Google rolled out a new Google Play Services update for Android this week, introducing all kinds of new features and improvements for developers. But it’s not all good news. The company has also quietly disabled Android Device Manager, the feature that allows users to remotely lock and wipe lost and stolen Android devices.

Android Device Manager, a new tool that was released just last month that makes it easy to track your Android-powered devices when they go missing, can now remotely lock them, too. The new feature, added today, means you can secure the precious data on your device and prevent it from ending up in the wrong hands.

Google has patched a major security vulnerability in the Android platform that allowed hackers to inject malicious code into trusted applications without changing their verification signature.

Researchers have uncovered a major security flaw in the Android operating system that allows hackers to modify trusted apps without changing their verification signature. Attackers could take advantage of the vulnerability to install keyloggers, backdoors, and other malicious functions into apps, which would continue to look completely legitimate to their users.

BlackBerry has today launched its Secure Work Space service for Android and iOS, allowing enterprises to manage their fleet of devices through the BlackBerry Enterprise Service 10 administration console — regardless of the platform they’re running.
