Samsung Galaxy S8 and S8 + design
The holy grail of smartphone design has been making the entire device a touchscreen without limits for at least a few years. Rumors have been around for a full glass iPhone for a while, LG is on the same page as its G6, and we had time early this year with the impressive Xiaomi Mi Mix at CES. Undoubtedly companies are pursuing this dream, but is it only because they stuck to the idea? As if everyone was running to produce smart watches, while the “iWatch” was still a rumor, or is there a real benefit to end users?
The main features of the Galaxy S8 twins are their large screens: Infinity Displays, as Samsung sells them. Like the Galaxy S7 Edge (Review) last year, the screens of these phones curl around the sides to give a limitless look. The way these phones go on extends almost to the top and bottom of both phones. There is still about 1cm of space on both sides, but while the headset, front camera, and sensors can be pushed up, Samsung has made the decision to downsize its brand and the iconic physical home button.
Both phones are beautifully minimalist with their screens. Once you see them, just touch them, touch them and turn them between your hands. The polishing that Samsung has achieved here is impressive, and we have to say that these phones even blow the Jet Black iPhone 7 and 7 Plus. They only breathe luxury.
The front and back of the glass are bent at the sides to make a metal frame that forms a nearly perfectly coherent surface. Samsung has been making curved eyewear for generations, and relies on the benefits of this design, not to worry about a flat version of the Galaxy S8. The S8 and S8 + are extremely soft, but Samsung has managed to not get too slippery.
This is a key point in the fight of aesthetics against usability. Without a physical key, the fingerprint reader had to be hijacked. According to many testimonials, Samsung wanted to design a fingerprint reader on the screen, something that Apple has to contend with, but had to settle for a traditional sensor on the back. It is extremely difficult to reach, especially if you are left-handed. There is also a small ring around the lens of the camera, so it does not scratch easily, but it’s too easy to feel the ring and assume that you’ve found the sensor that leads to an even greater frustration. If the sensor is located at the back, it should really be centered under the lens of the camera.
Display and sound
But seriously, the Super AMOLED panels here are really incredible. The color reproduction in both is excellent and as always there are different screen modes in case your taste is more specific. The screens are bright enough to fight the hot spring sun and the viewing angles are also excellent. First, you’ll notice that the S8 and S8 Plus screens are longer than most screens. While many other smartphone screens conform to the 16: 9 widescreen format, Samsung has created the S8 displays with an aspect ratio of 18.5: 9. Why? To push more screen into the hand, for example. In addition, the length of the screen makes it very easy to manage multiple windows, such as those supported by Nougat.
But do not worry: your applications will automatically adjust to the full screen and look great. In the meantime, some videos are flanked by black bars because they can not fill the screen. Samsung is not the first to follow this path. Rival LG had the same idea when building its G6, which uses an aspect ratio of 18: 9 shorter and shorter.
Samsung calls these screens “Infinity Displays” and works with resolutions of up to 2960×1440, which is slightly longer than the usual Quad HD. Remember that I said “as big as”. The phones work by default with “Full HD +”, ie 2220×1080. You need to switch to device configuration to convince them to run in full resolution, which is absolutely necessary when starting some Gear VR games. There is also an option to reduce the screen resolution “HD +” or 1480×720 if you need to extend the maximum battery life. The screen adjusts to this resolution if you enable the most aggressive power-saving mode, and it’s not too bad either. The edges of the symbols and the text look a bit blurred, but not ugly.
The Galaxy S8 runs on Android 7.0 “Nougat” with the software suite and the user interface of Samsung Experience (formerly TouchWiz). The software includes a number of wizard features known as “Bixby”, designed primarily to interact with Samsung’s embedded applications and other compatible services. This feature allows you to use voice commands to perform phone functions, to generate maps displayed on a home page (replacing the Flipboard integration shown above) based on user interaction and camera searches.
Bixby will support third-party integration via an SDK. The S8 supports the use of a docking station, known as the Samsung DeX, to access a desktop environment similar to a PC on an external display, using a mouse and keyboard. On April 21, 2017, the phone’s official sales date, it was reported that the standard music player in the Galaxy S8 would be Google Play Music, continuing a trend that began with the S7 in 2016. For the S8, however, Samsung has partnered with Google to add proprietary features to the app, including the ability to load up to 100,000 titles in the cloud storage service. This is an increase over the 50,000 titles that users can normally load. In addition, new users will receive a free three-month trial for the service, similar to buying the Google Pixel smartphone. In addition, Google said that other functions will be added to the application exclusively for Samsung in the future, and that the Bixby Assistant is also supported by the application. Bixby replaces S Voice, the speech recognition technology previously found on Samsung Galaxy models.
In May 2017, Google announced that the Galaxy S8 and S8 + will support the company’s Daydream virtual reality platform after Samsung announced a software update for mid-2017 . Verizon has started implementing an update for its devices with the support of Daydream. The Galaxy S8 is one of the few Android phones to support ARCore, Google’s mixed reality engine.
Samsung Galaxy S8 and Galaxy S8 +
There are two versions of each model: international calls launched in India are based on the Samsung Exynos 8895 SoC, while those sold in North America use Qualcomm’s latest and greatest Snapdragon 835. two chips are extremely similar; In fact, both are manufactured by Samsung in its advanced 10nm manufacturing process. The name of Snapdragon is well taken into account, but buyers in India should not have the second highest score. Early reports showed that Exynos is equal to or even better than the last and best Qualcomm silicone.
