When listening to music on my phone (running Android 4.0.4 ICS), I am unable to adjust the ringer volume with the hardware volume controls. Pushing either of them adjusts the music volume and not the ringer volume.
If I hold down the power button, a menu appears that provides me with the choice of turning off the ringer completely, enabling vibrate-only mode, and restoring the ringer volume to its previous level. However, there appears to be no way to actually adjust the ringer volume level.
Am I missing something?
