Google is working with Android OEMs to expand the beta of its upcoming Android release to even more devices. The company did something similar last year as well for Android P so it’s no surprise that it’s doing the same thing for Android Q as well. Android Q isn’t due to arrive for at least a few months.
You no longer need one of Google’s own Pixel smartphones to take part in the Android beta program. Google has worked with 12 device manufacturers to bring support for Android Q beta 3 to a total of 21 smartphones.
