I just switched from the nokia lumia 900 to the galaxy s4 today, and i love it... with the the exception of 1 annoying thing... my group text messages are not working properly. I'm in a group text with myself and 4 other people (2 iphone and 2 s4). everyone else's keep the txts in the 1 group thread, however, i get txts meant for the group as a txt just from the 1 person to me. and it only happens with the 2 s4 phones. group text is checked in the settings. does anyone have a fix for this?
