In an effort to make it harder for criminals to target smart devices, Google has deployed an expanded set of Android anti-theft features. The updates build on measures including Theft Detection Lock and Offline Device Lock introduced in 2024. Users of devices running Android 16 or higher now have more control over a Failed Authentication Lock feature, which automatically locks a device after several failed login attempts. For new Android devices activated in Brazil, two of Android’s key theft protection features are now enabled by default. The Theft Protection Lock uses on-device AI to sense motion during snatch and grab attempts and Remote Lock is to be on automatically and accessible from a web browser.
