Samsung Galaxy S7 vs Samsung Galaxy S8

Samsung fans are able to preorder the Samsung Galaxy S8 and S8 Plus on March30. This phone will sell starting from April 21 in US and UK. In the market, Samsung Galaxy S7 and S7 Edge still hold a big part of smart phone users. Some of them have doubt about changing Galaxy S7 to S8. So in this article, we will have a brief look at the Samsung Galaxy S7 and S8. Here we collect some ideas from TechRadar.



Design
When you first see it, you will be forgiven for thinking the Samsung Galaxy S7 looks almost identical to the Galaxy S6. And that's because it is.



  • Rear curving makes it much nicer to hold in hand
  • Now waterproof, which adds a level of security to use
  • Can be gripped securely thanks to smaller bezels
  • Muffled single speaker



While the Galaxy S7 has the same size 5.1-inch display as the S6, Samsung has managed to shave off a fraction of the bezel around the screen, reducing the handset's height and width slightly.

The look of the Samsung Galaxy S8 is what will sell it to the legions of fans clamoring for a new phone from the brand - and to a wider audience as well. 



Every corner and edge has been rounded on the Samsung Galaxy S8, giving it a very pleasing feel in the hand. It's the Samsung Galaxy S7 Edge with a bit more courage in the design – Samsung has spent two years convincing the world that a curved screen is best, and the fact it's on both this handset and the larger Galaxy S8 Plus is testament to that effort.

That said, it's not a small phone. The 5.8-inch screen is packed tightly into the frame but it's still large at 148.90 x 68 x 8mm, and you'll struggle to reach all corners of the screen with a single thumb.

The fingerprint scanner is on the back, by the camera, and it's rather hard to use from the natural holding position for a phone in your palm. It is something you could get used to, but we're not sure why Samsung put it so close to the camera when it could have been closer to the middle of the phone.
However, we don't want to take away from how impressive the Galaxy S8 is in the hand, with the 5.8-inch screen squashed into an impossibly-small chassis – and one that packs in wireless charging and a IP68 rating, so you'll be able to immerse this phone in water and dust with little worry... and not even need to plug in a cable to charge it.

Camera
Although this camera has fewer megapixels than the S6, it takes better photos.
Scenes are brighter, which makes the action easier to see.



Even in low-light scenes, such as a Berlin speakeasy, the S7 trumps the iPhone 6S, yielding brighter, more usable photos. Digital noise was still there, just diminished; those small speckles of color that infiltrate the picture are an inevitability in low-light digital camera shots.

Whip-quick autofocus was also a winner, grabbing clear shots of moving objects, like swaying flowers.

In terms of the camera on the Samsung Galaxy S8, we're oddly seeing little in the way of improvement over the (admittedly impressive) snapper on the Samsung Galaxy S7 from 2016, despite promises to the contrary.



One of the big upgrades on board is to the multi-frame image feature, where three snaps are shot and the best is selected for you with each picture. It's not clear at this time whether this is an interpolation of all three pictures, in the same way as HDR on smartphones works for brightness and color, or if it's just the Galaxy S8 looking for the sharpest image of three.

The auto mode is rapid and takes brilliantly sharp images every time, the pro mode is slick and fully-featured, and there are a host of other modes (included background defocus, just like in the iPhone 7 Plus... although Samsung has been doing it a lot longer) to keep you interested with the snapper.

The front-facing camera has been upgraded to 8MP and is clear and sharp too – with a great low-light sensor once more we're confident this will be a great selfie phone.

Bixby
Samsung has shocked us in a small way by announcing Bixby, its own take on an intelligent assistant, before the lanuch of the phone. The Samsung Galaxy S8 is clearly the launch vehicle for the AI service, and there's even a dedicated Bixby key on the side of the Galaxy S8 so you've always got instant access to the portal.



We should probably talk about what Bixby actually is: it's meant to be a frictionless assistant that can follow you through voice, the camera or touch, learning what you want it to do, and not requiring you to know a specific set of phrases to make it work.

However, that's not what we saw at launch – what we saw was a slow and clunky imitation of every other voice assistant on a phone. At this point you can basically use Bixby to make a call, look up wine or work out places around you through image recognition.

Samsung has since been in contact to talk about Bixby, telling us that the demo we saw wasn't really indicative of the power of the service - we're hopefully going to be getting a more in-depth look at it soon.

Given that Samsung is making such a big deal about how Bixby will be contextual and understand what you want, when you want, it seems odd that it's being launched now at all. Google Assistant is still available on the Galaxy S8, and is arguably far more useful. For instance, you can still say 'Okay Google' and do all the things Bixby can and more... without needing to press a dedicated button.

That said, Bixby isn't a service for now. Samsung intends to build on it, make it available to all the apps on the phone and offer a software developer kit to the app makers in the future. 

These are not all the features of Samsung Galaxy S7 and S8. We will update the information irregularly.
