The Galaxy M31 became the first mid-range/non-flagship phone from Samsung to be involved in the One UI 3.0 beta program, and now it's become the first mid-range phone from the company to be receiving the stable Android 11 and One UI 3.0 update. As expected, the update has been released in India first, with firmware version M315FXXU2BUAC and the January 2021 security patch accompanying it.
It's unclear if the update is already available over the air for either beta users or for those on Android 10, but you can check on your M31 by opening its Settings app, selecting Software update, and tapping Download and install. If it doesn't show up, you can download the Android 11 firmware from our archive and install it on your Galaxy M31 using a Windows PC to skip the wait. Just be sure to backup all your data before doing so.
How many more Android and One UI updates will the Galaxy M31 get?
This is the Galaxy M31's first major Android OS upgrade, and Samsung should provide it with another big update before restricting it to security updates. Samsung could even bring it two more big Android and One UI updates, but it's not something the company has officially confirmed for any M series device. Only select A series phones and all of the flagships launched since and including the Galaxy S10 are guaranteed three Android OS and One UI upgrades for now.
