Previously, the XML files in the framework-res of the leaked Oreo beta had revealed code-names of several Samsung devices and it further gave us a hint that the company was experimenting with Android Oreo on these devices. But at the time Samsung's flagship smartphones which include Galaxy S6, Galaxy S6 Edge, Galaxy S6 Edge Plus, and the Galaxy Note 5 were not mentioned in the list.
However, XDA Developers have noted that all these smartphones are powered by the Exynos 7420 system-on-chip and that they are powerful enough to run Android Oreo. Samsung customer care reps had earlier also confirmed the device(s) would be getting the update, and one of them had even gone on to say that the update would be released around February. Surprisingly this is the month and we are seeing reports about Oreo update for Galaxy S Series devices.
As of now, Samsung hasn’t published an official statement detailing the list of devices due to receive the Android Oreo update, which means that owners of Samsung’s 2015 flagship phones have been left in the dark. Now, though, T-Mobile support pages for the Galaxy S6, Galaxy S6 Edge, Galaxy S6 Edge Plus, and the Galaxy Note 5 all mention that “T-Mobile and the device manufacturer have agreed to support a new software update.”
The software update in question is Android 8.0 Oreo, and the T-Mobile support pages state: “Phase: Complete.” This may imply that Samsung and T-Mobile have finished testing the Android Oreo update for the aforementioned devices and it’s ready to start being rolled-out, but we have no way to confirm this right now. It’s also unclear whether the Oreo update will be rolled-out to all 2015 Samsung flagship variants or only the T-Mobile variants of the Galaxy S6, Galaxy S6 Edge, Galaxy S6 Edge Plus, and the Galaxy Note 5.
But, I'll make sure that you will be acknowledged about this as soon as possible.
