Samsung says J3 Luna (6.0.1) will not allow me to assign custom ringtone to a contact group (or individual contact). The contact info page appears to have the custom ringtone but when that contact calls the default ringtone is what is heard. "DND" also has some funny bugs in it. I tried Safe Mode and Factory Reset. No luck. I can change ringtones on the phone, but every caller apparently has to use the same ringtone. Suggestions?
