Samsung are the indisputable kings of the Android world, but the company has been found wanting in the updates department, perhaps due to its impressive retinue of devices, or sheer obstinacy. A report on XDA-Developers has revealed the list of Samsung devices that will be updated to Android Oreo.
The source of the information is the firmware file for the Galaxy Note 8, so while it isn't exactly official, it's as close as it gets. According to the report, the company will update most of its current lineup of devices. Devices like the S8, S8+, and Note 8 are already on Oreo, of course. Mid-range and budget devices released in 2017—from the A and J series—will all receive the update to Oreo. 2016 devices to receive the update include the S7, S7 Edge, and A8 (2016). The Note 7 is not listed for obvious reasons.
A major omission here is the Galaxy S6. Reports a few months ago claimed that the device would receive the update but that may not be the case. It was released back in 2015, in any case, and an update to Oreo would have made it the first Android device to see three major updates.
While these devices are all billed to get their tastes of Oreo goodness, no one knows when exactly. Samsung is notorious for delaying updates, and it wouldn't be at all surprising to see some of these receive the Oreo updates in Q4 this year, or perhaps even next year.
