How to enable split screen when and hold recent button on One UI ??
They got ride of that feature and went with the Google version of multi window.
Which means:
Tap on recent button
Tap on the app bubble (brings down an option menu)
Tap on either:
Open in split screen
Open on pop up
Other words they dump down the multi window features......
No more slide from corner to popup window.
No more switching the top window with the bottom window once in split screen.
Actually No more option menu when you click on the middle bar that separates the windows. It's just a middle bar that you can resize the windows only.....
Oh well you win some and you lose a lot with Samsung is updates.
