If you recall a few days ago, someone in Vietnam accidentally received an Android Oreo update to their Galaxy S7 edge, complete with the same Samsung Experience 9.0 that is already rolling out to the Galaxy S8 and S8+.
Well, it turns out that more than one person got that same update in Vietnam, and one of them offered a system and kernel dump so that a flashable ROM could be made for folks with the Exynos-powered S7 edge with an unlocked bootloader.
Thanks to this dump of information, a member of XDA-Developers was able to quickly compile a functional ROM that is based off of the leaked software from Vietnam. With this, users will be able to experience Android Oreo much earlier than Samsung would release the official update for the last-gen flagship.
Of course, flashing such unofficial ROMs is not recommended if you donít know your way around unlocking a bootloader, flashing a custom recovery and downloading ROM files. If youíre not familiar with any of these things, we donít recommend you do this as you could possibly brick your smartphone.
If youíre feeling adventurous, head to the Source link and read everything thoroughly before proceeding.

He could be referring to edge screen. Some folks aren't fond of such screens, so it might be the reason he says that S7 is better than S7 edge.
