Samsung's Galaxy S21 series doesn't support seamless updates, claims report

It appears that Samsung’s recently launched Galaxy S21 smartphone series misses out on a feature that could have allowed its users to seamlessly update the software of the device.
For those unaware, the Android operating system comes with support to install system updates in the background, which means that users can operate the device while the software is downloading and requires a reboot only to install the update.
A report by Android Police suggests that last year a change to the Android 11 Vendor Test Suite was spotted that indicated that it would become mandatory for phones running on Android 11 to support this feature. However, as per the latest Android 11 Compatibility Definition Document (CDD), Google has seemingly walked back that requirement. As a consequence of that, Samsung has not offered this feature with the Galaxy S21, S21+, and S21 Ultra handsets.
“We can confirm that seamless updates are not present on our Galaxy S21 Ultra review unit, and AP's Max Weinbach has further confirmed the omission in a quick teardown,” said Android Police in a report.
So far, there is no official word from Samsung or Google on the matter.
