Get ready for a special feature drop coming early next year that makes Android 12 even better on tablets and foldable devices. Try 12L today on the Android Emulator or an eligible device from our device-maker partners, and optimize for the next wave of large screen devices!

What’s in 12L?

In 12L we’ve refined the UI to make Android more beautiful and easier to use on screens larger than 600sp — across notifications, quick settings, lockscreen, overview, home screen, and more. Try your app with the UI updates!
We’ve made multitasking more powerful and intuitive. 12L includes a new taskbar on large screens that lets users drag and drop an app into split-screen mode and instantly switch apps on the fly. Make sure your apps are ready for split-screen mode!
Visual and stability improvements to compatibility mode in 12L provide a better experience for users and help all apps look better by default. Test your apps to make sure they're optimized for large screens.
