I have a confession... The 6+ is my first iPhone. I've had mbp, ipods, etc. but I finally got rid of my dumb phone for a smart phone with the release of the 6+. So, I'm not sure if this is a bug or how it is suppose to work, but I've noticed when I turn on DND, I don't get notifications while in other apps. Specifically, text messages. Is that normal use? When you turn on DND you do not get a notification at the top of the screen (i.e. when someone sends you a text message) while using other apps?
