Ringer Volume

Volume level of phone ringer.

When Display is enabled, a popup will show the new level.

When Sound is enabled, a tone will sound at the new volume level.

If you want to put your phone in vibrate or silent mode, use action Audio / Silent Mode, not this.

Note: on some devices Notification and Ringer volume are linked, changing one will change the other. There may be an Android setting for controlling that behaviour.
