Can't select keypad options when I make a call

[Mathsnerd57]

When I make / receive a call, the call screen disappears almost immediately, and goes to a new phone call screen. If I have to make an option on the keypad, I can't pull the active call screen back to type on the keypad. It is in miniature on the notifications, so I can hang up, but I can't get the screen to stay there so I can do the usual things you need to do on calls. Any help?

Hi @Mathsnerd57. Can you send some pics/ video of this please?

I don't know how to video my screen, sorry.
