At present, Google has launched three Android 11 developer beta versions. According to the original plan, the company will release Android 11 Beta on June 3.
However, according to the latest news released by the official Android developers on Twitter, the June 3rd event and beta planned to be held are currently delayed and there is no schedule.
We are excited to tell you more about Android 11, but now is not the time to celebrate. We are postponing the June 3rd event and beta release. We'll be back with more on Android 11, soon.

Google is also preparing to launch the Google Pixel 4a version at the public beta release conference, so the specific release time of this product has also been postponed.
The specific reason for the delay is not yet clear, but it should be reasonable that this should not affect the release date of Android 11, usually the new version is released every August.
