I turn down my ringer to 0, with no vibrate. I leave it on my desk, and when I get a message, I hear the message ding. When I check, the volume is at 2 (i mean 2 levels higher than vibrate).
This is happening several times a day. What could be causing it?
I'm using Android 6.0.1
I figured it out.
It was the "Call Blocker" app from AndroidRock.
The problem went away after I uninstalled the app. To be sure, I reinstalled it, and the problem came back. I tried this about 3 or 4 times to confirm.
