Android 12 is already available as a developer preview, which we've extensively examined. But it's becoming increasingly clear that Google hasn't spilled all the beans yet and might be planning on some more drastic changes than visible in the currently available pre-release build, and it seems like that gut feeling is right. XDA managed to get its hand on an unreleased build of the upcoming OS and gives us an overview of many potentially upcoming features.The Android 12 version XDA leaked comes from an anonymous source and is quite a bit more unstable than the current official developer preview. It does, however, come with a few revamped features and design tweaks that we expect will trickle down into the next publicly available release.
