Remove App Bloatware without ROOT to free up memory for your phone

By default, when you buy a new phone, it will have a lot of advertising apps (also known as App Bloatware) pre-installed. You may not feel uncomfortable at first. But when the memory is full or because you want the phone screen to look neater, you will think about deleting junk applications.

You can uninstall it, but some apps can't because it's assigned as a system app. You can just turn it off/on and this seems pointless as it won't help you reclaim free memory.

So today I share with you how to remove App Bloatware without ROOT. Just enable ADB debugging and a USB cable to connect to the computer.

How to delete system apps with ADB command

Step 1: Enable ADB mode

• Access Developer options mode. If the option is not open, you need to find the phone information → Go to the tab with the same or similar name "Build number" and press repeatedly until the message "You are already Developers".
• In Developer options mode you will find "USB debugging" or "ADB debugging" option and you need to enable it.

Step 2: Connect your phone to ADB via USB cable

• Remember to set it to file transfer (MTP) mode. And make sure you have ADB installed on your computer (This you can search google).
• Go to ADB folder, hold Shift + chuột phải → select "Open command / PowerShell window here".
• Type adb devices and press Enter.
• If it is your first time connecting, a message will appear on your phone asking you to allow the connection to the computer.
• Run the command again adb devices and press Enter you'll see a message like the one shown with your device's serial number.

Step 3: Find the names of the apps to delete

• Import adb shell and press Enter.
• Then use the following command to list the apps that exist on the phone:
  • pm list packages: list the entire app.
  • pm list packages | grep 'tên-app': list the apps named in parentheses. You can fill in part eg 'goo' instead of 'google', 'ube' instead of 'youtube'.

Step 4: Remove App Bloatware

Type this command to delete pm uninstall -k --user 0 Tên-App-Cần-Xóa

Restore Deleted App Bloatware

You can easily restore previously uninstalled apps as long as you remember the name of the app.

• Import adb shell and press Enter.
• pm install-existing Tên-App-Cần-Khôi-Phục

Note: only App Bloatware that is a system app can be restored by this method. For example, Google's default apps.
