Calls: Icon for hiding the dialpad in a call is confusing
In the main call display, the icon to reveal the dial pad is a dial pad. In the dialpad overlay, the icon to hide the dial pad is.. a keyboard? Doesn't make sense. When I first saw it I was like "is this going to open the on-screen keyboard? why is that here?"
Perhaps instead, the button could be a toggle button with the same dial pad icon as in the main call display and in the active (pressed in) state? To me, this would imply that clicking on it will deactivate the dial pad. Or maybe just a normal button with a down arrow?
This is discussed here:
