Uninstalling System Apps

Uninstalling System Apps
Pre-installed system apps cannot be uninstalled in the conventional way via system management or the app store.
When using the Volla Security Mode, unneeded system apps can be permanently or temporarily disabled.
However, if you absolutely want to uninstall a pre-installed system app, this is not intended and requires using the terminal.

You can install these tools via the respective package manager/app store of the operating system or, on Linux/Ubuntu, via the terminal using:

Code: Alles auswählen

sudo apt install android-tools-adb

Settings → System → Developer Options → Enable the toggle for “USB Debugging.”

Connect the phone to the PC → In the small pop-up window, allow the PC to access the phone.

On the PC, start the Command Prompt (Windows) or Terminal (Linux) and proceed as follows:
