Welcome to Vodafone Community
I have set the sounds on my new Vodafone V8 and my parents new Vodafone N8's to something more familiar but after a time, be it hours or days it resets to the default sound. Is there any way to make them stay as we want them?
That's very odd. Are these the built-in sounds or something you've downloaded? If it's the latter, thet could be issues with them, so try a stock one. If it's already stock, try different ones, just in case that makes a difference (though I can't see why).
It's also possible that this is a resource issue, so try clearing recent apps, app caches (Settings|Storage|Phone|Clear cache) and simple restart (turn it off and then on again).
If that doesn't do it, you may need to try a factory reset - don't forget to back up your content first!
I think I've solved part of this. On my V8 I can set a ringtone via the edit contact function but to set an SMS tone to my contacts I had to do it though the Messages app once I'd sent or received a message from someone. This works fine until I deleted a contact's conversation thread, then the next time I got a text from them it had gone back to default.
Hope that helps a bit.
