Agreed but they do drop support for older pixel devices very very quickly which is kinda of PITA. At least the Pixel 8 is supposed to be supported 7 years.
GrapheneOS provides extended support for end-of-life devices but we strongly discourage using our extended support releases. You can see we do that from https://grapheneos.org/releases and https://grapheneos.org/faq. We set an accurate Android security patch level field and do not downplay it with inaccurate claims about it. We do not do what other alternate operating systems by splitting out a Vendor security patch level field and claiming to provide all open source patches which is fundamentally not possible especially considering that a lot of the firmware is based on open source projects.
Our hardware security requirements are listed at https://grapheneos.org/faq#future-devices. Pixels are the only devices providing the requirements we set for updates and the list of security features. They also provide proper alternate OS support where all those security features work correctly. Samsung has most of the expected features and provides a similar length of support and number of major yearly updates but is missing the proper alternate OS support, MTE and the monthly/quarterly updates.
Each month, there's a new Android release which are distinct from the partial backporting of privacy/security patches to older versions. It's not monthly security releases but rather monthly performance/security/feature releases with separate backports of all Critical/High severity patches to older versions. Android 14 and Android 14 QPR1 are older versions of Android, and there are security backports to Android 14 separate from the monthly releases. This is currently fairly exclusive to Pixels. Samsung is getting much better at doing the security backports and are reducing delays for major updates but they're still acting as if the monthly/quarterly releases don't exist.
I understand that from a security perspective, but from an e-waste perspective even the current 7 years support is disastrous let alone the previously 3-5 years that vendors.
Not everybody has the same security needs, I often gift my older phones to my family members and if I have the choice to leave them on a fully unpatched device vs a GrapheneOS that is a "best effort" patch I will happily choose GrapheneOS.
I am super glad for all the work you guys do in any case, you can only love from me and I am honestly not buying an phone that doesn't support GrapheneOS at this point.
Extended support is very difficult to provide in a way that fits into the expectations we have for robustness, app compatibility and security beyond the lack of incomplete patches. For example, it would be easiest for us to move the Pixel 4a (5G) and Pixel 5 to Android 14 QPR2 to avoid having a separate legacy Android 14 QPR1 branch where we need to apply backported AOSP patches which sometimes don't apply cleanly. However, the Pixel 4a (5G) and Pixel 5 do not officially supported Android 14 QPR2 but yet had a bunch of changes related to it done to their repositories. We also build the vendor image ourselves rather than using a prebuilt one, so it always gets built with the latest SELinux policies, HALs, etc. available in AOSP. Quarterly releases are now trunk-based so it's similar to the major yearly releases. Moving Pixel 4a (5G) and Pixel 5 to Android 14 QPR2 is entirely possible. We could revert the QPR2 changes for them and use a QPR1 vendor build. The issue is that we know there are going to be regressions, and we do not want to ship dozens of serious bugs to users which we then have to invest substantial time in resolving. It's all time taken away from our focus on privacy features, security features, trying to have perfect app compatibility beyond apps forbidding using a non-Google-certified OS, etc.
We're very happy that support increased to 5 years for 6th generation devices and then 7 years for 8th generation devices because we will no longer feel the need to do harm reduction via extended support. It will save us a huge amount of time and concern about people continuing to use these insecure devices.
7 years for a phone that's used as a main personal phone is a long time. Most people aren't going to use it that long, particularly a flagship phone. It mostly benefits people buying it used. It would be quite strange to buy a Pixel 8 Pro and use it for all 7 years. The audience for using a phone that long is probably going to buy a cheaper phone. The main benefit is to someone buying a used device where it still has 4 years of support after someone replaces it after 3 years. We aren't a fan of people unable to afford new phones getting insecure used devices. This is a big step towards that not happening anymore. 7 years is longer than iPhones have been getting full support updating them to the new major OS releases with full security patches.
We worry a lot that we're encouraging people to keep using insecure devices by providing extended support but we feel we have to provide it with how many people are clearly still using the end-of-life devices. However, how much of the amount of people still using them is because they think they are fine due to continued GrapheneOS support? This bothers us.
Just a point of clarity, GrapheneOS has the same support window that Google does, so they're not dropping support earlier than the vendor. The reason they drop support is because the burden of supporting an EOL device is way, way higher, especially for a security-oriented OS.
