Modern smartphones, including the popular model Samsung Galaxy A51are inevitably filled with many apps over time. Some of them are preinstalled by the manufacturer, others are downloaded by the user during operation. Over time, some of this software becomes useless, taking up precious space in the internal memory and consuming processor resources in the background. Properly cleaning the device of unnecessary software is a key step to maintaining high performance of the gadget.
Owners of devices based on Android often encounter a situation where the standard uninstallation method does not work or the uninstall button is simply inactive. This is especially true for system utilities that the manufacturer considers important for the operation of the shell One UI. In this guide, we will look at all the possible ways to get rid of unnecessary apps: from simply dragging and dropping icons to using advanced debugging tools.
The methods discussed below will help you not only free up space, but also relieve the battery from unnecessary load. It is important to understand the difference between regular applications and system components, since the approach to removing them is radically different. Be careful when choosing objects to delete so as not to disrupt the stability of your operating system Galaxy A51.
Standard method of deleting via the desktop
The most obvious and fastest way to get rid of an unnecessary app is to use the main screen. The interface One UI from the company Samsung allows you to delete application icons directly from the desktop without having to go into deep menu settings. This method is intuitive and suitable for most user apps downloaded from the store Google Play.
To complete the procedure, you need to find the application icon on one of the home screen screens. Click on it and hold your finger for one or two seconds until a pop-up menu appears or enters edit mode. Depending on the firmware version, the interface may differ slightly, but the logic of action remains the same for the entire line. Galaxy A.
After entering the editing mode, a toolbar will appear at the top of the display. You need to drag the application icon to the area indicated as Delete or the trash icon. An orange highlight in the reset area will confirm that the action will be completed. Release your finger, and the system will ask you to confirm the operation.
If you see the inscription Delete in gray or absent altogether, this means that this application is a system one. In this case, the standard desktop method will not work and you will need to use the device settings menu. Do not try to use force or third-party launchers to bypass this limitation at this stage.
⚠️ Warning: Removing an icon from the desktop in some launchers may simply remove the shortcut, but leave the application itself in memory. Make sure that the confirmation menu says “Delete application” and not “Remove from the main screen.”
Uninstallation via the system settings menu
The settings menu provides more detailed control over the installed software. Here you can see a complete list of all apps, including those that do not have desktop icons. This is the most reliable way to manage memory on Samsung Galaxy A51, which also allows you to clear the cache before deleting.
To access the list, open the section Settings and scroll down to the item Applications. The list that opens will display all installed apps, sorted alphabetically or by frequency of use. You can use the search bar at the top to quickly find a specific application by name.
Select the desired application from the list. On the application information screen, you will see several control buttons. If the app can be removed, the button Delete will be active and highlighted. Clicking on it will launch the standard uninstallation process with a confirmation request from the security system. Sometimes it's useful to reset an app's data before uninstalling it to make sure it doesn't contain important files that you might have forgotten to save. However, for most user apps, this is not a required step before uninstallation. Android.
The function is available in the same menu Clear data And Clear cache. Sometimes it's useful to reset an app's data before uninstalling it to make sure it doesn't contain important files that you might have forgotten to save. However, for most user apps this is not a required step before uninstallation.
☑️ Check before uninstalling
Managing applications via Google Play Market
Digital content store Google Play does not serve only for downloading new software, but also for managing already installed ones. This method is convenient because it allows you to remove apps even if you cannot find their icon on the desktop due to a launcher crash or hiding the shortcut.
Launch the application Play Market on your Galaxy A51 and click on the profile icon in the upper right corner of the screen. In the drop-down menu, select Manage applications and device. Next, go to the tab Overview or Installedto see the list of apps taking up space on your device.
Find the desired application in the list and click on it. The app page will open, where instead of the button Open or Update the button Deletewill be displayed. This method is especially useful for mass uninstallation: you can tick several applications at once and uninstall them with one command.
The advantage of this method is that Google Play clearly separates user and system applications. If there is no delete button even here, it means that the app is built into the firmware at a deep level and requires special rights to disable it. Here you can also see the date of the last update, which helps identify software that has not been used for a long time.
Removing and disabling system applications
Smartphones Samsung often come with a set of pre-installed software that cannot be removed using standard methods. Such apps include services Microsoft, social networks, proprietary utilities Samsung and some system components. A function is available for them disabling, which has an effect similar to deleting.
When disabled, the application stops starting, disappears from the list of active processes and does not consume battery power. The app files remain in memory, but they are compressed or hidden, no longer affecting system performance. This is a safe way to deal with bloatware (junk software) without the risk of damaging the firmware.
