Google today announced a new version of Android that promises to clean up some bugs. Android 5.1 Lollipop improves stability and makes other minor improvements. In addition to the cleaned-up code, Android 5.1 also adds several features. For example, Device Protection prevents a lost or stolen device from accessing mobile networks without the original owner's Google password - even if the device has been reset to factory settings. The update also adds native support for multiple SIM cards, and improves HD voice performance on the Nexus 6 through T-Mobile and Verizon Wireless. Last, Android 5.1 makes it easier to manage Bluetooth and WiFi settings (especially device connections) from the Quick Settings menus. Google expects to roll out Android 5.1 to select devices over the next few days.
