I don't know whether this is particular to the Galaxy Nexus or a general Android issue, but it's a major frustration for me. I put the phone in vibrate mode when I'm at work or other places where sound would be rude. I put the phone in my pocket. Any accidental contact with the volume buttons while there takes it out of silent mode!
With the phone just sitting on the table I can reproduce some of this. Either volume button will wake up the phone, which seems dumb to me, but an accidental touch of the power button while in pocket would wake it up too. Hitting volume up a second time takes it out of silent mode! I have no screen lock, and maybe that would be a workaround for this issue, but I would find it inconvenient. Volume down wakes the phone, and a second volume down switches it from vibrate mode to mute. The issue with that is that I'll miss notifications if the phone doesn't even vibrate.
Do all Android phones behave this stupidly? Only the power button should wake up the phone (i.e. "turn on the power"). Volume buttons should only adjust the volume level (hence the name, duh) and should only do that when the speaker is enabled.
