OnePlus, Motorola, Nothing, and other manufacturers progressively rolled out updates through late 2024 and into 2025.
Most devices have now received or are actively receiving Android 15 updates as of November 2025.
Major Android 15 Features and Improvements
Privacy and Security Enhancements
Private Space – Apple’s Secure Folder Comes to Android
Private Space represents Android 15’s most significant privacy feature, introducing native protected app containment natively across all Android devices, not just Samsung phones.
How It Works:
Private Space creates a separate, encrypted area on your device accessible only through biometric authentication (fingerprint, face recognition) or a PIN/pattern. Within Private Space exists its own independent Google Play Store instance, allowing installation of apps you want kept private from other users. Apps installed in Private Space remain invisible in your main launcher, recents view, notifications, and system settings.
Perfect For: Users sharing devices with family members, employers, or others, who want to maintain absolute privacy over specific applications.
How to Set Up:
-
Open Settings > Security & Privacy
-
Select Private Space
-
Tap Create Private Space
-
Choose authentication method (fingerprint, face, PIN, or pattern)
-
Select which apps to move into Private Space
Theft Detection Lock – AI-Powered Anti-Theft Protection
Android 15 introduces intelligent theft detection using artificial intelligence and motion sensors.
How It Works:
When your phone detects sudden, uncontrolled movement patterns consistent with being grabbed from your hand (sudden acceleration and direction changes), Android 15 automatically locks your device. The system uses built-in accelerometers and gyroscopes to distinguish between normal phone movement and theft-like scenarios.
Once the Theft Detection Lock activates, your phone becomes inaccessible without your unlock credentials (PIN, pattern, biometric), protecting your data immediately.
Benefits: Thieves gain immediate access to a locked device rather than functioning hardware, dramatically reducing theft value and protecting your personal information.
Lockdown Mode – Enhanced Security for Emergencies
Lockdown Mode disables most wireless connectivity and biometric authentication, forcing PIN/password-only access.
When to Use: During emergencies, travel to high-risk areas, or when you suspect device compromise.
Activation: Hold power button and tap Lockdown from the power menu.
Privacy Sandbox on Android
Android 15 integrates Privacy Sandbox, reducing cross-app tracking while enabling privacy-respecting advertising.
How It Works:
Rather than sending your personal data to advertisers, Privacy Sandbox uses on-device processing to provide relevant ads without exposing your identity. Advertisers can target interests without accessing individual behavioral data.
Result: More privacy for users, more relevant ads for advertisers, achieved through technical innovation rather than data exposure.
Sensitive Notifications Protection
Android 15 prevents third-party apps from reading sensitive notifications, particularly one-time passwords (OTPs) for two-factor authentication.
Protection Mechanism:
Sensitive notifications—OTPs, authentication codes, payment confirmations—cannot be accessed by other applications. This prevents malicious apps from intercepting authentication codes, protecting your accounts even if you’ve installed compromised applications.
Benefit: Two-factor authentication becomes genuinely secure rather than potentially compromised by malware.
Enhanced App Screen Sharing
Rather than sharing your entire screen, Android 15 enables partial screen sharing.
Use Cases:
During video calls, presentations, or screen recordings, share only specific application windows while keeping other content private. You can share YouTube while keeping notifications, messages, and other sensitive information hidden.
Implementation: Apps like Google Meet, Discord, and Zoom will support partial screen sharing in updated versions.
In-App Camera Controls
Android 15 provides developers with granular camera control through new APIs.
Features:
Developers can now control flash strength precisely, adjust exposure levels individually, and manage other camera parameters previously unavailable. This enables third-party apps like Instagram and TikTok to offer professional-quality camera controls.
Benefit: Third-party apps can now rival native camera apps in quality and features.
Improved Multi-Language Support
Automatic language switching refinements allow more intelligent handling of bilingual or multilingual conversations.
Enhancement:
Rather than constantly switching between languages during audio detection, Android 15’s improved system recognizes when language switching is appropriate versus unnecessary. This reduces jarring transitions and improves voice command accuracy for multilingual users.
Ultra HDR Photography
Google’s Ultra HDR photography format expands to more Android devices, enabling enhanced dynamic range in photos.
What It Means:
Photos capture significantly more detail in both bright skies and dark shadows, with artificial intelligence processing creating images rivaling professional photography equipment.
Availability: Available on supported Pixel devices and increasingly on other manufacturer flagships.
User Interface and Experience Improvements
Collapsible Volume Panel
The volume control interface redesigns from a traditional volume bar to an elegant pill-shaped slider.
Benefits:
-
More intuitive swiping for precise volume adjustment
-
Visual clarity with clearer minimum/maximum volume endpoints
-
Reduced screen real estate usage compared to older interfaces
Predictive Back Gesture
System animations smoothly anticipate navigation back gestures, providing visual feedback before completing the action.
Result: Navigation feels smoother and more responsive, with less chance of accidental back navigations.
Edge-to-Edge Apps by Default
Apps now extend fully from edge to edge of your screen rather than leaving traditional borders.
Effect: Maximizes usable screen space while providing more immersive visual experiences.
Richer Widget Previews
Android 15 generates dynamic widget previews using generative AI.
Benefit: When browsing available widgets, you see realistic previews of how widgets will appear on your home screen rather than generic placeholders.
App Pairs – Saved Split-Screen Combinations
Save your favorite split-screen app combinations for instant launching.
Example: If you frequently use YouTube and Chrome together, save this pair so one tap launches both apps in split-screen mode.
Activation: Open two apps in split-screen, tap the divider, and select Save as pair.
Foldable Device Improvements
Better Cover Screen Support
Foldable phones receive enhanced support for meaningful cover screen (front screen on closed phones) usage.
Improvements: Apps now better utilize narrow, tall cover screens, enabling practical usage without fully opening the device.
Persistent Taskbar
Large-screen and foldable devices now show a persistent taskbar enabling consistent navigation.
Benefit: Navigation remains consistent across different screen orientations and viewing modes.
Circle to Search on Persistent Taskbar
Google’s Circle to Search feature works directly from the persistent taskbar on foldables and large-screen devices.
Health and Wellness Features
Expanded Health Connect
Health Connect receives updates supporting new data types including skin temperature and training plans.
Integration: All health-related data—fitness, nutrition, medical information, wellness metrics—centralizes in one secure location.
Privacy: Data remains on your device; Health Connect doesn’t share information with Google or other companies without explicit permission.
Developer and Technical Improvements
Virtual MIDI 2.0 Support
Android 15 adds Virtual MIDI 2.0 support enabling musicians and producers to use professional audio equipment with Android devices.
Result: Music production on Android becomes more viable for professional musicians.
Android Dynamic Performance Framework Updates
Enhanced ADPF APIs allow games and performance-intensive apps to interact more directly with device power and thermal management systems.
Effect: Better performance optimization, improved battery life for intensive apps, and reduced thermal throttling.
Screen Recording Detection
Apps can now detect when they’re being recorded, useful for security-conscious applications preventing unauthorized screen recording.
Smaller Quality of Life Improvements
Bluetooth Popup Dialog: Tapping the Bluetooth quick settings tile opens a popup for easier device pairing and management.
Bluetooth Auto-On: Bluetooth automatically re-enables after device restart if previously enabled.
Adaptive Vibration: Vibration intensity adapts to environmental conditions and device activity.
Keyboard Vibration Control: Universal toggle controls keyboard vibration across all apps.
