Hello, I have an older Galaxy A3 smart phone. I used to use the preinstalled S Voice app to make phone calls and play MY music in my car. S Voice has now stopped working (it has been withdrawn I believe). I have tried Google Assistant, but when I ask it to play one of my playlists...it takes me to You Tube. I want to play my music (music that I have downloaded to my phone). Is there a simple app out there that will do this please ?
