Snatch-and-Run Stopped: Android’s New AI Locks Stolen Phones Instantly

Google’s Android Security Team announced multi-layered anti-theft updates: default-on Theft Detection Lock and Remote Lock (initially in high-risk regions like Brazil) use on-device AI to auto-lock during snatch-and-run events and add an optional security challenge via android.com/lock; Android 16+ extends Identity Check to all apps using the Biometric Prompt to protect sensitive apps even if a PIN is known; Screen Lock Guessing increases lockout timing while ignoring identical repeated mistakes; and enhanced recovery tools roll out broadly to Android 10+, aiming to protect user data before, during, and after device theft.
