I recently came into possession of a Samsung Stratosphere, naturally running Android software. Recently it, much as the title indicates, is suffering from a stuck notification tone. Though I have "Ta Da" selected as my notification ringtone, it appears to be stuck on the "Stepping Stones" notification ringtone. Or at least that is all I hear whenever I receive a text message or notification. Some assistance would be gladly appreciated as I am new to the Smart Phone scene.
