Just last week Google surprised us by announcing a new Android 4.4.1 update to KitKat on the Nexus 4, Nexus 4 and the LTE 2013 Nexus 7. You can now add the Nexus 10 to that growing list of devices which will soon get the newest update. Google has made the download link available for the KOT49E update on the Nexus 10. This update is 51.3MB in size and is coming from Google’s servers. It primarily just brings a number of useful camera improvements to these devices, although it includes a few other bug fixes as well.
If you want to update your Nexus 10 manually, here is the download link for the file: Google Servers - Nexus 10 Android 4.4.1 Update
