Button "Return to CallUI"

[Thunichgud]

During an phone talk it is possible to change from the active CallUI to DWP - for example when I want to look for an other phone number or an address in my contacts. But after that, there is no way back to the still in the background active CallUI. So it isn't possible to quit the phone talk.
There should be a button in DWP during an active phone talk "Return to CallUI". This could be the previous green dial button from DWP, which than should be red. Or this red button quits the phone talk directly. But a return button to the CallUI would be better because there are other options to use.

I know. This works.

I don't understand this. How can I return to the CallUI ?

During a call, the "system status bar" will display the prompt message. Click it can return to the call screen.
