One of the Android Nougat update’s biggest additions for tablets and large-screened phones is its new split-screen multitasking mode. Samsung has supported its own version of this feature for years, and Apple added it to newer iPads in the iOS 9 update, but official Google support for it should make it usable on just about anything that runs Nougat.

Google hasn’t changed anything about the implementation since we first took a look at the feature in the earliest Nougat beta—that article and the video above lay out the basics of what it’s capable of and what it’s like to use. Now that I’ve had some time to play with the near-final version of the feature on a Nexus 9, I can say that the biggest pain point (as long as you have a fast phone or tablet) is going to be third-party app support.

Resolution independence in iOS is just a couple of years old, which meant that there were still many apps that didn't support Split View multitasking when iOS 10 came out. But resolution independence has been baked into Android for much longer, so pretty much any app you download is going to support multitasking even if it hasn't been updated in years. The only exceptions are apps that run in full-screen mode (most games do this) or apps in which developers have explicitly disabled the enabled-by-default android:resizableActivity property.

But as with many things on Android, this is a double-edged sword. On the one hand, those lucky enough to have the Nougat update early can enjoy multitasking from day one regardless of what apps they use. On the other, few apps will be optimized for multitasking. In the best, most harmless cases, this will just mean putting up with intermittent warning messages. In other cases, you’ll find that apps don’t actually refresh themselves unless the app has focus—tap away from your messaging app to work in Word or browse in Chrome, for example, and you may stop seeing new messages until you tab back over to your messaging app. Crashes and instability were common during my testing as well.

When it’s working well, split screen multitasking on an Android tablet really does make the operating system feel more productive, just as the equivalent iOS 9 feature made iPads feel more productive. But “official” support from many apps may take time to roll out—Android apps tend to adopt new features more slowly than iOS apps, due in part to Android’s fragmented ecosystem. And while most apps work OK without any effort on their developer’s part, you’re still going to run into problems while you wait on the app ecosystem to catch up to Google.
