Google just released the Android 11 Developer Preview! You can download it on your Pixel 2, Pixel 3, Pixel 3a, or Pixel 4.
The Android 11 Developer Preview beta will be available at some point “in the next several weeks.” This is the first build, so that mostly makes sense. It’s probably not stable enough for everyone to run yet.
If you’d like to get on Android 11, you have two choices: factory images or OTA files.
The factory image files for each phone can be found right here. At this time, Google has only posted the factory image files. For instructions on how to flash a factory image, here you go.
The OTA files for each phone can be found right here. Instructions for sideloading an OTA file can be found here.
