The One UI 3 update is now landing on the Galaxy A21s two months early


Last updated: March 29th, 2021 at 15:57 UTC+02:00

Samsung’s been doing a stellar job of bringing the Android 11 / One UI 3 firmware update to its eligible Galaxy smartphones and tablets, and in some cases, the company has even released the update ahead of the original schedule. It happened with the Galaxy Tab S6 and Tab S6 Lite, the Galaxy A50s, and now it’s happening with the Galaxy A21s.

The Android 11-based One UI 3 update for the Galaxy A21s is now being distributed in South Korea where it carries firmware number A217NKSU5CUC7. As many of you might recall, Samsung’s original plan for the Galaxy A21s was to update the device with Android 11-based One UI 3 in May 2021. But as we’ve seen with a few other Samsung devices in recent weeks, the Galaxy A21s is now getting ahead of the curve and is receiving the highly anticipated update about a couple of months earlier than expected.

The update is available in South Korea but Galaxy A21s owners in other markets should also be getting it soon, assuming that the initial release won’t cause any unforeseen issues. Galaxy A21s owners who may want to check if the update is available for download can do so by opening the Settings app on the phone, accessing the Software update section and tapping Download and install. As usual, readers can also refer to our firmware archive where the latest update should soon become available for manual download.

Thanks for the tip, Amin!
