Travel back in time with me, if you will, to a time before Lollipop. Let’s go back to KitKat (and older!), because that’s sort of where this story starts. Back in those days, silencing your phone was pretty easy: you could just turn the volume all the way down to access vibrate-only and silent modes. It was a simple time, when moms would make homemade ice cream and kids would play in down by the creek until well past dark. We didn’t have to think about things like “how long will I need my phone to be silent?,” because everything was confined to that one simple volume slider.
