Setting the melody to a contact
To set the melody for a specific contact, go to the phonebook, in the contact list, find the person you want to use to select a specific ringtone and open it to view detailed information. Click the icon of the additional menu in the upper right corner and select "Set ringtone" in the window that opens.
In some phone models to set your own music as an incoming call for a specific contact, you need to enter the contact edit mode and find the item "Ringtone setup" or "Ringtone". If there is no such item, it is most likely located in the additional menu (three dots in the upper right corner of the screen).
