Other than that I truly don't understand why people think the S8 is so far ahead of the 7 Plus. I've had the chance to use it a few times and it's a beautiful phone, but that doesn't make it a more useful phone.
When you say "use it", do you mean a full day where its your main driver. Or you've been in a store and played with it?
I've been using it for the past few days as my main phone and honestly...there's no question. It absolutely is ahead of the iPhone 7/plus. That's not a knock to the iPhone. I still love my iPhone. But man this S8 is a beast.
A few features I've found myself using quite a bit.
Split screen
The ability to play videos within the browser. On my iPhone, videos take up the entire screen when activated. On the S8 (and probably other android devices) the video can be played embedded, or enlarged onto the entire screen.
The screen is beautiful and the images fall off the edge due to the lack of bezels.
Always on display makes notification checking easier than ever without sacrificing battery life.
Trusted locations means that while I'm at home, my phone doesn't require me to unlock the device. This is also true for when the phone detects it's in my pocket or on me.
Edge panels. The ability to swipe on the side of the screen to view sports scores, news stories or send a quick text, while still having an active application on the main display is very convenient. I can be in a text conversation, swipe over and check the latest sports scores, then send that information without ever leaving the conversation.
Bluetooth 5.0 obviously.
Setting default applications is a real plus in some situations.
Smart stay keeps the phone screen on when I'm reading something on it.
I still don't know why I can't type names in the dialer and my contacts pop up on my iPhone. But on the S8, and other Android devices, I can.
I think the important thing to remember is we are also comparing a recently released device with one that has been out for almost a year. Hopefully the next iPhone introduces some of these features. But I honestly don't think anyone can objectively say the S8 isn't ahead of the iPhone 7. The iPhone 7 absolutely does what I "need", but so does the S8. And the S8 does quite a bit more. Not sure of many features the iPhone 7 has that the S8 doesn't. Although there are a few that the iPhone arguably does better.
