For a while now we have been hearing reports about some of the features of Android Q, where the folks at XDA Developers managed to get their hands on a leaked build, but unfortunately there was no mention of when the official developer preview would be launched. There was some speculation that we could be getting close, and now it seems like the time has come.
Google has officially announced the launch of the beta for Android Q. The beta will be initially available to Pixel devices which means that non-Pixel users will have to wait their turn. Note that this is only the beta which means that certain features might not work, or certain features could actually end up getting removed ahead of the final release.
