Anyone else? A solution?
As you all know in Android Setting I can choose the predefined tones fir ringer and notification. This way for every messaging app (whatsapp, gmail, email, hangouts, facebook, etc.) in the app setting, under tone settings, I can choose PREDEFINED and use the tone chisen in Android Setting. The exception to this is the Sony Messaging apo, where under tones I can chioose among none or many other tones, but no predefined ootion.
