Love my PXL3 but the vibration is super quiet. If it's on my desk right next to me ... I don't hear or feel it vibrating. I guess this is good because the phone is not distruptive during meetings yet I definitely feel it in my pants or suit pocket. My colleagues ... Most iPhone users ... Call it the Executive Vibration. I say all of that to see if anyone has missed calls because of the "Executive Vibration" or am I simply to distracted at work?
