An anonymous reader writes: Google has officially announced Android Lollipop 5.1. This is a small update to the mobile operating system, and focuses on stability and performance. The main new features include support for multiple SIM cards, high definition voice calls on supported devices, and the ability to join Wi-Fi networks and manage Bluetooth pairings through Quick Settings. The biggest new feature is "Device Protection." They say, "With Device Protection, your lost or stolen device will remain locked until you sign in with your Google account — even if someone resets your device to factory settings. This feature will be available on most Android phones and tablets shipped with Android 5.1 in addition to Nexus 6 and Nexus 9."
