The scenario is I'm in the middle of a phone call, apparently my face brushed the button for "add a call". I'm still in my call, looking at that "Add a call / Contacts" menu.
I need to get back to the menus that let me switch between keypad and speakerphone controls. There is no exit/X/back out button on this screen. The only screen features are "Groups" and "+" (to add a contact) then it's a list of my contacts. Dragging down from the top does nothing. Going home and selecting phone app again simply brings me back here.
If I navigate the buttons on the bottom, I can get to a "Keypad", but this keypad does not have the button to let me switch to the menu with "speakerphone on/off". Further, typing in this keypad Does NOT generate DTMF touch-tones to the recipient, and so it cannot control navigational menus.
How do I abort an "Add a call"?
