Text popup bubble

[Staceyp3]

I have a Samsung Galaxy S7 plus, running nougat 7.0 software, from AT&T. When receiving a text, my pop up is a small bubble sentence. I want the whole square box. When using a 3rd party texting app, I cannot assign times for each person. So I would like my stock and to work.

Are you saying that you would like to have the stock ROM (OS as-is from Samsung) to replace what AT&THE choose for your S7?
