On Wednesday, Google released a preview of the next version of Android, codenamed "Android Q." The final release should happen sometime toward the end of the year, but for now we get a work-in-progress build that will get several new versions throughout the year. The highlights for this release include new privacy and security controls, support for foldables, a share menu that actually works, faster app startup, and more.

This first release only works with Google's Pixel devices, including the Pixel 1, which is technically beyond its support window. Wider device compatibility for some non-Google devices should arrive with the second release.
