Samsung isn't slowing down in bringing the latest version of Android to more and more of its many mid-rangers. Right now, the rollout has reached the Galaxy A30s.
The update to Android 10 comes with One UI 2.0 on top for this handset, as well as the March 2020 security patch level. The new firmware version is A307FNXXU2BTD1. This has been spotted rolling out in Afghanistan, Iraq, Laos, Libya, Malaysia, the Philippines, Russia, Taiwan, Thailand, Vietnam, and the UAE. As always, expect this to make it to even more countries and territories in the near future.
The update arrives as a 1.5GB over-the-air download, as you can see from the screenshot above. If you are in one of the aforementioned places and haven't received the notification yet, perhaps it wouldn't hurt to manually check for the new release by going to Settings > Software update and tapping Download and install.
