With each update of the operating system or after purchasing a new smartphone, users are often faced with a situation where the internal memory of the device quickly fills up. Not only your personal files are to blame for this, but also pre-installed apps that you have never used. Developers and device manufacturers often install a whole bunch of system utilitiess that take up space and consume CPU resources in the background. This phenomenon is known as bloatware.
Free space is critical for stable operation Android. When the storage is full, the smartphone begins to work slower, there are delays when switching between tasks, and new updates may simply not download. Fortunately, modern versions of the mobile operating system provide enough tools to clean your device of digital junk. You do not need to be an experienced programmer or obtain superuser rights to solve this task.
In this article we will look in detail at how to remove an unnecessary app on Android from a photo, as well as how to get rid of other unnecessary apps using standard methods and using advanced tools. We will look at the difference between regular deletion and disabling, and also touch on security issues when working with system components.
Standard deletion of user applications
The easiest way to free up space is to remove apps that you installed yourself from the store Google Play. The operating system allows you to do this in just a couple of touches of the screen. However, many users are not aware of the hidden menu functions that speed up this process significantly.
First, find the icon of the unnecessary app on the main screen or in the all applications menu. Tap and hold the icon for one to two seconds. In the context menu that appears, select Delete or drag the icon to the top of the screen, where the trash can will appear. The system will ask you to confirm the action, after which the app will be completely erased from the device along with its cache and data.
If you want to do a mass cleanup, it is better to use the phone settings. Go to section Settings → Applications → Manage applications. Here you will see a complete list of installed software. By clicking on a specific list item, you will be taken to the information screen, where the button Delete will be active for all user apps. This is the most reliable method that eliminates accidental clicks on the desktop.
⚠️ Attention: Before deleting instant messengers or banking applications, make sure you remember your login passwords. After re-installation, you may need to fully verify your identity or restore access through support.
☑️ Preparing to clean your smartphone
Some apps may resist uninstallation if they have active device administrator rights. In this case, the system will generate an error. You will need to go to the security settings, find the section Device administrator applications and uncheck the desired app. Only after this the standard removal procedure will work correctly.
Disabling system applications and Bloatware
The situation becomes more complicated when it comes to pre-installed software from the smartphone manufacturer or telecom operator. The Delete button for such apps is often inactive (gray) or absent altogether. This is done to protect the system from accidental damage, but turns the phone into a repository of unnecessary garbage.
Fortunately, in modern versions Android (starting from 7.0 and higher) a forced stop and shutdown function has appeared. Although the app file physically remains on the system partition, it stops running, updating, and consuming RAM. For the user, this is tantamount to deletion, since the icon disappears from the screen, and space in the user storage is freed from updates and data.
To disable such a app, go to Settings → Applications. Find unnecessary system services in the list, for example, extra games or branded shells. Click on it and select the button Disable. The system will warn you that other applications may not work correctly. If you are sure that this component is not critical for the operation of the phone, confirm the action.
- 📱 Disabling removes all application updates, returning it to the factory version.
- 🚫 A blocked application does not will be displayed in the menu and will not be able to run in the background.
- 🔄 You can always turn the application back on through the same settings screen.
There is a category of apps that cannot be disabled using standard means. This often concerns services Google or deeply integrated components of the manufacturer's shell. Trying to remove them through the settings will simply not be successful. In such cases, the use of a computer and USB debugging is required, which we will discuss in the following sections.
What is the difference between deleting and disabling?
When deleting, the .apk file is completely erased from the device’s memory. When disabled, the file remains on the protected system partition, but is marked with the "disabled" flag. The system ignores it when loading, saving resources, but the space in the system partition (which is not available to the user) continues to be occupied by the basic version of the application.
Removal via computer using ADB
For advanced users who want to clear their smartphone of any unnecessary code, there is a tool ADB (Android Debug Bridge). This is an official utility from Google that allows you to control your device from your computer via the command line. This method allows you to remove even those applications that are hidden from the user in the normal interface.
Before you start, you need to enable developer mode on your phone. Go to Settings → About phone and quickly click on the item Build number seven times until a notification about activating the mode appears. Then in the new menu For developers turn on the item USB debugging.
Connect your smartphone to computer cable. The platform must be installed on the PC ADB. Open a command line or terminal in the folder with the utility and enter the command to test the connection:
adb devicesA request for permission to debug from this computer will appear on the phone screen - confirm it. If the serial number of the device is displayed in the terminal, the connection has been established successfully. Now you can start deleting. First you need to find out the exact package name of the application you are uninstalling. This can be done with the command:
adb shell pm list packagesThe list will be huge, so it is better to use a search by name. For example, if you need to remove Facebook services, look for lines containing facebook. Once you have the exact package name (for example, com.facebook.katana), use the uninstall command for the current user:
adb shell pm uninstall -k --user 0 package name⚠️ Attention: The command
uninstallvia ADB uninstalls the application only for the main user (user 0). When you reset your phone to factory settings, apps deleted in this way may return, since they physically remain on the system partition.
