Another leaked list confirms which Samsung devices will receive Android 8.0 Oreo50
Basically, that would mean that the Galaxy S6 and all its variations should receive the latest Android 8.0 Oreo update at some point, even though Samsung has yet to confirm the information.
A list of Samsung devices that will supposedly be updated to Android 8.0 Oreo has just popped up on China's Weibo social network. Obviously, we can't vouch for its authenticity, but it's worth mentioning that it's been posted by a well-known Samsung leaker (ice universe).
The list is long enough to contain lots of devices, including the Galaxy S6, S6 edge and S6 edge+, as well as most of the 2017 Galaxy A series. Many Samsung tablets will receive the Android Oreo update too.
More importantly, it looks like the list contains the name of the new 2018 Galaxy A series smartphones, which haven't been announced yet: Galaxy A3 (2018), Galaxy A5 (2018) and Galaxy A7 (2018). Apparently, all of them will come with Android Nougat at launch, but they will be updated to Oreo at a later date.
