I have not been able to figure out how to select a ring tone I have imported into the phone for my messages. I have a recording of my grandson saying "text message" which I used successfully in my Samsung S2. I have just purchased a Samsung S5 Neo, I have saved the sound to my files. I was able to add it as a sound option to my list of sounds for the ringer when I get a phone call but not to the notification list for my text messages. I do not see an option there to add a sound. What am I missing.
