So on my Galaxy s4 I know how to set up a custom sms/mms tone for individual contacts. HOWEVER they are always the same tones listed. When I create or download any notification sound it won't show up on the list when I try to make it a custom but it will show for my default list. Apparently I did it somehow because one of my notification tones I created appeared on the list but that's it. Anyone know how to add to that list?
