Google’s latest update to its Android operating system makes your smartphone less desirable—to thieves, that is.
Android 5.1 was rolled out on Monday with a new anti-theft technology called Device Protection, according to Google’s Official Android Blog. The system will keep your stolen or lost phone locked until you sign in with your Google account, even if someone restores your phone to factory settings.
Device Protection will be available on smartphones shipped with Android 5.1, and also the Nexus 6 and Nexus 9.
Other features on Android 5.1 include support for multiple SIM cards and HD voice calling between compatible devices.
Apple introduced a similar feature on iOS 7 called Activation Lock, which police in San Francisco and New York have attributed to big drops in iPhone thefts.
