[Samsung Galaxy S7 Questions and Answers] Linked Devices:
too many to list. but I guess off the top of my head:

the display:

literally the best consumer display in the world with virtually perfect professional reference level color fidelity, paper-like clarity with no diagonal edge bias (due to innovative proprietary diamond subpixel arrangement), infinite contrast and eye punching brightness that maintains perfectly even saturation and contrast unlike with lcd. Moreover the Screen calibration feature allows for various color space standards which is a must-have for professional photography or graphic work. Extremely High sensitivity screen allows for gloved use. Only just enough bezel to allow for screen edge swiping with a case installed leaving the device as narrow as possible making it much more nimble for one handed use and a bit less pants pocket stretching. Always on display is great as it allows me to check the time, date and notifications without having to turn on my phone--far superior in so many ways to the old way of decoding the color and speed of the flashing led.

Samsung pay:

their proprietary technology allows the device to simulate a magnetic card swipe which works anywhere unlike android pay and apple pay which only work on certain terminals. It constantly amazes everyone.

IP68 water and dust proof:

As beautiful as the S7 is it is indeed a fingerprint magnet. This is a problem with many phones so stylishly slick but unlike other phones when the S7 loses its lustre you can simply rinse it off under the sink and polish it off with a bath towel--good as new.

Powered USB otg with support for so many add ons:

gaming controllers, midi keyboards, file storage, keyboards, mice. I was surprised to find that I can charge another device with my phone and even spin up and operate a USB hard disk without any need for additional power cables.

the camera:

so amazing I use it for augmented vision. Not only can I inspect from the distance whether that little spot on the wall is a fly or a spider without getting off my lazy ass but I can see and read things where it would otherwise be far too dim for my eyes to see without need for additional lighting. Oh yea, and it also takes amazing pictures in just two clicks. I never miss a shot because even in the rare times when I would I can rely on motion photo to reverse time and recapture the picture just how I wanted. The expanding library of camera modes just kick it over the edge of awesomeness. In real world use I tend to switch between auto, pro, rear selfie, slow motion, and gif maker. I use burst a lot too which is available whenever you press and hold the shoot button.

ui:

I've found split screen and pop up mode more and more useful for working with and between multiple apps. Web browsing and reading while streaming music or watching YouTube and/or chating just feels great. I use my laptop so little these days which is so much better for my posture. Text selection is also improved paired with the hypersensitive screen. You can rely on the precision of the tip of your thumbnail and not the blunt tip of your finger. The adjustable dpi hack gives you more work space immediately expanding the usefulness of large screen.

I haven't even begun to touch on so many other things but I can definitely go on if anyone wants me to.

This is by far the most satisfied I've ever been with a phone and I've been using smart phones since when they were called PDAs. I never thought I'd be so satisfied with a non rooted android device but I don't find myself missing anything except perhaps the stereo sound hack and the Xposed framework but with all the features I'm discovering and looking forward to the gear vr Im sure I'll find enough ways not to care.
