Important update: end of CalyxOS support for Pixel 3, 3 XL, 3a, 3a XL, 4, 4 XL, 4a, and SHIFT6MQ

With this release (5.17.1), CalyxOS has stopped providing official software updates for the Pixel 3, 3 XL, 3a, 3a XL, 4, 4 XL, 4a, and SHIFT6MQ. This means these devices will no longer receive security patches, new features, and bug fixes. As of the time of this update, March 2025, the Pixel 4a (5G), 5 and 5a, and other newer Pixels are still supported.

We strive to extend our support as long as possible after a device reaches manufacturer’s end of support. However, our team can only provide fixes to the open source components, such as the OS code and the Linux kernel. As the manufacturer terminates updates for these devices, proprietary components such as the bootloader, modem firmware, and camera firmware will get no more updates.

As devices age, the amount of work to keep devices up to date against latest vulnerabilities grows at an exponential rate while trying to provide timely support for new devices. At this moment, we cannot guarantee the same level of protection for the following phone models despite our best effort to extend the life of devices that our users have trusted for years.

To ensure transparency, we are sending a reminder to these devices. If you have one of these devices, you will see an end-of-CalyxOS-support notification at each boot. You can disable this notification by going to Settings > Apps. Click “Show system” on the top right corner of the page. Then from the list of apps, select CalyxOS Update Client > Notifications and toggle “End of CalyxOS Support” off.

It is important to mantain your digital security and privacy. To ensure you can continue receiving updates, please consider shifting to a device that is still supported by us or the manufacturer.

Thanks for trusting CalyxOS to keep your device secure.

Note

  • Over-the-air(OTA) Updates: Starting from CalyxOS 7.2.2.0, CalyxOS updates resume automatically over the air. No manual install of updates needed. However, if you would like to manually update your CalyxOS device, see our OTA installation instructions.
  • Security Updates for Pixel devices: The Pixel 9a, 9 Pro Fold, 9 Pro XL, 9 Pro, 9, 8a, 8 Pro, 8, Fold, Tablet, 7a, 7 Pro, 7, 6a, 6 Pro, and 6 stock OSes follow a monthly release schedule in direct alignment with the AOSP security bulletin. However, Google has stopped publishing the source code for AOSP QPR1 and QPR3 releases. As a result, CalyxOS is not able to timely include updates of the proprietary components, such as the bootloader, modem, and vendor firmware, for versions based on those specific QPR branches. The CalyxOS releases for the above models only contain the latest fixes to the open-source components, such as the operating system and the Linux kernel. Proprietary components get updates as soon as the corresponding AOSP source code becomes available.
  • Security Updates for non-Pixel devices: The Fairphone 5, 4, Motorola moto g 5G 2024, moto g84 5G, moto g34 / g45 5G, and SHIFTphone 8 stock OSes follow a different security update release schedule, which is usually behind AOSP updates by a month or two. The CalyxOS releases for these devices only contain the latest fixes to the open-source components. Proprietary components get updates as soon as the stock OS update becomes available.
  • End-of-life: The Motorola moto g52, moto g42, moto g32, Pixel 5a (5G), 4a (5G), and 5 are no longer being updated by the manufacturer, the CalyxOS updates for these devices only contain the fixes to the open-source components. Proprietary components no longer get updated.
