Android 11 has been out for a while now, and though things might look pretty similar coming from Android 10, there are plenty of changes inside, from revamped privacy and security to partitioning "conversations" into their own new notification category. Now that you've had some time to play with this latest version and you've read our review, here's the Android Police changelog for Android 11.
Android 11 Developer Preview 3 has a new setting for app permissions, allowing them to be automatically revoked if you don't use the app for long enough. Disabled by default, the descriptively-named "Auto revoke permissions" setting will revoke permissions for a given app if it isn't used "for a few months."
The final release of Android 11 earlier this month brought a ton of new features and improvements, but there was bound to be a bug or two with so many changes. The new media controls make the audio-listening experience a lot nicer, but they're still in need of some polish: some apps with currently playing audio can't be controlled unless you expand the quick settings panel.
Android 11 has been stable for a bit, and while it brought many improvements to the table, there are also a few regressions. One of these is a small but significant change to the quick settings tiles. Compared to earlier versions of the OS, Android 11 only displays two rows instead of three, even when the new media player isn't in use.
Android 11 introduced a nifty new interface for controlling media playback that lives among the quick settings tiles rather than the notifications. In it, there's also a button that allows you to choose the sound output (which has actually been around since Android 10). At the moment, it's only populated by your phone's speakers and bluetooth sources, even though it seems like adding Chromecast-enabled devices would be a no-brainer. It looks like Google thought the same, but it will have to be implemented by every single media app out there.
Android 10 introduced a serious regression when it comes to setting up link handling defaults. Instead of just leaving it be with the familiar "always open in this app" prompt after tapping a link that's supported by multiple apps, Android 10 would instead throw you into settings, where you'd have to confirm that you really want links to open in that application all the time in a drop-down menu. Thankfully, this behavior is a thing of the past in Android 11, which reintroduces the familiar two-tap solution.
As the Android 11 team worked on new features and system-level changes over these past few months of the beta process, the Google emoji team was doing the same, adding 117 new entries approved by the Unicode Commission. We got an early look at the updated emoji library last month, and now these emoji are saying hello to everyone as Android 11 begins rolling out to the general public.
Now that Android 11's codebase has been released, folks have started digging through looking for smaller changes that may have gone unnoticed — or which hide future as-yet-unimplemented features. One small but potentially useful tweak has been spotted: Android 11 expands the utility of the new "firm" or "deep" press feature on the Pixel 4 and later to let you expand bundled notifications.
Android gives you separate volume control for media, notifications, and alarms, but Google appears to be working on adding a fourth slider to the mix. The AOSP Android 11 code suggests that the company is at least considering to add dedicated volume control for voice assistants, including but not limited to Google Assistant.
