Samsung starts rolling out the March security update for the Galaxy S21


Last updated: February 25th, 2021 at 19:28 UTC+02:00

Samsung is rolling out a new firmware update for the shiny-new Galaxy S21 flagship series, and as you’d expect by now, it includes the March 2021 security patch that was released earlier today for a handful of other Galaxy smartphones.

The changelog looks familiar as it mentions overall performance improvements as well as camera improvements, but it doesn’t offer any details. The update weighs roughly 387MB and Galaxy S21 owners can identify it by firmware version G99x0ZHU1AUB7.

Samsung has yet to detail the March 2021 security patch but it should address ot in a couple of weeks at most. Security patches are usually detailed a week or two after their release for, well, security reasons.

As of right now, the firmware update seems to be rolling out only in Taiwan, but Galaxy S21 owners in other markets should receive a similar update with the March 2021 security patch in tow soon. We’ll keep you posted and you can keep an eye on our firmware archive where you can download the latest firmware for numerous other Samsung devices.

Galaxy S21 owners in Taiwan should receive an update notification at any moment if they haven’t already, or they can attempt to trigger the update by opening the Settings app, accessing Software update, and tapping Download and install.
