While most devices await an update to Android 4.1 Jelly Bean, Google has started rolling out the Android 4.2.1 Jelly Bean update for the Nexus 4 smartphone, which fixes the glitch that removed December from the People app.

Earlier in November, users of the Nexus 4 who managed to get their hands on the hot-selling device reported that the People app omits the month of December, and they were unable to enter event like birthdays or anniversaries. The bug, however, did not affect the Calendar app.

"Today I was inserting birthday of a friend in my contact list so that I can sync the birthdays in my calendar. I noticed that the December month is missing. When I pressed new event the calendar came but it was not having the option for the month December. I'm using Galaxy nexus running on 4.2 jelly bean which I installed yesterday on 14 November 2012. Please help me with this as I use the calendar a lot," reported a user.

The problem was addressed by members of the Android team in a Google+ post.

"We discovered a bug in the Android 4.2 update, which makes it impossible to enter December events in optional fields of the People app (this bug did not affect Calendar)," the Google+ post read. "Rest assured, this will be fixed soon so that those of you with December birthdays and anniversaries won't be forgotten by your friends and family."

Now, as promised, Google has pushed out a small 1.1MB Android 4.2.1 software update to address the bug. Per reports, the Nexus 10 to is receiving the OTA update.

TalkAndroid's Ed Caggiani reported that his Nexus 10 received the Android 4.2.1 upgrade around midnight. Android Central and XDA developers forums too have reported that Google's Nexus 4 and Nexus 10 devices are currently getting the new Android 4.2.1 over-the-air (OTA) update, which has the JOP40D build number.

The radio firmware version on the update remains unchanged from the previous version, and the hidden LTE option seems to be present in the latest software. Whether the software update has managed to address the recently reported camera bug on the Nexus 4 is currently not known.

Even though the Android 4.2.1 update is being pushed out currently, as is the case with most OTA updates, it will be a few days before all devices receive the software upgrade.
