Here are some specific contents of this Android Q update:

Google continues to improve navigation gestures this year, gradually removing the navigation bar and supporting full-screen gestures to gain some extra screen space. Swipe up from the bottom to return to the home interface, swipe up and pause to display recent apps, and return by swiping from the left or right edge of the screen.

The Live Caption feature, driven by machine learning, provides real-time subtitles for media. The Live Caption feature works with any media that plays audio, including videos, podcasts, and audio messages. Once speech is detected, subtitles will be automatically generated, even without an internet connection.

Another feature driven by on-device machine learning is Smart Reply, which will work seamlessly across all messaging apps in Android Q, providing helpful suggestions for replies, as well as quick actions that users can take simply by tapping on a message in the Notification Center.

The dark theme that has been exposed before is finally here. It will automatically switch to the dark theme when the power saving function is turned on, or it can be turned on manually. The dark theme will not only change the system UI to black, but also directly enable the dark theme of applications that support it. In addition, developers can use the new Force Dark feature to let Android automatically create a black version of the existing theme of the application.

What users may be new to is the Focus Mode feature, which Google says will also be available on Android 9 Pie devices. This feature can be used when users want to focus on getting work done without being distracted by notifications. First you need to select the distracting apps, and then they will be disabled after activating Focus Mode.

The Family Link parental controls will be included in the settings of every device with Digital Wellbeing starting with Android Q. When you set up a device for a child, Family Link will connect it to your account and let you review apps. Parents can set time limits for specific apps and set bedtimes.

Security was a big theme at the conference. Google says Android Q includes nearly 50 new features focused on security and privacy, the latter of which even gets a top spot in Settings. There are tools to increase transparency around location, since this information is private. So if you're not actively using an app that's requesting your location, you'll get a location usage reminder. When granting location permissions, you get granular control, with three options: allow access all the time, access only while using the app, or deny location access.

Project Mainline is a feature that allows some internal components of the operating system to be updated in the background through Google Play, without requiring a restart of the phone or a full system update from the phone manufacturer.

Google says there are now more than 2.5 billion active devices around the world using the Android operating system.
