How to get a TEXT alert tone when messaging app is open

[sandman512]

So, I am currently using my wife's old iPhone 4S. When I get a text message, my phone alerts me. When I am in the open the text and reply, no problem. The issue os that after I reply and I am in the THREAD, there is NO alert if the person replies. Can I change this so I can receive an alert? Thanks!

I think you should get some sound when you get a text with the app open, but it's not the normal text sound you would get. It's a bit quieter. (I don't love this myself, and would rather have the standard text alert sound).
