OnePlus How to change notification sound

We may change the notification tone that alerts us to new SMS messages or messaging from WhatsApp, among other things, at any time if the tone is already overheard.

There is a choice of pre-installed tones on the OnePlus smartphone, which can be expanded as desired thanks to the function for using a personal notification tone.

Note: To use a custom notification tone, such as an mp3 file, simply copy it to the internal memory of the device.
The folder path does not play a major role here, as the OnePlus smartphone automatically searches all file paths and displays the results.
