[Android Central Question]

After I've been talking on the phone for a few minutes, a tune starts playing making it difficult to hear

[B. Diddy]

Welcome to Android Central! Which phone? If you take the phone away from your ear and look at the status bar, are there any notifications that seem to be associated with it? Is the tune playing from the phone's earpiece speaker (i.e., in the background of your call), or is it playing over the phone's main speaker (i.e., the one where music and other media play from)?
