Samsung vowed us all with how quickly it released the stable version of Android 12 and One UI 4.0 for the Galaxy S21 series. Samsung's first official Android 12 update came less than a month after Google's, which is the fastest the company has ever put out any new version of Android.
However, as is often the case, the update wasn't released in every market around the globe on day one and is still making its way to some countries. And today, it has arrived in Canada, where Galaxy S21, S21+, and S21 Ultra owners can download it over the air from their phone's Settings » Software update menu. Our firmware archive also has the Android 12 firmware ready for download should you want to do a manual upgrade.
This is the same update that has been rolling out elsewhere over the last couple of weeks. One UI 4.0 brings plenty of small little enhancements over One UI 3.x to improve the user experience, along with a few big new features, all of which we detail in the video below. Naturally, Android 12 itself brings many improvements and enhancements, as well. The update also bundles the November 2021 security patch, which isn't the latest at this point but isn't exactly outdated, either.
