OK, so I set up the Do Not Disturb mode on my wife's phone, so she doesn't hear emails coming though all night long. I set the 'emergency bypass' on a couple of important contacts -- which on previous versions of iOS -- would play the text/call tones even when DND was active. However, what appears to be happening now is that the sounds will play for those contacts even if the mute switch is set to silent. Imagine our embarrassment at text sounds playing at the movie theater and having absolutely no way to silence it, even with the mute switch. I'm 90% certain this was not the behavior prior to 10.2.x, but I guess now I have a bit of doubt. Seems odd that sounds would manage to bypass the mute switch. The 'emergency bypass' mode text even refers to the Do Not Disturb mode, but not the mute switch ("Emergency Bypass allows sounds and vibrations from this person even when Do Not Disturb is on." Emphasis mine). I've tested this on two phones here, a 6S and a 6 Plus, both running the most current iOS (not a beta). Can anyone confirm this? Is emergency bypass supposed to play sounds regardless of the mute switch position or is this a glitch? If it's supposed to work this way -- how do you set the phone to mute email sounds at night but still allow important text messages from specific contacts come though???
