Google today announced that it is extending the preview period of Android 11 by about a month. So instead of launching a beta this month, as it had previously planned, it’ll release a fourth developer preview today instead. The first beta will officially launch on June 3, during an Android-centric online event it’ll hold in lieu of its I/O developer conference.

“When we started planning Android 11, we didn’t expect the kinds of changes that would find their way to all of us, across nearly every region in the world,” Google’s Android team writes today. “These have challenged us to stay flexible and find new ways to work together, especially with our developer community. To help us meet those challenges we’re announcing an update to our release timeline.”
