I have a Nexus 5 running Android 4.3.2. I want to turn off all sound and vibration notifications for all apps, while allowing phone calls to trigger sound and/or vibrations. Is there a way to do this?
I have tried following the advice at How can I turn off Notification Sounds and leave phone sounds on but the answers don't work. There's no separate slider for notifications, and the AudioManager app doesn't shut off vibrations. I have tried the official Google answer but there's no setting, Vibrate -> Never, and setting notifications to silent does not stop the vibrations. I've tried the individual app settings, too, but there's no setting for vibration in the official twitter app, for example.
I can stop specific apps from sending any notifications at all, but that's not what I want. I want the notifications to show up in the drop-down, I just don't want any sounds or vibrations.
