CalyxOS 4.7 - March 2023 Quarterly Platform Release and Security update is now available for the Pixels and the Fairphone 4

We test all builds before release, however we cannot test every single thing on every single device, it’d take too much time. That’s why we release the builds to beta first, and then to stable afterwards.

Unfortunately, due to a mistake we accidentally released a buggy update to stable for Pixel 6 Pro. A fixed build has since been made available. Our apologies for the incovenience.
