Android 5.1 announced, includes cross-platform HD Voice support

Google has announced Android 5.1 Lollipop, the latest update to its mobile OS, which comes with some improvements and new features. We have the usual stability improvements and performance-enhancing code supplements, but the new features might have you happy.

Android 5.1 now includes multi-SIM support, and cross-platform HD Voice support - depending on the network, of course. Google has also provided Device Protection, where Android will keep your smartphone safe from intruders, even if they perform a factory reset on your smartphone after they've stolen it. This new feature binds your Android 5.1-powered device to your Google account, unless you choose otherwise.

The latest version of Lollipop has an updated Quick Settings menu, giving you more granular control over things like Bluetooth and Wi-Fi network switching. The latest Android 5.1 update should be rolling out to Nexus 6 owners soon enough.
