Bug description

• Start outbound call in earpiece mode (no bluetooth or wired headset, no speaker mode).
• When phone is held against my face, the proximity sensor correctly turns the screen off.
• However, while the screen is off, the volume buttons have no effect on earpiece volume.
• With the phone away from my face, screen turns on, and now I can make earpiece volume changes with the volume buttons.
