Google has now begun to roll out new December 2019 update to all supported Pixel phones. You can use this article to directly download the official factory images / firmwares for your device. These complete images can be then manually flashed, making them quite useful for immediate upgrade or even, the best route to get back to factory firmware after installing a custom ROM. The changes within this month’s update packages are focused towards security and reliability. Be sure to upgrade if you have been facing glitches or issues before.
While original Pixel phones have been dropped from support, Google is still patching updates starting from latest Pixel 4, Pixel 4 XL and going back to Pixel 2, Pixel 2 XL. Despite not carrying new feature additions or changes, these monthly updates are quite important as they ensure security and reliability. Being official, these updates will arrive via OTA automatically on your phone but that is, if you are running a purely stock phone. If you have rooted your device or have installed a custom ROM, you would be needed to download the firmware files first and then manually flash them.
Google Pixel Security Bulletin – December 2019
List of devices compatible with new December 2019 security patch are: Pixel 4 XL, Pixel 4, Pixel 3a XL, Pixel 3a, Pixel 3 XL, Pixel 3 and Pixel 2 XL, Pixel 2. Original Google Pixel series, as mentioned, would not be getting this update.
Prior to making these images available for manual download, Google starts pushing them directly through their update servers to compatible devices. We did see Check for Update functionality, which is built-in to the Android system, being fixed in the previous build so hopefully, it wont be causing any problems this time around. To check for an available update, go to Settings > System > System update > Check for update.
Apart from security here are some of the key new additions coming to Pixel phones. Some are fixes dedicated for the new Pixel 4 whilst there are others spanning a wider compatibility list.
