Nexus devices carry one big advantage over most all of the other Android devices; updates to the latest Android version are available for them first (most of the time).
However, as many Android users know, Google uses a staged rollout system for both their app updates as well as their system updates. This means that not all users get the update at the same time. Google says this allows them to make sure that the update is working how it should before they deploy it to everyone. For some of us, we just want the update as soon as we can get it.
That’s where Nexus Factory Images come in. These are the full Android package for Nexus devices, and they are available to download well before most people get the over-the-air (OTA) update pushed to them. Even better, it is incredibly easy to use these images to update your device on your own!
