Today, Google is releasing its second developer preview of the next version of Android, Android 12. Note that this isn’t considered a beta just yet; that should be coming in May. For now, all of this is focused on developers.
There are a bunch of new features though; for example, there are going to be better controls for lockscreen notification security. Developers can set notifications to require authentication before seeing them, or before taking action on them. Developers are also getting more control over app overlays, which let you show content on top of the active app.
Not a lot of major new features just yet – those will be unveiled later.
