As we prepare to see the release of Android 12 this month, Samsung is rolling on with its consistent monthly security patches. For October 2021, several Galaxy smartphones are already seeing Samsung push out updates. Here’s the full, continuously updated list.

Samsung first started rolling out the October 2021 security update on September 28 to the Galaxy S21 series. The update, so far, seems to have no user-facing changes and weighs in at around 300MB.
Devices with Samsung October 2021 security update
Which devices will be getting the October 2021 security update from Samsung? The company’s list is, as usual, quite long, with over 40 devices qualifying for monthly updates, over 60 for quarterly updates, and over 40 more for biannual updates. For those lesser-updated devices, it’s unclear exactly how many will actually be updated, especially as recent months have seen many of them updated.
