Install If You Use Multi-Window
The Galaxy Note 5 borrows another feature from the Galaxy S7's version of Android Nougat: Improved Multi-Window. If you use Multi-Window mode on the Galaxy Note 5, and we suspect many of you do, you might want to think about installing the Note 5's Nougat update. Here's why.
There are some UI changes (it's a hybrid between Samsung and Google's Nougat) but if you can look past those you'll find some impressive features.
Multi-Window now operates at a platform level which means you can use split-screen and pop-up view with a host of applications. The options are far more limited on Galaxy Note 5's running Android 6.0.1 Marshmallow.
You can now access more applications at a time and a new pop-up window function supports up to five separate windows on screen. And with Nougat on board you can also launch the pop-up view directly from your Recent tab.
