The fresh assembly contains a lot of innovations. For example, it has improved security controls for notifications on the lock screen. Developers can customize notifications to require authentication or some other action to view them. In the fresh assembly, there is also more opportunity for displaying content over windows of active applications.

Android 12 DP 2 also boasts a host of new UI tools, such as support for rounded screen corners. Since many modern smartphones have rounded display corners, Google has introduced new APIs that allow you to request information about the shape of the corners so that the application can compensate for them.

The new build also brings improved Picture-in-Picture mode and new APIs that expand the interaction with related devices such as smartwatches and fitness trackers. A new build of Android 12 is available for developers using Google Pixel 3 or newer smartphones.
