Pixels used to have far better updates than any other Android devices but they stopped improving it years ago. It should have kept improving because it's not at all adequate. They need to be able to release OS updates more than once per month and it shouldn't take months for patches to make it into the OS. It currently takes them at least around 2 months to get even the most urgent patches into the OS. They could fix emergency calls being broken if the patch was made around 3 weeks before an OS release, but that's about as quick as they can go. It's not at all adequate for security and is a complete joke compared to Chromium's release cycle. They can get an emergency Chrome update released within a couple days. They should at least be able to do it for the Pixel OS in a week.

GrapheneOS is often around 4 to 6 months ahead on merging Linux kernel LTS releases. We used to handle this ourselves but switched to the Android GKI LTS branch maintained by Greg KH. Unfortunately, it was often struggling to keep up even before the absolutely massive increase in Linux kernel security patches this year. AI models have rapidly accelerated vulnerability discovery and it's an ongoing crisis for the Linux kernel. We want to be on the latest LTS revision within days and want to be using the latest LTS branch within months of it being released. We're not at all happy with how Android is handling things and plan to fix that ourselves. We'll get things back to how they should be.

We also ship all the AOSP userspace patches months before Pixels due to shipping all of the security preview patches as soon as possible. There are sometimes minor regressions but we find and fix them ourselves downstream. The security preview system has a terrible design especially considering that frontier AI models can reverse engineer the patches. There should at least only be a source embargo for around 24 to 72 hours rather than pretending as if it can work with the patches available 2 to 6 months in advance.
