The final beta version of Android 11 has been released by Google. If you wanted to install the beta on a Pixel 2 series through Pixel 4 series model, now would be the time since the next update, which could drop on September 8th, will be the final version. Outside of some small bugs and last-minute changes made by developers, today’s release pretty much covers what you’ll see with the final build.

You then need to click on the box titled “View your eligible devices.” Tap on opt-in and you’ll shortly receive notification of a software update. Download and install it to run Android 11 beta 3.
