I have the Droid Maxx its running 4.2.2, group messaging in settings is on. Can someone please reply with a solution for Group Messaging. Anytime I reply to a group it goes to everyone individually but I receive messages from groups fine. When I reply it seems as though it stays grouped but everyone texts me back saying its not grouped. I cant use a 3rd party messaging app that requires registering and making a username like "Whatsapp" because that's RIDICULOUS. I upgraded from an Iphone4 and group messaging is an everyday need for me. I have over 5 friends with GS4 and they have No problem with group mms. This is really upsetting....Any help is appreciated. Thank you.
