My WinPhone had this feature to set my phone silent at fixed hours of the night, but whitelist certain contacts for calls/texts.
I've recently switched to Android (OnePlus3) and while I'm sure this must be possible (iOS does it too IIRC) I can't see what its called or where to configure it.
Can someone tell me what these features are called on Android?
My phone is running OxygenOS 3.2.8 atop of Android 6.0.1
