Re: how to set missed call reminder on galaxy note 4
I'm not sure what you mean. What exactly is a missed call reminder? Do you want to be reminded of the fact that you missed a call?
All missed calls are in the notification tray, so as long as you don't clear all of your notifications, it'll be there for you indefinitely to "remind" you that you missed a call.
Or are you looking for some sort of audible notification? Something that makes a sound x amount of minutes after a missed call to alert you that you missed a call?
