https://us.community.samsung.com/t5/Samsung-Apps-and-Services/Blue-dot-text-message-by-contact/m-p/1287525#M22990 <P>I may be wrong, and I don't know if anyone has answered this post already, but I've noticed a trend with contacts to have the blue dot. I believe that it is to mark those that have real-time text messaging. Which is a feature that you can see when the person you are texting has received your message, and is replying or typing in real time.</P> Wed, 24 Jun 2020 09:24:41 GMT SafeCareGlass 2020-06-24T09:24:41Z
