In the recent apps screen, long-press the icon at the top of one of your apps, then select Open in Split Screen, then choose the second app.

Give these steps a try: 

1. From a Home screen, tap the Recent apps icon  (bottom-left).
2. Scroll left or right to locate the preferred app then tap the app icon (e.g., calendar, gallery, email) located at the top of the panel. 
3. Tap Open in split screen view.
4. From the Recent apps screen tap the second application to be viewed. 
    When on, tap the Recent apps icon (lower-left) to change the current app.

Even easier -- for some reason I was thinking a long press was required in your step 3 when I originally responded. Thanks for clarifying.

Can you give more details on how to return the old feature for multiple screens? It was working fine. Don't know why Samsung changed it

Sometimes after holding the app icon from the resent apps these two options disappear and i only have app info and lock app ?

With the updated goodlock in the galaxy store, there is a plugin that brings back all the old, extra split screen features with some new ones as well.
