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. 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.
