Despite the Galaxy S8s may not be their flagship model, it should be clear that - as some have mentioned already - in the end companies will copy Apple. They've made so much fun of Apple for doing something that will definitely become mainstream. We have entered the times where wireless stuff have become mainstream. I for one can stream music to my hearing aids, for example. Bit buggy sometimes, and definitely not the same quality as AUX, but I wouldn't notice anyway, considering that I am hearing impaired (without my hearing aids I'd have to put the volume all the way up to 50% to hear at least something, 75% to get decent volume through my ears).
Also, I don't understand how they can continue to claim to have an 'edge-to-edge' display, while there's still some kind of chin. And I hate that camera hole in the screen.
