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 shouldnโt be too long. After all, it hasnโt 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 Samsungโs custom Android implementation explains why the former is a bit late to start deploying. As a reminder, itโs been over six weeks since the September security update started rolling out to the same Galaxy A51 models.
Samsungโs ultimate Android 10 experience
As per usual, you can already download the original system images from our firmware archives. Thatโs in case you arenโt 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 doesnโt 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 isnโt getting the full scope of the update due to hardware limitations
