Android security: How to activate anti-theft features

Android devices have evolved significantly over the last fifteen years, moving from basic PIN protections to advanced anti-theft systems that include biometric recognition and device localization. To ensure maximum security, users must manually activate specific settings within the operating system to prevent thieves from accessing sensitive data, banking apps, or personal messages.

Modern security features can detect suspicious activity, such as sudden movement indicators or the removal of a SIM card, and trigger an immediate screen lock. For Samsung users, these settings are located under Security and Privacy, then Loss Protection. For Pixel users, the path is Security and Privacy, then Device Unlock, then Anti-theft Protection. Activating biometric data and a strong screen lock password is essential for these features to function effectively. Additionally, users can perform a remote lock by visiting android.com/lock.
