Removing System Apps (Bloatware) on Android Using ADB

🔧 1. Preparation

#

A. Enable Developer Mode & USB Debugging

#

1. Open Settings → About Phone
2. Tap Build Number 7 times until it says “You are now a developer”
3. Go back to Settings → Developer Options
4. Enable USB Debugging

B. Install ADB on Your Computer

#

Windows

#

1. Download Platform Tools from Google
2. Extract to a folder (e.g., C:\platform-tools)

Linux/macOS

#

# Ubuntu/Debian
sudo apt install android-tools-adb

# macOS (via Homebrew)
brew install android-platform-tools

C. (Optional) Install Package Name Viewer

#

1. Open Package Name Viewer on Play Store
2. Tap Install

📋 2. View Installed Apps & Package Names

#

A. Using ADB (Command Line)

#

1. Connect your phone to your PC via USB

2. Open Command Prompt/Terminal in the ADB folder (cd C:\platform-tools)

3. Run:

   adb devices  # Make sure device is detected
   adb shell pm list packages  # List all installed apps
   

   • Filter vendor apps (example Samsung):

     adb shell pm list packages | grep 'samsung'
     

   • Filter Google apps:

     adb shell pm list packages | grep 'google'
     

B. Using Package Name Viewer (Easier Option)

#

1. Open the Package Name Viewer app

2. The app will show:

   • App Name
   • Package Name (example: com.facebook.katana for Facebook)
   • App Version

3. Note the Package Name you want to remove

🗑️ 3. Remove System Apps with ADB

#

A. Uninstall for Current User (No Root)

#

1. Make sure device is connected via ADB (adb devices)

2. Run:

   adb shell pm uninstall --user 0 <package_name>
   

   Example:

   adb shell pm uninstall --user 0 com.facebook.appmanager
   

   (App is removed for the current user but still exists in the system)

B. Permanent Removal (Rooted Devices Only)

#

1. Open ADB Shell with root access:

   adb shell
   su
   

2. Remove from system:

   mount -o rw,remount /system
   rm -rf /system/app/<app_folder_name>
   

   (Risky. For advanced users only)

⚠️ 4. Troubleshooting & Tips

#

App Returns After Reboot

#

• Some vendors (Xiaomi, Samsung) auto-restore bloatware

• Solution: Disable instead using:

  adb shell pm disable-user --user 0 <package_name>
  

Restore Deleted App

#

1. Factory Reset (wipes all data)

2. Or reinstall via ADB:

   adb shell cmd package install-existing <package_name>
