    B. Diddy: Thanks for your reply. Shortly after I placed this I joined this group. I was messing around with my S3 and came across test modes that included an audio mode. I was given this phone from my brother. I was unable to use the phone as I have an AT&T GoPhone account. However, my brother had me place some mp3s into it. WOW! I later added the Poweramp app. I deleted the phone part, and that included the dialer. Last year I bought a SCOSCHE FMT4R so I could use the S3 on any FM radio. Are you aware of that audio test mode? Thanks!

    Sorry, I don't know about it--let's see if others who are more familiar with that phone can weigh in.
