South Korean manufacturer Samsung launched the Galaxy A8 (2018) with Android 7.1.1 and the Samsung Experience 8.5 UI. While the company has updated many Galaxy series smartphones like the Galaxy S7 series or the 2017 A-series, but the 2018 A8 series is yet to get an official update. The A8 is one of the major mid-rangers this year, but the development team has been too busy providing updates for other smartphones and hence the delay.
According to two new reports from GalaxyClub and SamMobile Samsung has started working on the Android 8.0 Oreo update for the Galaxy A8 (2018). The smartphone currently runs on firmware version A520FXXU2ARD1 while the one that the company is working on is A530FXXU2BRDx showing a transition from A to B. Such changes also occur with updates with new features without changing the Android version but its highly unlikely for a smartphone like Galaxy A8 (2018).
The firmware version is still in its early stages so we can expect at least some weeks before it is rolled out. Also if we go by the timeline, the Galaxy A5 (2017) was updated to Android 7.0 Nougat in August while the A5 (2016) got upgraded at the end of July. We can expect the same timing with the Galaxy A8 (2018) series. We can expect a few small Galaxy A8 updates before the company rolls out the final one. These small roll outs will only include the new security patches.