The Exynos 8895 features four custom Samsung M2 processor cores and four ARM Cortex-A53 cores up to 1.9GHz, combining power and energy efficiency. There is also a built-in Mali-G71 ARM GPU, which offers up to 60% more graphics performance than ever before. Samsung claims that the Exynos 8895 supports cache coherence between CPU and GPU cores and reduces latency for complex tasks. There are also improvements to the multimedia decoder, the camera’s image signal processor, the LTE modem, and the encryption subsystems, as well as a new image processing unit to enable object recognition. and motion tracking. All of this benefits from the 10nm process in terms of improved energy efficiency and the ability to work much longer before speeds are accelerated by heat. We will use these skills in the Galaxy S8 brothers.
Both phones have 4GB of RAM and 64GB of storage space. They support dual SIM with 4G at gigabit and VoLTE speeds, but if you want to add more memory to a microSD card, you lose a SIM slot. You also get Wi-Fi 802.11ac, the new standard Bluetooth 5.0, which improves speed and range, NFC and GPS
The 12-megapixel sensors in the rear have not changed much since last year. That’s not bad, because they were good cameras to start; Do not expect big leaps in quality. The photos were equally well exposed with excellent color rendition. And as always, these dual-pixel cameras focus incredibly fast, and optical image stabilization does a great job of keeping the subjects sharp and clear. The low light output corresponded to the S7 cameras, which is not surprising, since both sensor pixels of 1.4 microns and apertures of f / 1.7 have. However, occasionally expect blurred focus and less focused focus when it is too dark. Samsung says it has improved the treatment line so there is no delay between catching a shot and getting ready for the next shot.
The S8 and S8 Plus also work as solid video cameras. They capture quality images of up to 4K with excellent color and minimal nervousness. I just wish that Samsung offers more flexibility: There is a registration button, and that’s it.
There is an improved 8 megapixel front camera with a wider field of view for group selfies. It also has an aperture of f / 1.7, so it’s pretty decent in low light and generally it’s a good performer. The selfies were clean, detailed and well colored, especially when looking at the AMOLED screen. Even better, you can raise your palm to take a selfie without the need for pimples.
Performance and battery life:
The S8 and S8 Plus are fast, effortless machines, and almost nothing I threw on them for a week of testing stuttered them. This is mainly due to the new and brilliant Snapdragon 835 and 4 GB RAM on board. Bixby is often a bit slow at startup, but it has not been painful to push through Samsung’s improved interface and jump back and forth between running apps. If that’s what the 835 can do, I can not wait for these things to be everywhere. Workday multitasking, games like Hearthstone and Dead Trigger 2, even gaming emulated GameCube games: everything went wonderfully well. Unconsciously, I stopped thinking about the performance completely. As expected, the S8 also killed him in our usual landmarks, almost nothing came closer.
Anyway, none of this would matter if the phones had really bad batteries. Flash News: You do not do it. The smallest S8 usually lasts between one day and a half and two days of continuous use. The largest battery in the S8 Plus brings me closer to two days with just one charge. It’s also set to its maximum resolution with the screen: expect better battery life when you mark the screens in Full HD + or lower.
They also do this in our standard video reduction test, where we place a video in HD with a brightness of 50 percent of the screen while the phones are connected to Wi-Fi. The S8 and its 3000 mAh battery lasted 13 hours and 27 minutes, just a bit better than the S7 and Google Pixel, and way ahead of the G6’s largest 3,300 mAh battery. The clear winner, however, is the S8 Plus and its 3500 mAh battery. It was recorded at 15 hours and 8 minutes, more than the Pixel XL, Note 7 and Moto Z Force.
The Samsung Gallery has been focusing on stories for a while. Stories are shared albums, so your friends can add their own party photos or just a story to a common theme. There are several image editing tools available, from simple cropping to creating collages, to a more powerful editor .
The Samsung Galaxy S8 + delivers a clean external output with an active external amplifier, which is not surprising given its pedigree. The volume was above average, so it was a big demonstration in general. When we infused our standard headphones, clarity was barely affected, making it another point for the Galaxy S8 +. Again, it was not the loudest smartphone, but it was the last quarter, so Samsung’s flagship showed another solid aspect.
There is no pre-installed video player app, so the gallery handles the default videos. Like the music player, you can take the traditional Samsung from the Galaxy Essentials collection in Galaxy Apps . Even if this is not the case, the Gallery application is up to the task. It has full subtitle support with advanced features to change its appearance. The application allows you to play only the audio track of the video. With the odd aspect ratio, which is not standard video format, you can watch videos in their original proportions (mostly 16: 9 videos with black bars on the sides or in 21: 9 format – black bars from top to bottom) they fill out the screen (which results in 16: 9 videos being mostly distorted, but still at 21: 9), or cuts a portion of 18, 5: 9. It also supports a popup view whose size can be changed with a pinch gesture: Do not look for grips for resizing.
You can download third-party video players and access the video enhancer feature of the entire system. We tested VLC, MX Player and BS Player and all were recognized correctly. Even YouTube worked. Touch the contrast curve and the color rendition to
