Samsung Galaxy A3 (2017) starts receiving Android 8.0 Oreo, but don't get your hopes up
However, if you're a proud owner of a Samsung Galaxy A3 (2017) don't get your hopes up, as this seems more like a limited rollout with just one country on the list of regions where Android Oreo is available for download, rather than a global deployment.
On the flip side, if you live in Russia, you will eventually be able to update your Galaxy A3 (2017) to Android 8.0 Oreo. The only thing we know about the update is that it includes the April security patch.
According to a report from Samsung Turkey, the Galaxy A3 and A5 (2017) are expected to receive Android 8.0 Oreo updates in early June, so if you don't live in Russia, then you'll probably have to wait two more months for the update to arrive.
