How can you return to your call once you went ahead and slid away all your open apps, seems that when you in middle of a call and you by accident slid away the tabs for all apps in use, and the google hangouts app, but Google hangouts app still works to continue the call even after sliding the open apps away, and should you want to go back to the call screen from your previous call there's seems to be no way, all I see is the dial pad for one who wants to make a phn call, but here im already on the phone call with someone and now wanting to pull up the old call?
And tips on how to pull up the old screen of your call? Or even a way to end the call without having the end button after swiping away all your apps?