To disable a system application, go to Settings → Applications, select the desired item and press the button Disable. The system will warn you that replacing the application may cause other apps to not work properly. If you are confident in your actions, confirm the operation.
| Application type | Uninstall option | Recommended action | Impact on the system |
|---|---|---|---|
| Custom (from Play Market) | Full removal | Feel free to delete | Absent |
| System (Samsung/Google) | Disable only | Disable if not used | Minimum |
| Critical (Android system) | Locked | Do not touch | High (risk of failure) |
| Device administrator | Removal of rights required | Remove rights, then delete | Depends on the function |
⚠️ Attention: The interface and available functions may vary slightly depending on the version of the Android operating system and the One UI shell. The manufacturer regularly updates the software, so the location of menu items may change.
Which system applications are safe to disable?
Safely disable: Facebook, Netflix, Microsoft Office (if you don't use it), Samsung Pass (if you don't use passwords), Bixby (if you don't use the voice assistant). It is not recommended to disable: Samsung Account, Google Play Services, Android system interface, Device Manager.
Problem with device administrator rights
Sometimes the user is faced with a situation where the button Delete is inactive, although the application is not a system one. Most often this is due to the fact that the app has been granted extended rights device administrator. Antiviruses, remote control applications, and some corporate clients have these rights.
As long as an application has administrator status, the system blocks its deletion for security reasons. To uninstall such a app, you must first revoke its privileges. This is done through a special section in your security settings Samsung Galaxy A51.
Go to menu Settings → Biometrics and security → Other security settings. Find the item Device administrator applications and click on it. In the list that opens, you will see all apps that have special rights. Uncheck the box next to the desired application and confirm the action by pressing the button Deactivate.
After removing administrator rights, return to regular application menu. The delete button should now become active. If the problem persists after deactivating the rights, try rebooting the device and repeating the procedure. In rare cases, complete revocation of access rights in the developer menu is required.
Advanced method: removal via ADB
For advanced users who want to completely clear Samsung Galaxy A51 of any firmware, including non-removable system components, there is a method of using debugging by ADB (Android Debug Bridge). This method requires connecting the smartphone to the computer and installing a special driver.
First you need to activate developer mode. Go to Settings → Phone information → Software information and quickly click 7 times on the item Build number. After a message appears that developer mode is enabled, return to the main settings menu and open a new item Developer options.
Turn on the switch USB debugging. Connect your phone to PC with a cable. On the computer where the toolkit is installed Platform Tools, open the command line and enter the command to test the connection:
adb devicesA request will appear on the smartphone screen to allow debugging from this computer. Confirm it. Now you can remove applications for the current user (without completely removing them from the system, which is safe) using the command:
adb shell pm uninstall -k --user 0 package nameTo find out the package name, use the command adb shell pm list packages. This method allows you to remove even those apps that are hidden from the user in the standard interface. However, it is worth remembering that incorrect removal of critical system packages can lead to bootloop (cyclic reboot).
⚠️ Attention: Using ADB requires technical literacy. Removing system packages responsible for the operation of the interface or communications may make the phone unusable without flashing it. Act only with those packages whose purpose you know 100%.
The ADB method allows you to remove almost any application, but it is not necessary for the average user. Standard Samsung Galaxy A51 tools are enough to keep the system clean in 99% of cases.
Frequently asked questions (FAQ)
Why does it appear again after deleting an application?
Some system applications Samsung or Google have a self-healing mechanism after a system update or reset. If you simply disabled the app, it may reactivate with a major firmware update. This can also happen if the application is part of an ecosystem (for example, Google Play services).
Does deleting an application free up space on the SD memory card?
By default, applications are installed in the internal memory. If you previously transferred the application to a memory card (the function is not available for all apps), then deleting it will free up space on the SD card. However, modern versions Android on Galaxy A51 limit the installation of applications on external drives, so most often only internal memory is freed.
Is it possible to restore a deleted application?
Yes, if you deleted a user application from Google Play, you can always download it again from the store by searching by name. Your download history is stored in your account. System apps that you have disabled can be re-enabled in the Settings menu. Data stored inside the application is irretrievably lost during standard deletion unless a backup copy has been made.
Is it safe to use third-party cleaning apps (Clean Master and analogues)?
Using aggressive “cleaners” on modern smartphones Samsung is often unnecessary and can even cause harm. The built-in optimization system One UI independently manages memory and processes. Third-party utilities can intrusively show ads, consume resources and delete the cache that the system planned to use to speed up the work, which ultimately will only slow down the device.
What to do if the phone says “Not enough space” when uninstalling?
This is a paradoxical but possible error that occurs when the file system crashes or if the application is in an update state. Try restarting your smartphone and trying again. If it doesn’t help, go to the application menu and first press Clear data, and then Delete. In extreme cases, a remote system update may temporarily block memory operations.
