Google has already started the rollout of Android 4.2.1 Jelly Bean update to Nexus 4, 7 and 10 devices. The update is meant to fix a bug in the Calendar and promises to improve performance and stability.
We reported a few days ago the Android 4.2.1 update was available as manual download to Galaxy Nexus takju owners.
Today, the folks over at MobileSyrup report the small update has arrived for Galaxy Nexus yakju devices as well.
The new version is pushed to users OTA (over the air) in waves, so not all Galaxy Nexus owners might receive it at the same time.
Aside from bringing back December to the People application, this update adds several fixes and improves performance and stability. It will bring some new cards in Google Now and new features for the camera.
