Right on schedule, Google today announced the first developer release of Android 13. These very early releases, which are only meant for developers and aren’t available through over-the-air updates, typically don’t include too many user-facing changes. That’s true this time as well, but even in this early release, the company is already showing off a few changes that will impact how you’ll use your Android phone.

Unlike with Android 12, Google plans to have two developer releases and then launch a beta in April, a month earlier than in 2021. The final release could come as early as August, based on Google’s roadmap, whereas Android 12 launched in early October.
