I'll have to try that. I have a similar problem, I've changed my ringtone to mp3, all good, but I can't get the notification tone to work. I've saved it in the media - notification file (It was one cut using a ringtone maker app) and when I go in to my settings and go to notification ringtones, it does appear. I click on it and then when I get a text, plays something different. I did notice that when my med minder app goes off, it'll play it then.
so it goes like this -
Text - Plays what it wants, for texts and delivery reports (same tune everytime)
to do task lite - Plays want it wants (Same tune everytime)
Med minder lite - plays the mp3 I set it to in notifications.
What is going there then? Anyone know?
