One of my friends sent out a group text message to me and a few other guys the other day, but instead of showing up as one text message thread with multiple people, I received each response independently with a (no subject) title. When I responded to any of the messages, it only went to that individual, not the group. I figured this was some iMessage voodoo at first, but then had another friend who owns an Atrix 2 send a similar group text with the same outcome. I am on a rooted LTE Gnex using stock messaging app. Why won't my group text messages register / send properly?
