Hey guys, thanks for the help ahead of time! Typically you have to hold the back button for however long in order to launch the apps that are compatible with multi window. I would love to change this, it takes forever. Even being able to change how long you have to hold the button to launch compatible multi window apps would be nice. You can press the recent apps button but that means you would have to have had that app open already previously. Thanks again for any responses and help. I am using a Note 4 on AT&T.
