The last update of 2019 is rolling out this morning to all Google phones, including — for one last time — the original Pixel and Pixel XL. Rolling out with factory/OTA images now available, the December security patch makes the usual bug and security fixes.

There are 15 issues resolved in the December security patch dated 2019-12-01 and 27 for 2019-12-05. Vulnerabilities range from moderate to critical, with the most severe relating to the media framework and a remote attacker possibly executing arbitrary code through a crafted file. 

In the Android Security & Privacy 2018 Year in Review, Google notes that “no critical security vulnerabilities affecting the Android platform were publicly disclosed without a security update or mitigation available for Android devices.” Additionally, there was an 84% year-over-year jump in security patches during Q4 2018 compared to the prior year.

This is the last update for the original Pixel phones introduced in 2016 that kicked off the Made by Google lineup, and includes all features and fixes in the November patch.


Update 12/10: The December security patch is now available for the Pixel 4 and Pixel 4 XL. In addition to bug fixes detailed last week, it’s accompanied by the first Pixel Feature Drop that introduces signature new functionality like automatic robocall screening and improved Google Duo conversations, as well as memory improvements.


The dedicated bulletin for Google’s phones and tablets lists 8 security fixes, while many Android 10 features that debuted on the Pixel 4 are now available for older devices. The December security patch brings Pixel Themes and gesture support for third-party launchers, while Live Caption is now available on the Pixel 3 and Pixel 3a.
