Deleting unnecessary applications on Samsung Galaxy A51 is a task that only seems simple. Even after standard removal through the menu, many apps leave behind a cache, data in memory, or do not disappear from the system at all if they are pre-installed. In this article we will look at all possible ways: from basic to advanced, including working with ADB and hidden settings One UI.

The peculiarity of Galaxy A51 (model SM-A515F) is that that it comes with an extensive set of proprietary applications Samsung and services Googlethat cannot always be removed using standard methods. We will show you how to bypass these restrictions without risking system stability, and we will explain why some apps cannot be removed without consequences for the operation of the smartphone.

  • Install ADB on your computer:
    • Download Platform Tools from site Android Developers.
    • Unpack the archive into a convenient folder (for example, C:\adb).
    • Run the command line: 
      cd C:\adb

      adb devices

      (the name of your device should appear).

    • Delete the application: 
      adb shell pm uninstall -k --user 0 com.package.name

      (replace com.package.name with the real package name).

    To find out the application package name, use the command:

    Before deleting system applications via root create a full backup of the partition /system using TWRP. This will allow you to restore your smartphone even in case of critical errors.

    • 📁 Configuration files in /sdcard (for example, folders with the name of the application).
    • 🔗 Registry entries Androidthat can slow down the system.

    To completely clear traces:

    1. Use the built-in tool Settings → Device maintenance → Memory → Clean.
    2. For deep cleaning, install SD Maid (requires root for complete access).
    3. Check the folder /sdcard manually through any file manager (for example, Solid Explorer).

    If you deleted the application via ADB, residual files can be found with the command:

    adb shell ls /data/data/ | grep"package_name"

    • 🔧 Try roll back the application to the factory version via ADB: 
      adb shell pm install -r --downgrade /path/to/original.apk
    • 🔄 If there is a problem in Knox, check the status via #0# (in the dialer). If Knox: 0x1, recovery is only possible through flashing.
    • 📥 Reflash the smartphone to clean firmware (for example, LineageOS, if official methods do not help).

    FAQ: Frequently asked questions about deleting applications on the Galaxy A51

    Can I delete Bixby completely, and not just disable?

    Yes, but only through ADB or with with root access. To do this, remove the packages:

    com.samsung.android.bixby.agent

    com.samsung.android.bixby.wakeup
    

    com.samsung.android.app.spage
    

    com.samsung.android.bixby.service

    After removal, the button will disappear Bixby, but the voice assistant Google will remain operational.

    Why, after deleting the application, does it appear again after updating system?

    This happens because some applications (for example, Facebook or Netflix) are built into firmware as system ones. When updating One UI they are restored. To avoid this, use ADB to remove firmware for all users:

    adb shell pm uninstall -k --user 0 com.package.name

    Or disable automatic updating of system applications in Google Play.

    How to find out which application takes up the most space?

    Go to Settings → Device Maintenance → Memory → Memory Analysis. A list of applications is displayed here, sorted by space occupied. Alternatively, you can use utilities like DiskUsage (available in Google Play).

    Can I delete Google Play Services?

    No, it is a critical system component.. Deleting it will lead to the inoperability of most applications, including Google Play, Gmail and other services. The maximum that can be done is to disable automatic updating through ADB:

    adb shell dumpsys package com.google.android.gms | grep"version"
    How to restore a deleted system application?

    If the application was deleted via ADB without root, you can restore it by flashing the smartphone or with the command:

    adb shell cmd package install-existing com.package.name

    If used root, restore the backup via Titanium Backup or reinstall APK manually (for example, by downloading it from APKMirror).
