How to use split-screen mode in Android Nougat

At long last, you can ramp up your productivity by looking at two apps at the same time.

At long last, Android has native support for split-screen mode.
It’s a feature that’s long long been enjoyed by those who use high-end Samsung Galaxy smartphones and tablets. Google’s implementation in Nougat stands on Samsung’s shoulders, offering an easy-to-use and flexible mode for doing two things at once.
Our examples come from a Nexus device, so you’ll just need to pay attention if your navigation buttons are on your device’s bezel.

Go split-screen

To launch split-screen mode, you need to have one app open. Then, touch and hold the Intents button. You may know it as the “recent apps” button. Notice that it changes to a different icon to indicate you’re in split screen mode.

Half of the screen will feature the app you’re using, while the other will show a list of previously-used apps. The scrollable card deck is the same as you’d see during any typical multitasking session.
You’ll see a small pop-up notice over the card of any apps that don’t support split-screen view. If you want to use one of the apps in this list that supports the feature just scroll, tap it, and then you’re good to go.

To go back to just one app, touch and hold the Intents button. You’ll see the top app (or the one on the left if you’re in landscape mode) fill the screen.
However, let’s say one of the apps you want to go split-screen with isn’t in your multitasking list. Touch the home button and you’ll be taken to your home screen.

Once you find the app that you want to use, tap on it and then you’ll be back in split-screen mode. 

Touch and hold the slider in the middle of the screen, and you can use it to increase or decrease the the amount of screen real estate dedicated to that particular app.

To end your split-screen session, touch and hold the Intents button and the screen will go back to your original app.
