Google is now updating its Nexus 4 and Nexus 10 devices with Android 4.2.1 as an OTA update. The update fixes the notorious December birthday bug, which prevented any date in the month of December being selected as a birthday or anniversary in the people app. So far no any other differences have noticed in the new software, which carries the build number JOP40D. This bug has however been remedied with the introduction of Android 4.2.1. The OTA update is going to be deployed gradually, so users could be waiting weeks until the phone receives the new software.

Reports are suggesting that owners of the LG Nexus 4, the fantastic ASUS Nexus 7 and the new Samsung Nexus 10 are starting to receive firmware upgrade notifications that will take their Android installation to version 4.2.1. The Android 4.2.1 update comes in at a rather tiny 1.1 MB in size, it’s unlikely there will be a lot to pull out of it. Those who have Nexus 7, Nexus 4 or Nexus 10 should keep checking their devices over the next few days and install the 4.2.1 update immediately to ensure that December arrives with minimal fuss.
