I have the S9 plus. I am currently using message plus I downloaded. I can set individual notifications and ringtones to different contacts. With the message app with the phone, isnt possible
This feature was removed with the oreo 8.0.0 release. Even the s7 recieved the oreo 8.0.0 update. So anything samsung running oreo can not use the text notification personal tone
Maybe I should mention I am on Sprint? Because none of tips are getting me anywhere. I have downloaded Verizon's messages plus for now, which is allowing me to set tones for conversations, but not for contacts. They're smart enough to make phones and such but not smart enough to either fix this or that they should have just it alone.
Im on sprint too and i am able to change my tones again. But if its in a group it wont work and it will change to default if u delete the text thread. While in a text thread click on the 3 dots in the upper right corner. It will say notification, click on it to change it from default to custom
