mp3 for ringtone forbidden?

[Pflichtfeld]

When I choose "ringtone for all shown contacts" and try to choose an mp3, it tells me: wrong type of file.
So: Is it not possible, to choose a mp3 for general ringtone?

Hello
Do you use the ringtone selector provided by the system?

Some devices have restrictions on file types for general ringtones. Check your device's specifications or use a file converter to change the format if needed.
