Samsung's get March update
The March security update is being rolled out a bit slower than we are used to with several brands. So too with Samsung. Still, the update is not forgotten, and three devices are now being updated with this patch. As of now, the update can be brought in for the Samsung Galaxy A36, the Galaxy A56 and also the Galaxy A53. Among others, Han reports the update rolling in on his device.

Looking at the changelog, we don't see any major changes. Despite the updates topping 400MB in size, and this one on the A53 is also nearly 300MB in size. On top of Google's patches, Samsung itself has also added patches of its own. In doing so, manufacturers often bring performance improvements and bug fixes.
All three devices can download the update as of now. You will get a notification when you can download it. If you haven't had a notification yet, you can manually check for updates via system settings.
Update 14:37: Han informs us that the Galaxy A54 will also be offered the update.
