Android 15 hides a treasure trove of practical tools that elevate everyday smartphone use on devices like Google Pixel, Samsung Galaxy, and other compatible handsets. These under-the-radar capabilities focus on privacy, multitasking, and performance tweaks without needing root access or complex setups. Dive into them now to customize your experience and stay ahead in mobile efficiency.

Secure Private Space Vault

Private Space acts as a concealed profile for apps needing extra protection, such as banking or dating services, keeping them out of the main app drawer and recent apps view. Setup involves a dedicated lock screen with fingerprint, face unlock, or PIN, ensuring total isolation even from notifications or settings scans. This shines on shared family devices or during travel, where quick profile switches prevent accidental exposures.​

Enable it through Settings > Security & privacy > Private Space, then choose apps to install within the vault. Developers note apps may need updates for full compatibility, but stock functionality hides data seamlessly. Pair with randomized MAC addresses on Wi-Fi for layered anonymity during public logins.​

Effortless App Pair Multitasking

Pin favorite app duos for instant split-screen activation, ideal for foldables or tablets like the Pixel Fold, saving time on routines like email-plus-calendar or browser-notes combos. Access saved pairs from the home screen or recent apps menu after initial split-screen setup via the app icon’s split option. Large screens benefit from a persistent taskbar for one-tap swaps, boosting workflow on Pixel Tablets or Galaxy Z Folds.​

This extends to cover screens on flippables, declaring app support for compact displays. Test pairs during study sessions or remote work to cut navigation by half, with predictive back gestures smoothing transitions.​

Smart Bluetooth and Wi-Fi Privacy

Bluetooth now auto-reactivates daily for Find My Device tracking, but toggle it off permanently via Settings > Connected devices > Connection preferences > Bluetooth > Automatically turn on tomorrow. This prevents unwanted reconnections in quiet zones while preserving location features.

​These privacy-focused changes in Android 15 align closely with India’s upcoming digital privacy rules, helping users gain stronger control over personal data and network exposure.

Hide your device name from Wi-Fi networks under Network & internet > Internet > gear icon next to a connection > Privacy > Send device name (off), adding randomized MAC for anti-tracking. Crucial for cafes or airports, this reduces profiling risks without slowing speeds.​

High-Quality Webcam Mode

Transform your phone into a pro webcam with HQ mode over USB, delivering sharper feeds for calls on PCs or Macs, though it may warm the device during long sessions. Connect via cable, tap the USB notification, select Webcam, then hit HQ in the corner—perfect for hybrid workers upgrading laptop cams.​

Supports biometrics for secure sessions and integrates with apps like Zoom. Test on Pixel 9 series for low-light boosts via Camera2 extensions.​

Home Controls Screensaver Hub

Dock or charge to activate a smart home dashboard screensaver, showing tiles for lights, thermostats, and live camera feeds on tablets or phones. Navigate to Settings > Display & touch > Screen saver > Home Controls (on) for instant access, turning idle time into control central.​

Ideal for Pixel Tablet owners monitoring doorbells or adjusting AC remotely. Syncs with Google Home ecosystem for voice-free tweaks.​

Adaptive Display and Vibration Tweaks

Boost visibility with Color contrast under Settings > Display & touch, dialing up elements in dark mode for easier reading on Material You themes. Adaptive vibration senses context—like pocket vs. table—fine-tuning intensity via Sound & vibration > Vibration & haptics.​

Notification cooldown ramps down repeated alerts from one app, cutting buzz fatigue. Enable richer vibrations per channel for personalized alerts.​

Theft Detection and Lockdown

AI-powered Theft Detection locks the screen if it senses a snatch or bike ride-away, triggering offline Find My alerts. Hold the power button for Lockdown Mode, blocking USB debugging and biometric bypasses during threats.

Many of Android 15’s hidden security tools directly protect users from threats discussed in 5 Major Cyber Scams Right Now & How to Stay Safe, including phishing, device theft, and unauthorized access.

Partial screen recording shares only one app, blurring sensitive fields like OTPs automatically. Apps detect recordings for added privacy layers.​

Easter Egg Space Explorer

Repeatedly tap Settings > About phone > Android version to unveil the triangular badge, then long-press for a mini-game planting flags on planets. Unlock the “Landroid” screensaver for ambient space visuals, a nod to exploration with improved graphics over prior versions.​

Performance and Battery Secrets

Dynamic Performance Framework lets games self-tune thermals and power, while app archiving shrinks storage via OS-level support. Check hardware via new Device Diagnostics, and use StorageStats for byte breakdowns by type like AOT code or libraries.

​Properly enabling these performance-focused features can resolve common lag issues, as explained in How to Fix Slow Mobile Performance on Android (2025 Guide).

Adaptive charging pauses at 80% for health, with Low Light Boost for night shots. SQLite tweaks speed databases, and 16KB page support future-proofs native apps.​

Camera and Media Enhancements

In-app Camera Controls grant precise tweaks to hardware algorithms on supported devices, with HDR headroom balancing SDR/HDR outputs. LoudnessCodec standardizes audio volume across apps, while Low Light Boost auto-exposes dim scenes.​

Virtual MIDI 2.0 links composition and synth apps seamlessly. Partial screen sharing adds MediaProjection callbacks for custom experiences.​

Advanced Developer and UX Polish

Richer widget previews generate dynamic RemoteViews, and edge-to-edge enforcement pads UI near system bars. TextView allocates space for cursive scripts, preventing clips, with locale-aware EditText heights.​

Improved Do Not Disturb rules via AutomaticZenRule customize activations. Satellite UI ensures consistent connectivity experiences.​
