As of this writing, the Galaxy A11, model number SM-A115M is receiving the One UI 3.1 update and a newer security patch in Panama. The latest release is identified by firmware version A115MUBU2BUE1, and availability will of course expand to other regions soon.
The latest firmware should include a newer security patch but, evidently, the most exciting thing about this release is Android 11 / One UI 3.1. Although Galaxy A11 owners shouldn't expect any advanced flagship-grade features from this new firmware, they can at least look forward to a redesigned UI and a few quality of life improvements.
The update is being rolled out over the air and customers should be able to trigger the update process — where available — by opening the Settings app and accessing Software update. SamMobile offers an alternative method of acquiring updates from our firmware archive for readers who may want to skip waiting for the OTA release.
Thanks for the tip, Amin!
