We can set the notification tone individually for each app installed on the OnePlus smartphone.

In addition to the pre-installed ringing or notification tones, you can also define your own tone, for example as an mp3 file.

This function is recommended, for example, to differentiate between the various messaging apps, such as WhatsApp or Facebook Messenger.
