I have assigned 3 contacts with unique ringtones. How do I set ALL my remaining calls to answer with vibrate except for the contacts with the unique ringtones. I was able to do this with my enV3 but haven't found a way with my new smartphone.
By "answer with vibrate" do you mean, no sound plays when the rest of your contacts call? I couldn't find a setting, but you could always record a new sound and just cover the microphone for a few seconds, and then set that as your ringtone.
