Key Features and Improvements in Android 15

Partial Screen Sharing

One of the most anticipated features in Android 15 is partial screen sharing. Users can now share or record specific app windows instead of the entire screen. This functionality, initially introduced in Android 14 QPR 2 for Pixel devices, is now extended across the Android platform.

Satellite Connectivity Support

Android 15 enhances satellite connectivity support, ensuring consistent user experiences across different devices. Apps can detect satellite connections, enabling better awareness of network service availability. Additionally, SMS and preloaded RCS apps can utilize satellite connectivity for messaging, expanding beyond emergency use cases.

New In-App Camera Controls

Developers now have access to advanced camera controls, including low-light enhancements and precise flash intensity adjustments. These extensions enable better customization of camera performance, providing users with improved photo and video quality.

Universal Keyboard Vibration Toggle

A new system-wide toggle allows users to control keyboard vibration universally. This setting overrides individual keyboard app settings, providing a consistent user experience across all keyboard applications.

Sensitive Notifications

To enhance security, Android 15 introduces sensitive notifications, preventing one-time passwords (OTPs) from being read by malicious apps. This feature is particularly important for two-factor authentication (2FA), adding an extra layer of protection.

Enhanced Bluetooth Functionality

Android 15 offers a more detailed Bluetooth Quick Settings tile, allowing users to toggle connections, manage individual devices, and pair new devices through a convenient popup dialogue.

Auracast Audio Sharing

Auracast makes audio sharing via Bluetooth LE Audio streams more accessible. Users can broadcast audio to nearby devices without the need for pairing, facilitated by a new audio-sharing page in the settings menu.

High-Quality Webcam Mode

Android 15 improves the webcam feature introduced in Android 14 QPR 1. A new High-Quality (HQ) mode enhances video quality, though it increases battery consumption and heat generation.

Continuity Features for Foldables

Foldable devices benefit from enhanced continuity features, allowing users to control app behavior on front displays. Options include automatic activation for specific apps or a swipe-up-to-continue mode, ensuring a seamless transition between screens.

Better Cover Screen Support

App developers can now declare properties for apps to be displayed on small cover screens of foldable devices, improving usability and user experience on these secondary screens.

Persistent Taskbar for Large-Screen Devices

Users can now choose between a transient or permanent taskbar, offering flexibility for multitasking on large-screen devices. The taskbar can also invoke the Circle to Search feature, enhancing search capabilities.

Health Connect Updates

Health Connect by Android now supports additional data types, including skin temperature and training plans, enriching the health and fitness tracking capabilities of the platform.

Virtual MIDI 2.0 Devices

Support for MIDI 2.0 devices via USB is extended to virtual MIDI apps in Android 15. This allows composition apps to control synthesizer apps as virtual MIDI 2.0 devices.

HDR Headroom Control

Apps can control HDR headroom to balance HDR and SDR content, ensuring a consistent visual experience without overpowering brightness from HDR elements.

Loudness Control

Android 15 introduces support for the CTA-2075 loudness standard, helping developers maintain consistent audio levels and reducing the need for constant volume adjustments.

Edge-to-Edge Apps by Default

To maximize screen utilization, Android 15 forces apps to use the full height and width of the display by default, providing a more immersive user experience.

Predictive Back Gesture

The predictive back gesture feature, previously in Developer Options, is now fully integrated, offering smoother and more intuitive navigation through system animations.

App Pairs for Split-Screen Combinations

Large-screen device users can save and quickly launch their favourite split-screen app combinations, enhancing multitasking efficiency.

New Collapsible Volume Panel

The updated volume panel features thicker sliders, a persistent media output shortcut, and new animations, providing a more user-friendly interface for volume control.

Richer Widget Previews

Developers can now create personalized widget previews, offering users a more representative view of widget outputs in the widget selector.

Bluetooth Auto-On

As part of the upgraded Find My Device network, Android 15 includes a feature to automatically turn on Bluetooth, enhancing the network’s efficacy by ensuring more devices participate.

Conclusion

Android 15 represents a significant step forward in mobile operating systems, introducing a range of features and improvements that enhance user experience, device functionality, and developer capabilities. From partial screen sharing to advanced camera controls and enhanced multitasking on large screens, Android 15 is poised to deliver a superior mobile experience. Stay tuned for the official release and experience these innovations firsthand.
