All sounds and notification volumes are up, and it's not set to vibrate or anything. In fact it doesn't even vibrate on incoming calls even though it's supposed to. And there's also no sound when previewing ringtones in the sound menu...Please help
go to: settings>sound>interruptions> under calls & notifications activate "all interruptions" If it is not activated, you will receive no or limited(e.g. late nite) rings.
Press volume button, you should see a bell icon beside the volume bar that pops up. Tap on it and choose All. Let me know if that works.
