About the /e/OS

When do /e/OS builds get AOSP security updates and vendor patches?

When we build /e/OS, we apply the security patches available from AOSP for this Android version (ie: Android 10, Android 11, etc…). AOSP is open-source, with both Google and a large community of developers, including /e/OS working on it.

The availability of an AOSP version for a given device mostly depends on how long the open-source community is ready to support this device. Sometimes technical blocking points require moving to a more recent Android version. It is also possible that the community, for example /e/OS, LineageOS or others, will back-port the latest security patches to an older AOSP version.

With /e/OS, we sometimes have the option to make an /e/OS version based on newer Android version to provide a longer lifetime to key devices. For example, your device is initially based on Android 11, but there is a new OS version for your device based on Android 12, this will mean that your device will get security updates for a longer period. This is different from vendor provided device patches. Which end, when the last stock ROM update is published by the device manufacturer.
