What does a red dot mean next to one of my text message
It means, they are using Samsung Messenger also. 🙃
Sometimes the dot is green and sometimes the dot is blue. I think the red dot is an indication the person you are trying to contact is traveling like in a vehicle. So that you don’t constantly distract them while there driving and alternately when that dot turns green theat they are stationary and now would be a good time to contact them to hrough messages.
What the red dot means is that the person you are trying to send the text message to has blocked your calls and text in there security settings. I tested it and this is the culprit.
