The second beta version of Android 12 has already been released

A few weeks ago Google released the first beta version of what will be the next version of Android 12 and now the tests of the second beta version in which some important changes have been added related to privacy improvements, notifications and more.

Of the most important changes that were introduced in the first beta it is the new design that implements the «Material You» concept, It will be applied automatically to all platforms and interface elements, and will not require any changes from the application developers.

As well as a significant performance optimization with which the load on the CPU of the main system services decreased by 22%, which in turn led to an increase in battery life by 15%. By reducing lock contention, reducing latency, and optimizing I / O, you improve performance of transitions from one application to another and shorten application startup time.

And also performance improvements for database queries by using inline optimizations in the CursorWindow operation. For small amounts of data, CursorWindow is 36% faster, and for sets with more than 1000 rows, the acceleration can be up to 49 times.

Today we released the second Beta version of Android 12 for you to try. Beta 2 adds new privacy features like the Privacy Panel and continues our work of refining the version.

End-to-end, there's a lot for developers in Android 12, from the redesigned user interface and app widgets, to rich haptics, improved image and video quality, privacy features like approximate location, and much more. 

Of the most important changes that are presented in this second beta version it is mentioned that Privacy Panel interface has been implemented with overview of all permission settings, which makes it possible to understand what data an application user has access to. The interface also includes a timeline that displays the application's access history to the microphone, camera, and location data. For each application, you can view the details and reasons for accessing confidential data.

Microphone and camera activity indicators added to the panel, which appear when the application is accessing the camera or microphone. Clicking on the indicators brings up a dialog with settings, allowing you to determine which application is working with the camera or microphone and, if necessary, revoke the permissions, plus switches were added to the quick settings pop-up block with which the microphone and camera can be forcibly switched off. After turning it off, attempts to access the camera and microphone will result in a notification and an empty data transfer to the app.

Another important change is one new notification displayed at the bottom of the screen every time the app tries to read the clipboard content by calling the getPrimaryClip () function. If the clipboard content is copied to the same application it was added to, no notification is displayed.

Also the interface to manage network connections has been modernized in the quick settings block, the panel and the system configurator. A new Internet dashboard has been added that allows you to quickly switch between different providers and diagnose problems. In the list of new features added above, you can find fixes from the first beta version and issues prior to the Android 12 developer study (developer preview).

    very good, and wouldn't it be more coherent to report progress on really free projects like phosh for example?

    this reporting on android seems a bit ... offtopic
