Samsung recently announced a list of its devices that will receive an update to Android 8.0, via its Canadian website.
Here"s the official list:
| Dates | Devices |
|---|---|
| March 19 | Samsung Galaxy S8, S8+ |
| March 28 | Samsung Galaxy Note 8 |
| Spring/Summer 2018 | Samsung Galaxy S7, S7 Edge, A5, Tab S3 9.7 |
| "Later in 2018" | Samsung Galaxy Xcover 4, A8 (2018), J3 Emerge, Tab A 8.0 (2017), Tab Active 2, Tab A 10.1 (2016) |
This timeframe does not necessarily apply globally, as it may differ slightly - European and Indian models of the Galaxy S8 and S8+ are already running Oreo since last month, as are select Note8 devices in the US in a slow rollout. It will accurately apply only to Canada, though it may be used as a rough frame of reference for other regions.
