I'm using my son's hand-me-down Samsung S5. It runs Android 6.0.1
A few days ago, a music symbol (quaver) appeared on the notification bar. When I pulled it down, there was just the music symbol with no text next to it. When I tapped on it, nothing happened and the symbol disappeared. The next day it appeared again. I did the same thing and it disappeared again. This morning it appeared again.
I've done an internet search for notification symbols but I cannot find this music symbol or what it means.
What does this music symbol mean?
The symbol is in the top left corner. It seems to be related to Android Auto. It only appears after I've used Android Auto. What I don't understand is I only ever use the maps application so why is the music symbol appearing?
