Unable to use the keypad when on a call

I have the galaxy s25 ultra. When I'm on phone or speaker, it will not let me use the keypad to push the selection(like 1,2 0r 3) top make the selection.

Where do I do that at?

Try clearing out the phone app cache. Touch and hold the app, the you will get an applet popup. Click on the tiny circle with an "i" in it and the phone app properties will show.
