Why is it so hard to change this phone to vibrate only? Where is the simple toggle for sound/vibration? Like the one in Touchwiz. Do not disturb doesn't seem to have a "set to vibrate only" option, does it?
Some things about Google's decisions are seriously questionable. And if there's no solution other than, press the volume down hardware key, and if it's not on the correct sound profile while you're doing that, you have to pull down the menu to get to the sliders, if that's the only way, it's downright idiotic.
I have to admit I have loved the switch on the iPhone ever since it's inception, it's just perfect to flick it to put your phone on vibrate.
