How to uninstall the system applications on Android: ways to uninstall unwanted programs

As you know, the mobile OS (as well as any) consists of many individual components, each of which performs a different task. Some are responsible for the sensors, the second is used for the correct operation of the Wi-Fi modules, and the third, and even created to throw in the interface obtrusive advertising. So, these components are called system components and are already in memory at the first start. We will tell you how to remove system applications on Android phones.

Preparing to uninstall built-in applications

So, let’s warn right away about the possible dangers, in order to avoid undesirable consequences. The Android OS has many pre-installed system applications. Some of them don’t seem to play any role, or even harm the device, draining it faster and taking up memory. In fact, all of these applications not only do their job, but also act as dependencies for other programs.


That is, if you remove one program, others may not work anymore. So we recommend that you take a detailed look at the objects you are uninstalling before you start the process. We have warned you and hope that you will not make a fatal mistake which can only be solved by reflashing.

Some of the methods described below require root rights. You can get them through the Kingo Root application. However, as practice shows, it does not work on all devices, especially if they have a locked bootloader. In this case, search the Internet for ways to root your device (specifying the model and preferably the Android version).


Also before uninstalling, we recommend checking whether you can disable the application without uninstalling it. This method is much more humane and safer compared to uninstalling the program files. In addition, if you delete user files and the cache of the disabled application, the program will occupy only a few kilobytes of memory and will not affect the process of using the gadget. Additionally, we recommend making a data backup in case of an unfortunate outcome.

Deletion methods

There are several ways to perform the task. Most of them require a computer and a cable that connects the phone and computer (most likely you have it USB – type-c). Let’s look at the most basic removal methods.


ADB App Control

Let’s start, perhaps, with one convenient and versatile program that allows you to remove the applications on the phone from the computer through the ADB interface. As experience shows, this method (at least) is great for Samsung Galaxy phones, where there is a lot of “system” junk. Algorithm of actions for working with the program:

  • Go to and download the program to your computer.
  • Install and run it.


  • Connect your phone to your computer with a wire.
  • Open the phone settings and go to “About device”.


  • Tap the build version up to 8 times. It should say “You are now a developer”. If it doesn’t appear, tap on the other items.
  • Go to the main menu and find the “Developer Tools (or Menu)” subsection.


  • Open it and enable the item “USB Debugging”.


At this point, only setup preparation is complete. Now try to open the program and update the device list. The software should detect the device. Notice that there will be a “Find Unwanted Apps” button on the right-hand menu. Select it first. Usually these are unnecessary Google and Facebook services on Android.

Once found, the user can delete or disable the selected services. Such an operation can be performed with each application. The application, in addition, offers a wide range of functionality to configure and manage the gadget. However, it works at the system level, which can lead to consequences if used incorrectly.

Android Debug Bridge

This service also uses ADB to work with the phone. True, it is more official and is used by developers of mobile software. It also allows you to remove even “native” programs. Officially, the program is distributed along with the developer environment Android Studio, which does not spare the “iron” of the computer. However, there are separate components on the Internet. The application only works in console format. Algorithm of actions:

  • Download the client.


  • Unzip it and open the adb.exe file.


  • Open the console. Enter the command “adb devices” to make sure the device is detected.
  • Type “adb usb” to start the USB connection.


  • Type “adb uninstall” to uninstall the application. The last word must be removed and changed to the name of the desired program. You can read it in the “Applications” section of the gadget settings.


This method is more complicated, because you need to memorize commands and manually search for undeleteable files. But it is faster, because the application above often hangs. It’s a pity that this method is problematic to manage the autoclicker screen on the phone (which you could organize in the previous application), but it’s not critical.

Through the PC

There is another way peculiar to phones with an official PC app. For example, for Xiaomi it is miAssistant. Install it and run it to search for pre-installed programs. By the way, it is much safer to clean through official applications, but they do not always provide this functionality. For example, standard client (non-service) programs are easy to remove with official software, but factory adware is not.


What to do after uninstalling firmware on Android

The deed is done, and the annoying software is gone. The first thing we recommend doing is a full test of the device to find faults immediately and understand what caused them. For example, during the experiments we noticed that after automatically switching off supposedly unnecessary programs, the Google assistant and the newsfeed were disabled. If a feature stopped working, then by experimenting, turn the disabled apps back on.
