How to change the dial pad I see when on a call


Android Expert
When I am on a call, I see this dial pad:

I hate this dial pad because it is too high on the screen. When I try to use it, my hand often triggers the proximity sensor and causes the screen to blank out on me.

Is there any way to use a custom dial pad to replace this? I have tried custom diallers, but they only replace the dial pad you see when not on a call.
