Hello. I have a Samsung Note 5 on the Tmobile network. I noticed when I open certain contacts, next to the number it shows a phone icon, video icon, and envelope icon (messaging). Some contacts has a green envelope icon while others have an orange one. How can I change them all to orange? It seems the orange envelopes sends a message as text while green ones are sent as chat. The reason I ask is because I'm using Android Auto and every contact that has a green icon won't display the message notification on my car stereo while the orange envelope icons do. I had a few contacts that somehow changed from Orange to green and I've been going crazy on how to change it back. Can someone help me, please. Thank you.
