When I had my A51 I had my husband/daughter/&son's phone & text (using Textra) notification sounds set to the Ohio State Fight Song (they are all alumni) - everyone else's is okay to be one of the preprogrammed notification options on the phone. I figured out to add the song as their ringtones. But I am having difficulty being able to figure out how to put the OSU Fight Song into the text sound options menu... It is a free download on The Ohio State University athletic department's website. It is available to be downloaded in 3 forms.
I would like to set it up as I have been accustomed to knowing if that song rings, it is one of the 3 and I answer it faster than when I get texts from other people.
