So if you push-and-hold the power button, the nice little "Phone options" menu pops up and lets me go into "Silent mode." This kills all sound save for your media apps. However, sometimes I still want the phone to vibrate for incoming calls and messages (text/voice). At the moment, enabling "Silent mode" through the quick method above, "Vibrate phone" always becomes unchecked. I can, of course, simply go through Settings > Sound & display, and while there can enable and disable "Silent mode" without having the "Vibrate phone" setting altered. But, this is not nearly as convenient. I would like to be able to quickly enable "Silent mode"
