Samsung was once among the worst in the Android world when it came to updates big and small, but in 2021 they’re arguably better than Pixel. Now, Samsung is rolling out the April 2021 security update to its huge lineup of smartphones including Galaxy S21, S20, A52, and more.

The April security patch, technically, wasn’t fully released when Samsung started its rollout. Google follows a pattern of rolling out the update to its Pixel smartphones on the first Monday of every month, this month landing on April 5.

Samsung April 2021 security update — what’s new

That same April 5 date is when the changes and security improvements made in the patch are officially detailed. After Google rolled out the update to Pixels, official details on security improvements also finally arrived on Samsung’s site.

This month, Google issued 3 security fixes, all of moderate severity. Samsung further included 37 high-priority patches in this update with 6 critical severity fixes.

Often, Samsung will also bring minor UI tweaks to its monthly security updates, and the April 2021 patch is no different. As captured by the folks at SamMobile, one of the notable changes is an expansion of Portrait Mode. The feature was previously limited to the telephoto and ultrawide cameras only on some devices, but the April patch seems to extend functionality to the main camera.

The update also claims to continue working on touchscreen issues on the Galaxy S20 FE 5G. On Galaxy Tab S7, the update delivers a bunch of new features including virtual backgrounds for video calling apps, better multi-window support, and more.

Devices with Samsung’s April 2021 security update

Which devices are set to get the April 2021 update from Samsung? The list of devices getting monthly updates right now is quite hefty, and as of April 1, several models have already been updated. You can see devices that have been updated so far in the list below.

The list below is being updated as new rollouts begin or expand to new regions and carriers. New additions will be marked in bold.
