My phone is ringing during calls.

[AC Question]

I'll be talking to someone in a call, when I get the loud ringing of an incoming call. I don't know if the person I'm talking to can hear it, but I hear it so loud that I can't continue the conversation.

I have a Nexus 6P, so if I swipe down from the top the ringing stops. I never see an actual incoming or missed call when this happens.

Any idea what to do?

Either the caller or yourself has Max-Volume & speakers
open. Is avoidable by switch the phone to vibration only
Also Reset to off-On the icon sound: Any better now.?
