This is one of the best phone I have seen in the Galaxy S series. Samsung has brought a world class design, big without being bulky, with some good specs and usability you'd expect at this price. Its a lot more comfortable to hold on than S6 and feels a lot less plasticky because of having more metals.
It is having a 5.1-inch AMOLED display with quad-HD resolution, 2560x1440 and gives about 577 pixels per inch, which is still ridiculously dense!. And the panel is so excellent, with crisp colors and deep blacks. It's about as good as you can get — and visible excellent outdoors and full sunlight as well. And it's still impressive to see a screen that's as much as bigger with as much as resolution. Kudos to Samsung.
The speakers are front-face and much improved, less noisy compared to S6.
The camera is excellent, Combine with that an outstanding camera and you've got a phone that will serve just about anyone. The act of taking a picture remains as great as ever. Samsung's camera app is excellent, and feature-rich without being overwhelming with tons of options.
Its having waterproof. Not quite like having it in the pocket while swim, but it's good for a half-hour in about five feet of water. A quick dip in the shallow end shouldn't kill it.
An another more useful is, Samsung's fingerprint sensor which is tucked inside the home button. And its so good as ever and doing cool and quick.
All in all, it's a really good feeling in the hand. Premium!

The phone is looking so polish and good, The curved back and sides made it more comfortable to hold. some very slight rounding on the edges around the display is so nice, giving the phone a much more lux and contoured appearance than most.
It has 5.1 Inch display, a much better fit for me than a larger phone, also having shiny metal-and-glass backing which looks adorable and let everyone say "its beautiful".
While talking about camera, Samsung has made much improvements in the camera side and it is taking the pictures really really good, Scenes are brighter and colorful and do faster shots. Even in low-light scenes, It taking the photos fine, better than iphones. But, Digital noise was still there, just diminished sometimes. The key is it has very quick auto focus, grabbing clear shots of moving objects.
The front is having a 5 MP camera and taking photos fine, but not in low lights. It now has even more "beautification" filters than before, And the auto coloring makes our faces toned up more, skis as plastic, which makes our faces "Oh! Its mee?" sometimes.
Performance side, it operated smoothly and never lagged, and games played on its top-of-the-line processor with ease.
The battery lasted through a full day of heavy use.