This method requires caution. Removing critical system components such as com.android.phone or services may cause the phone to become unbootable or lose connectivity. Always check the purpose of the package on the Internet before entering the uninstall command.
Using specialized cleaning software
If working with the command line seems too complicated for you, there are graphical shells that automate the process of uninstalling system applications. One of the most popular and safe apps is Universal Android Debloater. It works based on ADB, but provides a convenient interface with a list of applications and explanations.
The app automatically detects the model of your device and offers a list of apps recommended for removal. It marks applications with colors: green - safe to remove, yellow - requiring caution, red - critical system components. This significantly reduces the risk of turning your smartphone into a “brick.”
To work with such software, you will still need to enable USB debugging, as described in the previous section. After connecting, the app will scan the device and display a list of installed software. You can select applications with check marks and press the button Uninstall to remove them. The interface is intuitive and does not require knowledge of the technical names of the packages.
Another option is cleaner applications installed directly on the phone, such as NoBloat or analogues. However, for their full operation, they often require root access. Obtaining superuser rights allows full access to the system, but voids the warranty on the device and can disrupt the operation of banking applications due to security protection.
| Cleaning method | Necessity of Root | Risk breakdowns | Efficiency |
|---|---|---|---|
| Standard deletion | No | Absent | Low (custom only) |
| Disconnection in settings | No | Minimum | Medium (hides bloatware) |
| ADB (command line) | No | Medium | High (complete removal for the user) |
| Third-party software with Root | Yes | High | Maximum (access to everything) |
Before large-scale system cleaning using ADB or third-party apps, create a full backup of your data. In case of an error, this will allow you to return the phone to working condition in a few minutes.
Analysis of the impact of applications on the battery and memory
Sometimes the problem is not the number of installed apps, but their activity. Some “extra” applications may not take up much space, but actively run in the background, draining the battery and loading the processor. You can identify such hidden resource hogs through the built-in statistics.
Go to the section Settings → Battery. Here you can see a graph of energy consumption and a list of applications sorted by consumption. If you see an application that you haven't used for a long time, but it's in the top 5 in terms of battery consumption, it's a good candidate for deletion or forced stop. Social networks and news aggregators often behave this way.
It is also worth checking your RAM usage. The section Settings → Memory (or in the developer menu Running services) displays how much RAM each application takes up. Heavy processes can slow down the entire device. Forcibly stopping such services through the app menu gives a temporary effect, so the best solution is complete removal.
Pay attention to application permissions. Go to your privacy settings and see which apps have access to your microphone, camera, or geolocation. If a simple flashlight or calculator asks for access to your contacts and location, this is a suspicious signal. It is better to remove such applications immediately, replacing them with more reliable analogues.
⚠️ Attention: The battery and memory settings interface may differ depending on the version of Android and the manufacturer’s shell (MIUI, OneUI, ColorOS). If you do not find the item you need, use the search in the settings by entering the word “Battery” or “Applications”.
Restoring deleted system components
What to do if, in the heat of the fight to keep the system clean, you deleted something important? For example, the keyboard disappeared, Wi-Fi stopped working, or settings disappeared. There is no need to panic, since most removal methods are reversible, especially if you did not obtain root access and did not physically erase the system partition.
If the application was disabled through the settings, restoring it is trivial. Just go to the list of all applications, find “Disabled” in the filter, select the one you need and press the button Enable. The app will return to the menu and start working in normal mode.
If deleted via ADB, the application can be restored with the installation command for the current user:
adb shell pm install-existing package nameThis command will restore the application from the hidden system reserve. However, if you have permanently deleted a system component (for example, formatted a partition), the only option is to reset the phone to factory settings (Factory Reset). This will return the device to its original state with all pre-installed software.
Most deletions via ADB are reversible until the first reset. The system stores the original APK files in a protected partition, allowing you to restore the phone to its functionality without flashing it.
Before performing any recovery actions, make sure that the phone is charged at least 50%. The process of reinstalling system components can take time, and a sudden power outage at this point is undesirable, although less critical than when updating the firmware.
Frequently asked questions (FAQ)
Is it safe to remove Google Play Services?
No, this is a critical component of the system. Removing or disabling Google Play services will lead to the inoperability of most applications, account synchronization, push notifications and the application store. The phone may become practically useless.
Will deleted applications return after updating Android?
Yes, with a major update to the operating system version (for example, from Android 13 to 14), the system can restore the default status of all system applications. You will have to repeat the procedure of disabling or uninstalling via ADB.
Is it possible to remove a system application without a computer?
Without root access and a computer, it is completely impossible to remove a system application. You can only disable it through the settings, which will hide the icon and stop processes, but the file will remain in memory. To completely remove it, you need ADB or superuser rights.
Why is the "Delete" button inactive for some games?
Most likely, this application is installed by the phone manufacturer as system software (bloatware). It has rights that protect it from ordinary deletion. Try using the method of disabling or deleting via ADB.
Will deleting applications clear space in the "System" section?
When you normally delete user applications, yes. Disabling system applications will not free up space in the System section because the base file remains in place. Only the space occupied by updates and data of this application is freed.
