Google Updates Pixels With Important Security Patches, But Warns That There’s No Going Back

Google has started rolling out the May 2025 security patches to all eligible Pixel phones, tablets, and foldables, and the changelog is fairly minimal. But this one comes with a wrinkle — in order to block exploits from past versions, the bootloader has been updated with a new anti-rollback threshold. In other words, once you update to the May 2025 security patches, there’s no going back to older firmware versions.

The company announced today’s update on its product forums, noting that it has a build number of BP1A.250505.005 on most eligible devices. The update is being seeded to all of Google’s Android devices starting today, from the Pixel 6 through the Pixel 9a, though the company notes that the rollout will be conducted in phases over the course of the next week.

Google’s release notes mention fixes for poor microphone quality in some apps, Bluetooth pairing with certain smartwatches, and a bug where the device’s secondary language was erroneously displayed in the Quick Settings.

Unfortunately, there’s no mention of the delayed notifications bug that has been plaguing many Pixel users since the April 2025 update rolled out. We will have to test the new version for a day or two to see if this issue has been resolved.
