Galaxy M31s and Galaxy M51 pick up May security update

Two of Samsung’s Galaxy M series phones are picking up the latest security patch this week. These phones are the Galaxy M31s and Galaxy M51, both of which have received new software updates that bring with them the May 2021 security patch. These updates are rolling out in Russia and Brazil respectively and aren’t just about security, although we only have the changelog for the Galaxy M51’s update at this time.

And it’s a confusing changelog: Samsung says the update brings the Quick Share feature to the Galaxy M51 in Brazil, even though this is a standard feature that’s a part of any smartphone that is running One UI 2.1 or later. Perhaps the Brazilian models didn’t have the feature for some reason, but it’s more likely that the update brings those Quick Share improvements that have been rolling out to many other Galaxy phones recently.

The Galaxy M51 update also brings support for Google RCS and improves the overall stability of functions. Samsung has also applied the new personal data protection law introduced by the Brazilian government in 2020. Called Lei Geral de Proteção de Dados (LGPD), the new law is Brazil’s version of the European Union’s GDPR regulation and “attempts to unify the over 40 different statutes that currently govern personal data, both online and offline, by replacing certain regulations and supplementing others.”

As for the Galaxy M31s update, what changes it brings to the phone should be revealed soon as more markets begin to get it. For now, if you own either of these phones, you can check if the new update is available for your device by opening its Settings app, selecting Software update, and tapping Download and install. You can also grab these firmware from our archives and install them on your Galaxy M31s or Galaxy M51 manually using a Windows PC.
