Thanks you for answering, so it's the way it is. Just not logical dialog format that the person messages in the conversation are at top and all my messages are at the bottom. I got paid versions of Evolve SMS, Textra SMS, and they place my messages and the person in a particular conversation the logical correct way; my message following by the person message and again my message and again his or her. Well but it seems that Samsung stock message got this all top- all bottom format. So I must let it be then. Thanks again for your answer.
