Re: S21 G5 texting problems
You can change the notification sound for each person in the Google messaging app. Go into the conversation, hit the 3 dots in top right corner, hit details, notifications and then sound
If you go into each individual conversation and hit the 3 dots in top right corner, you can do some customization there. Change notification sound and wallpaper background. But that is the only 2 options I see.
