Google has begun rolling out Android 4.4 KitKat across its Nexus range, bringing its earlier tablets and smartphones up to speed with the Nexus 5.
The first devices to get KitKat will be will be the 2012 and 2013 wi-fi versions of the Nexus 7 as well as the Nexus 10, the Android team announced via Twitter.
Next up will be the Nexus 4 and Nexus 7 with mobile data, which will get the KitKat update "soon", though there's no precise date. The next devices that should get KitKat are Google Play versions of the HTC One and the Samsung Galaxy 4, but again, Google hasn't said when.
The KitKat updates bring Google's Nexus range in line with the Nexus 5, the first device that shipped with the OS that was released on October 31.
It will be some time before other Android handset owners can expect to see KitKat running on their devices. So farfor KitKat's arrival on its phones, which it expects to deliver to the HTC One from the end of January.
Sony and Google's Motorola have named several smartphones that will get KitKat, but neither have said when. Meanwhile, Samsung and LG have not announced their KitKat schedules.
Android users keen to break out of their carrier or device maker's release schedule may find some joy with the CyanogenMod Installer, published on Google Play. However, for now, there's no installer for KitKat, though the company says it is working on it.
