Google today announced the rollout of Android 5.1, an update to the existing Lollippo OS, improving stability and performance. The update also introduces a couple of new features - support for multiple SIM cards, Device Protection and HD voice compatibility.
Device Protection is a feature that keeps your lost or stolen phone locked, until you sign in with your Google Account. This nifty feature stays in effect even if the thief resets your phone to factory settings, though it makes us wonder how much information is retained on the device even after a factory reset. The feature will be available on compatible devices shipping with Android 5.1, including the Nexus 6 and Nexus 9.
High Definition voice allows for crystal clear calling between compatible Android 5.1 devices, like the Nexus 6, on T-Mobile or Verizon. Android 5.1 Lollipop also provides enhancements such as the ability to join new Wi-Fi networks and control your paired Bluetooth devices directly from Quick Settings.
