Android security features and AI-driven theft protection

Modern Android devices feature several built-in security mechanisms that reduce the necessity for third-party antivirus software for most users. Google Play Protect serves as a primary defense, having blocked 27 million malicious applications in the Play Store during 2025. The system utilizes sandboxing to isolate applications and manages permissions to control access to sensitive data.

Recent updates have introduced AI-driven features to combat physical theft. The Theft Detection Lock uses motion sensors and artificial intelligence to recognize when a phone is snatched from a user's hand, instantly locking the screen. Additionally, the Offline Device Lock can secure a device even if a thief removes the SIM card or enables airplane mode. Users can also utilize Remote Lock via a web browser to secure a device using only their phone number.
