You CAN assign a ringtone to a Contact.
Here are the steps:
Go to Contacts.
Tap a Contact to open.
Tap EDIT
Open "View More" at the bottom.
Tap on Ringtone (Probably says Default Ringtone).
This will bring up the Ringtone List.
Tap on the Ringtone you want to use.
Ringtone selected will light up.
DO NOT TAP ON "ADD".
Tap on "Back arrow" to go to previous page.
Tap "SAVE"
Your selected ringtone will be assigned to that Contact.
Even the Samsung Tech Rep said that this was not possible with the current update.
My Verizon Tech Rep told me how to do this.
Please let me know how this works for you.
Have a Blessed Day.
