why is "home screen volume control" disabled?
Can't there be a hint shown why the control is disabled instead of having the user browse in forums for the reason?
Odd. I’ve been looking at it on my iPhone and there’s nothing there for Home Screen volume.
Fired up an Android tablet and there it is, as you say, in App Preferences. If I enable Show Notifications it enables the slider for Lock Screen Volume. If I enable that, volume buttons on the tablet work - even if I then disable Show Notifications.
