Even though it should and has plenty of power to support it, I doubt it. I personally like Samsung but they phase out phones way too fast. It's got an Exynos processor and 4GB RAM and can handle Oreo but I think Samsung will abandon it.
On a brighter note: if you're a bit brave you can root your phone, install customer recovery and dive into the world of custom ROMs which I'm sure someone will make an Android Oreo ROM here in the next few months...What carrier do you have?
