Following two Developer Previews, released in February and March, respectively, today Google has made the first Android 13 beta build available for public testing. If you're interested in trying out the Android 13 Beta 1, and have a supported Google Pixel smartphone, then you can just head on over to the Android Beta Program website here and enroll your device. Then you should receive Android 13 Beta 1 as an over-the-air software update within a few minutes (up to a few hours). Android 13 Beta 1 comes with new permissions for more granular access to media files and improved audio routing APIs. When developers' apps will target Android 13, they will have to migrate to this new permissions model.
