My Verizon Galaxy S4 just updated from KitKat to Lollipop. I used to be able to quickly put my phone into vibrate only or silent mode by holding the power button and tapping the appropriate screen button (it was below restart on the popup). This was really convenient when trying to unobtrusively silent the phone in a meeting. Now I have to enter my pin and then either use the volume buttons or swipe down the notification bar. This requires both hands and looking at my screen for an extended period of time (much more noticeable). Is there a way to get the mute button back onto the power shortcuts or to get the volume button to work without unlocking the screen?
