True multitasking on a smartphone would have seemed ridiculous not long ago, but ever-growing screen sizes have made running two apps side-by-side on a smartphone more than just a novelty. Multi-window functionality started to pop up from some manufacturers in recent years, and Android Marshmallow gave us a glimpse of the feature — if you were willing to root your phone.
Nougat, though, marks the official debut for multi-window functionality on Android. Multi-Window Mode can be used in either landscape or portrait orientation: In landscape, you’re limited to a 50/50 split between the two apps, but in portrait you can also opt for a two-thirds/one-thirds division.
Switching to Multi-Window mode is quick and easy, just follow these steps to enter the world of Android multitasking.
1. Open the primary app that you would like to use.
2. Long press on the Overview button in the lower-right. You will see the standard overview button replaced with two small rectangles.
3. Select the second app you wish to use from the app switcher.Apps will display a dialog that says “App doesn’t support split screen” if they won’t work with the feature.
4. To change your secondary app, tap the double rectangle button in the lower-right and select a new app from the app switcher.
If you’re in portrait mode press on the white line in the center of the screen between the two apps and drag to switch to a two-thirds/one-thirds split.
5. To exit Multi-Window, long press the double rectangle button in the lower-right.You may also swipe up or down on the dividing line between the two apps to exit Multi-Window.