GrapheneOS provides extended support for end-of-life devices but we strongly discourage using our extended support releases. You can see we do that from https://grapheneos.org/releases and https://grapheneos.org/faq.

Yes, we provide extended support for end-of-life devices which had less than 5 years of proper support. We provide that for at least 1 year and no more than 2 years. However, unlike other alternate operating systems, we're completely honest about the insecurity and do not downplay it. We do not falsely claim to provide all open source patches and do not set an inaccurate Android security patch level. We try to strongly discourage using the extended support releases. We plan to add a notification about this to the OS which people can disable instead of only clearly marking it as insecure on the site.
Taking the "vendor security patch level" into account, it is impossible in some situations.
If a critical vulnerability is found in a Qualcomm modem, wifi, or bluetooth firmware, there may be scenarios where this cannot be fixed at the OS level.
We have extended support for end-of-life devices but discourage using it and make it clear that it's insecure. We dislike needing to provide it and many people don't realize we do because we make sure not to hype it up and instead try to get people to move to secure devices with full patches available. 6th gen Pixels moved to 5 year minimum support from launch and 8th gen moved to 7 years so we do not think extended support will make sense after the Pixel 5a. For now, we reluctantly provide it. There's a good chance we'll port the end-of-life Pixel 4a (5G) and Pixel 5 to Android 14 QPR2 to keep providing what we call "extended support" with all AOSP/GrapheneOS changes instead of "legacy extended support" with just backported patches. It's very unfortunate they didn't just extend the 4a (5G) and 5 to match the 5a lifetime despite it having the same SoC. It makes our life harder.
Android doesn't have a separate vendor security patch level. It has a single security patch level covering all of the Android security bulletin and OEM security bulletin patches. Most alternate operating systems set an inaccurate Android security patch level where they redefine it to mean AOSP patches. They added a separate Vendor security patch level to put the real patch level. The whole thing is strange because the whole point is having a simple overall patch level and being honest about it. The standard Android security patch level only includes Critical/High severity vulnerabilities now, not Moderate/Low severity, and it doesn't include a lot of things that are deemed optional or out-of-scope. Can see this by looking at the Pixel bulletins where there are tons of patches that are clearly generic AOSP patches for all devices and patches tied to components like the Exynos radio clearly used by other devices. Android Security Bulletin (ASB) and the patch level derived from it does cover a LOT of drivers/firmware, but far from all or even most.
The missing patches for end-of-life devices include a lot more than outdated firmware in practice since drivers stop being updated and maintenance doesn't get taken over by others. The kernel drivers are open source but it doesn't mean someone takes over maintaining them. It's often mistaken as having all patches to open source code and missing patches to proprietary code but that's not accurate since updating AOSP is not updating all open source code. Lots of device specific code including even large parts of firmware is open source. As an example, Pixels use Trusty OS for the TEE and secure core, littlekernel for the boot chain firmware, etc. Security patches to those open source projects are security patches requiring new signed firmware updates to be released despite being open source patches.
They can have up-to-date AOSP but a significant portion of the OS consists of the driver, HALs, non-GKI kernel tree, etc. Android security patch level is meant to cover all of that. They're using it in a way that's not permitted for Android OEMs by redefining it to mean AOSP patch level for the parts of AOSP they build. Some things get built from AOSP for vendor executables and that are built into vendor executables. As an example with firmware, it will use the AVB library in the bootloader firmware. It also gets built into userspace driver libraries which are often proprietary, etc. Updating the portion of the OS they build via AOSP is not quite updating all the code from AOSP, and even if it was, the Android security patch level is not only for AOSP code. It covers firmware, drivers, etc. Check the recent Android Security Bulletins. The split Vendor security patch level shown in Settings is a LineageOS invention to show the REAL patch level for the overall device including firmware, drivers, HALs, kernel, etc. The whole point is meant to be that it's an overall patch level though. We just set the real patch level for extended support devices while providing the AOSP releases/backports. The only problem is the other alternate OSes making it look as if they're providing something more, but we aren't going to stop using it the official way. We're just not going to need extended support after the Pixel 5a since devices moved to 5 years and then 7 years of proper support.
