Is there any way to turn off phone ringer volume but keep notification volume on? When I turn ringer volume off it turns off notification volume too, which makes no sense.
You would have to go into the phone notification settings to change the ringer - change option to none. But this begs the questions, how are you going to know you have a phone call?
Welcome to Android Central! Which phone do you have? Some phones might have this feature, but not all. (It's not a native Android feature -- i.e., it's not possible on Pixel phones.)
