So I am a longtime iPhone user who is tired of the small screen and limited customizability. My iPhone 4S is due for an upgrade in May and I would really like to get the Galaxy S5. The only reservation I have is the seemingly limited support for group messaging on Galaxy phones. Can anyone confirm that group messaging works, particularly with iPhone users, on Sprint Galaxy devices? Also, do you guys think that the S5 will be a worthwhile upgrade from an iPhone 4s?
