No Project Treble on Android 8.0 Oreo for the Galaxy S8 and S8+
The Oreo update that's rolling out in Germany doesn't have Project Treble enabled, something we have confirmed using an official method that allows one to check for Treble support. Now, it's possible Samsung will implement Project Treble at a later stage, but if history is any indication, the company is likely to keep it limited to new devices, like the Galaxy S9 and Galaxy S9+.
There's also no guarantee that major software updates will come out faster on the S9 or future Samsung phones. Project Treble separates the Android framework from the low-level code that lets manufacturers make the OS work with their proprietary hardware, but since Samsung heavily modifies the Android framework, it remains to be seen what kind of a difference Project Treble will make.
