Android 16 Beta 3: In-Depth Analysis of New Screen Recording, Split-Screen Improvements, and Enhanced Security Features

Android 16 continues its steady progress as planned, with the official release of Beta 3 bringing several noteworthy new features. This article delves into some of the most anticipated highlights of Android 16 Beta 3: HDMI screen recording, split-screen optimizations, enhanced local network protection, and call-time security safeguards.

I. HDMI Screen Recording: Breaking the Screen Recording Limitations

Previously, Android screen recording was limited to the phone's own display. Android 16 Beta 3 breaks this limitation by adding a "RecordHDMIScreen" option to the screen recording interface, allowing users to directly record content from an external monitor. The recorded file format is consistent with regular phone screen recordings, but the filename includes the external display's internal ID for easy source identification.

However, this feature currently suffers from compatibility issues. Sources indicate that the "RecordHDMIScreen" option is unavailable when using third-party screen mirroring apps (like "Cast" functionality) or third-party screen recording software. Currently, only the native Android screen recording tool supports this feature; it cannot be extended to other applications. It's worth noting that Android 15, released in 2024, already supported external display screenshot functionality, also annotating the display ID in the saved image; however, neither feature is deeply integrated with Google Assistant (Gemini) or the CircletoSearch tool.

II. Split-Screen Optimization: Enhanced Efficiency and Convenience

Android 16 Beta 3 continues to optimize the split-screen experience, further refining the separation of the notification and Quick Settings panels. This update primarily improves the following areas:

• Top-Placed Media Player: Android 16 Beta 3 plans to move the media control panel to the top of the notification and Quick Settings panels, allowing users to directly control music or video playback, adjust progress, or switch songs.

• Dual-Page Switching Functionality: Future Android versions will offer two ways to switch between the notification and Quick Settings panels: swiping left or right across the screen, and clicking pill-shaped buttons located in the upper left and upper right corners.

• Quick Settings Panel Optimization: Android 16 Beta 3 implements a vertically scrolling Quick Settings panel to display more controls on a full screen. The editing interface also adds "+" and "-" buttons, simplifying the addition and removal of controls, significantly improving user efficiency.

III. Local Network Protection (LNP) Testing: Strengthening Application Permission Management

Android 16 Beta 3 introduces a testing option for Local Network Protection (LNP). In the future, apps will require specific permissions to access user local network devices, enhancing network security. Developers can enable LNP restrictions using adb commands to test app functionality and identify parts reliant on local network access, ensuring application security and compliance.

IV. Call-Time Security Protection: Countering New Scam Tactics

Google is developing a new security feature designed to prevent users from changing certain sensitive settings during calls, such as allowing apps to install other apps (sideloading) and granting accessibility permissions.

This feature is crucial for preventing scams. Scammers often instruct victims to install malicious apps after hanging up and then call back. This new feature adds an extra layer of impediment, disrupting the scammer's flow and prompting users with system warning dialogs to reconsider the caller's trustworthiness, thus reducing the risk of becoming a victim.

V. Participating in Beta Testing: Experiencing the Latest Features

For users or developers who want to try out the latest features, Google offers the option to register Pixel devices through Google's Android Beta Program and receive OTA update notifications. Users already participating in the testing program do not need to take any additional action; they simply need to wait for the update to be pushed.

Summary: Android 16 Beta 3 Feature Highlights

Android 16 Beta 3 shows significant improvements in screen recording, split-screen interaction, and system security. The HDMI screen recording feature expands the application scenarios of screen recording; the improved split-screen design enhances user efficiency; and the local network protection and call-time security safeguards enhance system security, effectively preventing potential network and phone scams. These improvements reflect Google's ongoing commitment to user experience and security, and provide new directions for the future development of the Android system. The ongoing refinement of Android 16 will bring users a smoother, safer, and more convenient mobile experience. The Beta 3 release is just one stage in the development of Android 16; more improvements and optimizations are expected in the future. We look forward to seeing what's next.
