The Samsung Galaxy A51 released back in December 2019 is receiving the Android 11-based One UI 3.0 stable update.
The new firmware comes with version A515FXXU4DUB1 and bumps up the Android security patch level on the Galaxy A51 to February 2021. The update also comes with an improved UI and includes the usual Android 11 and One UI 3.0 goodies, which include chat bubbles, dedicated media playback widget, and Always-On Display customizations.
The One UI 3.0 update for the Galaxy A51 is currently seeding in Russia, but other markets should get it soon.
For Russian folks, they will receive One UI 3.0 on their Galaxy A51 any moment now, but if you can’t wait for the update notification to pop up on your device, you can head over to the Settings > Software update menu on your smartphone to check for the update manually.
