Hidden Features You Should Try
1. Private Space for Sensitive Apps and Data
Now, Android 15 introduces a long-awaited “Private Space” mode. This creates a completely separate, password-protected area for sensitive apps, personal files, and documents—hidden from recents, notifications, and even device settings. Apps in Private Space are newly installed and don’t interact with the main space, making it excellent for privacy-conscious users or those sharing their device.developer.android+3
How to use:

Notification Cooldown & Adaptive Vibration
On supported devices, Notification Cooldown automatically reduces notification volume for repeated alerts from a single app, helping reduce noise and distraction. Adaptive vibration adjusts the buzz strength based on whether your phone is in your pocket or on a table, balancing awareness and comfort.techadvisory

Edge-to-Edge Display Enforcement

Lockscreen Widgets Return & Enhanced Customization

Screen Recording & Sensitive Content Detection
