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.
