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.
June 2025 Android Security Bulletin was released June 2nd and our 2025060200 release incorporated those Android Open Source Project patches. Pixel stock OS released those and additional Pixel firmware/driver patches for the month on June 10th as part of the Android 16 release.
We ported to the new major OS release quickly and would have had an experimental release out on June 12th if AOSP 16 hadn't made things harder. Backporting the driver/firmware patches is problematic so we don't usually try but rather get the new release out very quickly instead.
In hindsight, it would have made sense to focus on the backports first since the port is taking much longer than planned. It'll be done this month and that's crucial to continue providing further security patches for July onwards along with security improvements beyond bug fixes.
