I know for a fact the audio type is supported, its an mp3. I can play mp3s for an hour on a walk, shut down the player, and then try to resume playing again only to get the message "this audio format is not supported" the only things I do between when I stop playing music and try to resume playing it are texting and browsing the web. I have to restart my phone to fix the issue. 1. How can I prevent this issue? 2. Is there another way other then restarting my phone to fix the issue? Im using the default media player that came with the phone. Theres days I can stop listing to music and 5 minutes later the audio format will not be supported. Its not just one particular song this happens to but all of them.
