Good news for people who like near-final previews of mobile operating systems. Android just dropped Beta 4 for Android P, marking the last preview milestone before the full version launches. That means the still unnamed OS is just around the corner — promised to arrive at some point later this summer.

As the all of the above implies, this build should be pretty close to final, including all of the systems you’ll see in the shipping version. The release is primarily focused on developers, looking to make sure their apps are up to date with Android P when it ships.

That includes a number of the new OS features, which will impact usage across apps, including multi-camera support, display cutout, enhanced notifications and ImageDecoder. More details on all of that can be found here.

Of course, the build is open to anyone who signs up for the Android Beta Program, so long as you also have access to a Pixel device to test it on — there’s a sign up form here. Those who have been testing out earlier builds should be receiving Beta 4 as an automatic update at some point in the near future.

No specific date has been given for the final build — just that it’s “coming soon.” Ditto for the name — though there’s no shortage of dessert foods starting with “P.” These days, I’m leaning toward Pop Rocks. But then, I’m kind of always leaning toward Pop Rocks. Hey, anyone know where a guy can get some Pop Rocks in 2018?

Anyway, more info here.
