How to use ...

[beker]

... a *.m4a audio file as message notification on my S10? Do I have to convert it to another format?

 

[Ecm]

No conversion necessary. Just use it as is.

But where I can set it? I only find the settings to use it as ringtone.

Create a folder on your Internal storage called Notifications and put the file in there. Then it should be visible when you select your notification sound.
