I'm using Danvdh's Google Play Edition 07-17-2014.
When I "hang up" after a call, last used app opens.
To describe it better, this is what happens: After reading a e-mail I close the e-mail with my Home button. Later I decide to call a friend. I'm using Dialer One as my preferred dialer app. It's configured to close after call. When I "hang up" my last used app opens. In this example it will be the e-mail I read. If last app before calling was Facebook it opens Facebook.
Does anyone have a solution on this problem?
