How can I change the ringtone?

【For users of Android 12 and later】

You can set ringtones stored in the device.
Background and foreground ringtones are played according to the OS notification settings.
The ringtone name appears as “System Settings” and tapping it brings up the Android notification settings screen.
Please change the ringtone from the Android notification settings screen.
If you have changed the ringtone on the Android notification settings screen, you cannot revert to the app's own ringtone (to revert, you must reinstall the app).
If the app is updated to version 1.9.5 or later on Android 12 and later, the app notification sound set at that time will be inherited.
If newly installed on Android 12 and later, “Ringtone 05” will be the default setting.
