over the years of using smartphones i have become more and more discrete in how i use them
for example i have even stoped using the ringtone(s)
if it is in my pocket i just set it to vibrate
it i am at work or at home i just put it completely on silent as long as it is within viewing distance i can detect all my calls
if really i need sound notifications they are on minimum volume
i have since moved on from the "loud" alerts which can even be annoying to other people that i may have around
and with this approach, that i can understand is pretty much personal, i would be happy to have a very minimal call alert option on my lock screen
This is what is so great about Apple Watch...nothing beats getting silent notifications on your wrist without anyone having to hear a ding, buzz or ring. And on a few occasions, I even had to answer a call on it when my phone was in another room.
