Android Froyo. If you are one of those devices, the KingRoot universal one click rooting tool works for them too.


Arguably the best part about the KingRoot app is that it is near impossible to brick your device when you use the tool. With an average rooting guide, you must at least apply the steps and see if it works. It’s a big risk since it might not work and brick your device. With the KingRoot app, you just click the button, and it checks to see if your device can be rooted first. If the answer is no, then you can just delete the app and not use it. If the answer is yes, then you can proceed and open the system internal with the root access you always wanted to have on your device.

While the KingRoot one click rooting APK is easy to use, it’s still granting access to the root file system. Whenever you have access to the root file system, you are leaving your device vulnerable. The two main reasons for the vulnerability include the fact that you can delete necessary files from the file system, and you exit the device more open to potential malware attacks if you download a bad file. So, now that you know that, you should backup your data before starting the guide. As long as you do backup the device, you should have no worries restoring that data again later, no matter what you delete by accident.

What Is Rooting the Android Operating System?

When you buy a new smartphone, you might not know it, but the Android operating system is in a “locked” state. For the most part, it will not make much difference to you: most apps are still available to use, and there are benefits to this locked state such as better security. When you root the Android operating system, you are gaining full administrative rights over the OS.

Why Would You Want to Root Android?

Gaining full administrative rights over the operating system has some perks to some people. For example, out of the millions of applications available on Google Play, some of them will not be able to run on your device unless it has root access. Until you have a specific need for wanting Android rooted, you probably want to leave Android as it comes out of the box. But if you need to unlock an app, then that is when you want to look into rooting methods. Using more apps is only one example of why you may want root access, here is the full list of benefits:

  • Unlock more applications. Some of the apps available for Android cannot run unless you have root access. This is because the app’s features cannot run without the root permissions because the features require the full system access before they can be useful.
  • Better battery life. Smartphones are great, but they have one caveat, which is each time you recharge the battery, it loses some of its overall lifespan. That means smartphones, in general, do not make great investments, and if your weekly paycheck is low, you will want to limit the number of smartphones you go through. One of the ways you can do that is by removing bloatware and creating a better battery life.
  • Bolster performance. If you are the budget-conscious shopper, you may want to increase the device’s performance. This can be done by removing the bloatware as well. The more processes you have running, the more memory that is used. By removing some of the apps, it can help lighten the load on your hardware.
  • Customize Android with themes. With root access, you can download and install any theme that’s at your disposal. That includes any customized theme you can find.

What Are the Risks of Rooting?

If you are buying a smartphone that is not running iOS, then it is probably the Android operating system that you want running as the ideal software to pair with your shiny new hardware. It is, in fact, the Android OS that offers you the chance to customize the OS considerably more than iOS: custom themes, run any app you know about, the works. For many users, the “openness” of an operating system is important, because it offers them more freedom which means running into fewer problems with their investments. But there is a reason iOS likes a far more locked approach: the ability to customize is not for everyone, and if you do not know what you are doing it can lead to a lot of problems which can define your time with the OS rather than freedom.

With power (full admin permissions) comes greater responsibility. Here are some of the main risk factors when it comes to rooting:

  • Malware becomes a larger threat. You might read the occasional news article about how new malware is wreaking havoc in parts of the world on Android. But the Android operating system with root access becomes considerably more vulnerable to exploits because applications are no longer prisoned off in their own sandbox environments. This means if you accidentally download malware, it can do more damage because it can spread throughout the operating system and even jump into other applications and potentially view sensitive data.
  • You can accidentally brick the smartphone. There is always a chance that you end up bricking the smartphone before you had the opportunity to use it with root access. That is because if you are going to brick it, it is going to happen during the rooting process.
  • You may void the warranty. Most manufacturers do not allow you to root the Android operating system and still get to bring it in for repairs under warranty. Whether they are legally meant to do that or not is another question, but it is now common knowledge that most do not want to help you if they find out you have unlocked the OS with root access.

It does not matter if you flashed SuperSU from a custom recovery like TWRP and ClockworkMod or installed a one-click rooting tool like KingRoot and VRoot, they both mean you are now the root user and have full privileged control over the Android operating system. Having root access allows you to install any apps that you want to install. That means you have free range over the thousands of additional apps called root apps that would not run on your system up until now. You probably know many of these names already: Titanium Backup, Tasker, Greenify, ROM Manager, Viper4Android and so forth. It is up to you what is installed and up to you how your device now runs. If you want a better music experience, then you want to install Viper4Android. If you did not like any of the backup apps that were available before today, then Titanium Backup is what you want to install. If you think you want to be more like Data from The Goonies and that you have some feature ideas that were not included in the stock version of Android then Tasker is the app to try. The Google Play Store is riddled with these root apps that do nothing but help you create the device you want to have.

One thing you need to be wary of though is the fact that Google Play does not show you a list of what the root apps are and the root apps that are trending like it does with the stock apps. You need to open the Google Play Store app with the knowledge or already knowing the names of the root apps that you want to install. We are here to help you with this. All you need to do is check out our list that includes some of the best root apps for the Android operating system to be found in the world and then writes down the names, so you do not forget them. is the official KingRoot website. Beware of imitations, particularly on the Google Play Store, from apps that are labeled ‘KingRoot’ but not made by the real KingRoot team. Those apps likely won’t root your devices and could cause you harm.
