I figured out why it is happening, in MY case. I have an S5, my wife has a Nokia with windows 8.
I noticed that SOMETIMES I get doubles, not always. But the doubles are not EXACT doubles, always seemed a format difference.
Finally I discovered that any time the nokia sent messages with a line feed in it, I got dupes. the first message had all line feeds stripped, and the second was as sent.
So at this point the only way I can stop it is to ask my wife not to use line feeds.
S5 to Nokia is OK.
Nokia to blackberry is OK.
I am using verizon messaging plus.
