Last week I update my nokia 6 to android oreo 8.1 ,
whenever I m on a call, and if any notification comes,
it doesn't mute at all, rather it can be heard while on the call and very load,
and also resolve the CAST screen bug, as I cannot find the setting for Enabling wireless display only youtube cast works fine.
please release the patch for the same.
Anyone else is also facing the issue or I am the only one with the problem,
Regarding notification sounds during calls:
Phone dialer app > Menu ... > Settings > Calling accounts:
Please check that the toggle for Alerts on call is off?
I don't do enough phone calls to determine if the toggle has to be on or off, to mute notifications during phone calls.
Even when not muted, audible notifications should be a discrete system beep during calls, not full blast. - I suggest report the issue to Google via Help and feedback in the phone dialer app menu.
Google want us to buy Chromecast dongles.
I have done the setting as mentioned by user389. Still the app notifications and message notifications especially whatsapp's is really irritating. Nokia needs to investigate this thoroughly. All because of an OTA update. The phone does tend to go bit slow too after the last update. Even calls get missed as the ringtone automatically gets muted !
