Galaxy A51 now receiving One UI 2.5 update

Some international variants of the Galaxy A51 started receiving the One UI 2.5 update over the weekend, together with the latest Android security patch level dated October 1st, 2020. The rollout started yesterday in Russia and while it has yet to expand to more countries, the wait shouldn’t be too long. After all, it hasn’t even been a full week since the same software upgrade began reaching the Galaxy A71.

This particular release, build version A515FXXU4CTJ1, is targeting Galaxy A51 devices carrying model number SM-A515F. And the fact that it combines a new security patch with a more comprehensive update to Samsung’s custom Android implementation explains why the former is a bit late to start deploying. As a reminder, it’s been over six weeks since the September security update started rolling out to the same Galaxy A51 models.

Samsung’s ultimate Android 10 experience

As per usual, you can already download the original system images from our firmware archives. That’s in case you aren’t willing to wait for the One UI 2.5 update to reach you naturally and instead want to manually flash it onto your Galaxy A51. Backing up your data prior to doing so is strongly advised. And once your backup is in order, it doesn’t hurt to try triggering the over-the-air installation one final time by launching the Settings app, tapping the Software update item near the bottom of its menu, and selecting the Update and install option on the next interface that greets you.

As for the update itself, One UI 2.5 is essentially the ultimate version of the Android 10 experience Samsung put together for its smartphone customers. Among other things, it introduces various camera advances, expands Always On Display functionality to Bitmoji, and adds a wide range of minor fixes and stability improvements. The Galaxy A51 almost certainly isn’t getting the full scope of the update due to hardware limitations, but with no official changelog being available as of Monday morning CET, we’re still trying to figure out what exactly made the cut.
