May Security update - Security express
CalyxOS 4.9.0 and 4.9.1 - May 2023 Security update is now available for Pixels, Fairphone 4, and SHIFT6mq
Released to stable on Thursday, 4 May.
This update initially rolled out in our new Security express update channel, which can be summarized in four words: Fastest updates, possible breakage.
The Security express channel
The Security express channel, which first debuted in April, allows us to achieve two major goals:
- Ship AOSP’s security updates faster, for users who want to receive security fixes as quickly as possible, even in the face of possible bugs.
- With your help, catch and fix bugs that appear after merging security updates, before they reach the Stable channel.
Promotion to Beta and Stable
- Most of the time, Beta will get the update in a few hours after Security express. Sometime it may be delayed if there’s major issues, however.
- Builds are bumped to stable after ample feedback from Beta and Security express, usually in a day or two.
Updating via Security express
- Open the Settings app on the phone
- Scroll down and tap System, then System update settings
- Tap Release channel, and select “Security express”
- You can tap “Check for updates”
- If it doesn’t do anything, make sure to check the “Permitted networks” setting

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.
