Google Nexus 6-7

Nexus 6 owners on AT&T are reporting that Google's latest Android 5.1 Lollipop software is now being delivered to their devices over-the-air. The update brings a long list of new features and improvements, including anti-theft protection and greater control over notifications.

The update comes with build number LMY47D, PhoneArena reports, and it arrives one week after Verizon launched its own Nexus 6 with Android 5.1 pre-installed. Of course, the software is pretty much identical — if you take away Verizon's own apps.

We've put together a handy video that showcases all that's new with Android 5.1 for those who haven't been following it. There are a number of big changes, including the ability to switch Wi-Fi and Bluetooth connections from within Quick Settings, and separate volume sliders for notifications and media — plus a whole host of smaller tweaks and improvements.

But the update isn't without its own faults; one problem posted to the Android Issue Tracker suggests that the software has the same memory leak as previous Lollipop releases. There's no reason not to update if you're already running Lollipop, then, but it's worth bearing in mind that this release won't fix the issue.

Google is thought to have addressed the memory leak now, which appears to be affecting the Nexus 5 more than other devices, but it's unclear when a patch will be available to fix it. Hopefully the search giant won't make users wait too long.
