Google has made Android 5.1 Lollipop officially official, over a month after it began appearing on Android One devices in Indonesia. The update is largely routine, bringing in a few new features as well as a host of bug fixes and stability improvements. Those fixes were sorely needed, as Android 5.0 Lollipop shipped with a fair amount of bugs still in the system. But what about the new features?
Android 5.1 supports multiple SIM card slots, allowing you to use more than one number on the same device, which is handy if you share the phone or you have separate numbers for personal and work. Device Protection is a new feature that keeps a lost or stolen device locked until you sign in with your Google account, even if the device is restored to factory settings.
HD Voice is another new inclusion on supported networks and devices, allowing for clearer, crisper calls. The final change comes in the Quick Settings menu, which now allows you to connect to Wi-Fi networks and control paired Bluetooth devices directly from the Quick Settings.
While not a groundbreaking update like Android 5.0, this new version of Android brings in some necessary bug fixes and a few new features that should be pleasantly received. Google has said that today it’s rolling out the update, but it’s unclear if it’s actually pushing the update to Nexus devices or simply announcing that there’s a new update. I have yet to see anything on my Nexus 6 or Nexus 7, so it may not be happening quite yet.
