Why doesn't the text go to the bottom on my Samsung Instinct?

Question

Whenever you get a text, it groups them according to who they're from. Every text goes to the bottom, so you can read a conversation.

Person: blah blah

Me: blah blah

Person: blah blah

Me: blah blah

But sometimes, certain texts will stay at the bottom, and the order of them will get all messed up. Does anyone know why this is? Sorry I know it's confusing.

Answer 1

You go into options and arrange them according to their date
