Google released the first public beta of Q on March 18 and the second beta on April 3. The software runs on any Pixel device and gives interested Android owners a chance to check out upcoming features and help Google track down issues with the prerelease software and apps.

Unless you need to use it for your job -- or have a spare Pixel you want to try it on -- running an early beta may not be the best use of your time. With Q, Google is focusing in large part on privacy, giving Android owners finer control over what data they share and creating stricter limits on the information apps can ask for. It also includes small but useful changes to its interface and controls.
