Google has rolled out the public testing for the first Android 13 beta with three more planned betas coming before the final release becomes available later this year.
The first beta comes with new permissions for more granular access to media files and improved audio routing APIs. This means apps will get three different permissions to the media they want to access: images and photos, videos, and audio files. Then these apps will only have read access to the respective media file type(s).
Other than that, there will also be some improvements to audio routing and error reporting. Google will share more details about Android 13 and more new features at the Google I/O developer conference next month.
