pair and connect a bluetooth headset.

stream some music.. then make or receive a phone call.

end the call. wait for it..... listen....

the earpiece on the epic will now pop randomly.

to disable this annoying behavior, toggle bluetooth.

Most common for me on DK28.

EDIT: another annoying anomaly from all this is when touching the screen, or receiving another phone call when in this 'speaker popping' state, ringtones and sounds that should come from the rear speaker now come from the phone's earpiece. toggling BT will correct this.
