August Security update

The August update is here. It’s mostly identical to the Special Pixel 4a release (2.7.1), with the only addition being the security updates.

We’re working on some features and another update will be released later this month.


Pixel 2:

Note: The A2 proprietary firmware components are from September 2020 since trying to upgrade to anything newer ends up factory reseting the device.

Security update notes

  • The Pixels 3, 3 XL, 3a, 3a XL, 4, 4 XL, 4a, 5, 4a (5G) contain the full security patch, as they are still being updated by Google.
  • The Pixels 2 and 2 XL are not being updated by Google anymore, so they only contain the fixes to the open source components, such as the OS code and the Linux kernel. Proprietary components such as the bootloader, modem firmware, and other firmware no longer get updates.
  • The Xiaomi Mi A2 is still getting security updates, but those are Android 10 and usually released towards the end of the month, whereas CalyxOS is Android 11 and releases the updates right as they're available. This means that the A2 lags behind slightly, by a month or two, in getting security updates for proprietary components.
