Samsung Galaxy A51 gets stable One UI 3.0 update in Russia; global rollout to follow suit soon.
Now that the Android 11-based One UI 3.0 update is available for most previous-generation Samsung devices, it is only a matter of time before the software trickles down to the company's vast repertoire of mid-range smartphones. The latest recipient of One UI 3.0 is the Samsung Galaxy A51, the successor to the massively-successful Galaxy A50. Currently, it is only available in Russia, but a global rollout should follow suit soon. If it hasn't arrived on your device OTA, you can try sideloading it onto your Samsung Galaxy A51 via Samsung Smart Switch.
The One UI 3.0 update for the Samsung Galaxy A51 (firmware version A515FXXU4DUB1) is bundled with the February 2021 Android security patch. Previous iterations of One UI already had several 'new' Android 11 features such as an in-built screen recorder, advanced screenshot capture tools and even Nearby Share; hence the changelog isn't as impressive as One UI 2.0. That isn't necessarily a bad thing, as it is a testament to how Samsung stays ahead of Stock Android when it comes to features.
One UI 3.0 adds several key features to the Samsung Galaxy A51, such as enhanced privacy and permissions options, scoped storage, notification bubbles, improved Digital Wellbeing stats and a slightly redesigned user interface. Another critical feature missing from all Samsung devices is installing security updates via the Google Play Store using Project Mainline modules. For reasons best known to Samsung, none of its smartphones has A/B partitions, essential for seamless updates.
