We previously shipped our builds of Android 16 kernel drivers along with the new Pixel SoC firmware and cellular radio firmware. Today, we'll be making a release with the new Wi-Fi/Bluetooth firmware, TPU firmware and RIL code. This will provide the Pixel 2025-06-05 patch level.

We want to backport a few more things such as the userspace Mali driver library to make sure we have all the important patches.

Our initial Android 16 port was finished days ago and we've made a lot of progress towards replacing the device support which was dropped from AOSP 16.

Pixel patch levels include more than the baseline Android patch levels and we intend to include all of that before claiming to have the latest patch level. It's not supposed to only mean the Android Security Bulletin patches but rather ASB + a bulletin from the device vendor.

GrapheneOS is fully Android 16 and gets security updates in a timely fashion since this post. Google only seized to publish the device trees, which means that AOSP was no longer built to run on Pixels mostly OOTB.

All the other Android devices do not have their device trees published and so many AOSP distribution developers are familiar with that. This only disrupted us doing a port to Android 16 super quickly like we would do with 14, 15 etc.

We use a script called adevtool that automates a lot of the port and building process. You can check it out here:

adevtool downloads factory images / OTA packages and extracts the firmware, overlays, and more from them. Also supports Beta builds of future Android versions, so it's helpful in porting firmwares from them if they have an early security fix or something. The original developer created it for their distribution but with GrapheneOS input and some funding.
