Open Android Settings
The MG4 home screen does not provide a normal shortcut to all Android settings. This route uses the on-screen keyboard to reach them before installing an APK.
- Open an application with a text field and show the on-screen keyboard. The Amazon Music email or login field is one known route.
- Long-press the comma (
,) or@key. - Open Language settings.
- Use the settings search button and search for backup.
- Open the result. If it leads to an empty page, press Back once; this should reveal the main Android Settings panel.
- Enable Developer options only if the next installation step requires them.
This route is observed behaviour, not a guaranteed interface contract. Firmware updates may change it. Make sure you can return to the stock home screen before proceeding.
