Just 5.4% of Android devices have so far got the Lollipop update, and only a small proportion of these are on the most recent release, version 5.1. Indeed, many manufacturers and carriers are only just rolling out their Android 5.0.2 updates, six months after Lollipop was first announced.
But while its partners drag their feet with upgrading their devices, Google is forging ahead with developing further updates to its OS. The company has now released its first factory image of Android 5.1.1, which is available to download from the Google Developers site.
Surprisingly, perhaps, the first device to get the update isn't one of Google's flagship phones or tablets, but the Nexus Player - the ASUS-built Android TV box, which hasn't grabbed too many headlines since it was first announced alongside Lollipop last October.
Google hasn't yet published release notes for Android 5.1.1, but given that the update is now in the wild for the first time, we probably won't have to wait too long until they're made available. There's no word yet on when the new Android version will make its way to other devices.
