IPhone 6 not vibrating on silent?

I know right off the bat you ll ask if the "vibrate on ring/silent" is on and yes it is for both. Second I turned my ringer on all the way up when the phone is on silent so the vibration should be stronger. And when someone calls me, it does not vibrate whatsoever. I've tried tweaking the settings a lot. But IIm assuming it has something to do with iOS 9 because I've never changed my sound setting AT All or any of my settings in general before the iOS update. But now the phone doesn't vibrate. I've missed tons of important calls from parents, friends, and business. IIm glad it doesn't vibrate during something important but if IIm depending on someone to call me and I don't feel it, I could have missed something important. Such As someone can be looking for me, someone is trying to meet with me, someone is in a hurry and need me. Whatever. But I need this vibration feature to be turned on as soon as possible. Any sort of help is gladly and thankfully taken.

  • YouTube sound not working when iphone is on silent? I've had my iPhone 4 for over a year now, and I've never had this problem. It started today, if I try to watch a YouTube video without headphones and the phone is on silent, there's no audio. But if I turn the ringer on there's audio. Obviously I've looked at the volume levels, and they're up. Like i said its only started today and it's very frustrating!
