Samsung S7 text messages out of order. My husband's phone was doing this. Someone at Sprint figured it out. There is a little pin in the bottom right I believe when you go to each contact. Click on it to unpin it. What it seems to do is keep the original texts in the order they first came in and then they seem to add the next text at that location even though it is 10 texts down the line. Hubby is over the moon that his texts are in the proper order now!
