Detailed Review Samsung Galaxy S7: The Perfect Accessory
Try to close your eyes and imagine the Samsung Galaxy S6, and in addition to the details, you think the S6 is missing to become a perfect smartphone. Then try to compare that with Samsung Galaxy S7. How do you feel?
Samsung Galaxy S6 is Samsung's answer to criticism from users that the design of the S line is not as high as the price and segment that Samsung is targeting. But are you satisfied with a high-end model with dual-sided metal bezel, but cannot expand the memory card, battery replacement and resilience as it appeared on Samsung Galaxy S5?
If you have questions, then Samsung has answers to help you. The Galaxy S7 comes with a microSD port back and water resistant, although it still has a lithium-ion battery that cannot be replaced (maybe the later Galaxy S models, too). Very generous regarding battery life for this new generation.
Samsung's flagship models are always at the forefront of photography, and the camera on their smartphones is usually among the best in the market. But this time around, Samsung has chosen a direction, which just seems to be a step backward for the camera: reducing the number of megapixels, but increasing the pixel size, with 12 million pixels with focus. In phase. The company promised S7's ultra-fast focusing speed, and the fact proved it.
The AMOLED screen has long ago torn down prejudice that is too flattering to the eye without the honesty, coupled with the best blend of color and color accuracy.

After five generations of loyalty to the lesser plush plastic design and receiving a lot of complaints from users and tech specialists, Samsung flagships have always been thought of as unmatched in price and value. High grade.
And Samsung responded to that prediction with the launch of the Galaxy S6 / S6 Edge last year with its high-end design with aluminum bezel and dual-sided glass, this philosophy is still maintained on the Galaxy S6 Edge + and continues to be. Perfect on the Galaxy Note 5. And of course, Galaxy S7 also carry a similar design with a few minor changes.
On the front, the glass enclosure Gorilla Glass 4 has been slanted lightly on both sides of the machine. This is a small change that you can easily ignore if not thoroughly reviewed but once you recognize, you will appreciate this new details on the design of Samsung.
The return of the IP68 standard is a remarkable change over the predecessor S6; the Galaxy S7 can withstand 30 minutes underwater at a depth of 1.5m, allowing users to peace of mind using the lips. Wet field. With the IP68 standard, Samsung's new model also has good dust resistance.
On the front, the Galaxy S7 is almost identical to Samsung Galaxy S6 with the front camera, proximity sensor, light sensor and speakerphone. As with the S6, the S7 is equipped with a notification LED on the left side of the speakerphone - a cut feature on the A series.
The physical Home button, an icon on Samsung's smartphone line, also has some minor changes. If the Home button appears more rounded on the S6, on the S7, the Home button takes the shape of a rectangular rounded corner.
And of course, the Home button on the S7 still comes with a fingerprint sensor that works as a hold button to open the phone. Because it's not a one-touch sensor, you cannot ignore the brightness, which you need to get used to if you're using smartphones from some Chinese carriers or new Nexus devices. To buy Galaxy S7.
On the back side, the Galaxy S7 inherits softly curved bundles from the Galaxy Note 5 that cover up the increased thickness of the machine. Samsung also said the rear camera on the Galaxy S7 only protruding 0.46mm against the back, which may be the reason Samsung expanded the size of the camera by 1.1mm. The camera is centered with a flash, and the heart rate sensor is on the right side, overall there is almost no change to the arrangement on the S6.
Sim slot is also a MicroSD memory card slot is placed on top of the machine. Version S7 1 SIM supports one nano-SIM and 1 MicroSD card while the 2 SIM version supports two nano SIM or 1 nano SIM and 1 MicroSD card. There is also an extra mic on the top of the machine along with the lack of infrared ports, and may not appear again on future Samsung devices.
At the bottom of the phone, we have a micro USB 2.0 port (not USB Type-C as you expect), speakerphone and 3.5mm headphone jack. The right side is where the power button is located, with the left side of the two buttons to increase or decrease the volume. A Samsung-style crucial physical system layout with the high-end finish, similar to other top-of-the-range products. The rim of the handset is the same as Samsung Galaxy Note5, only slightly different in size.
Feeling the Galaxy S7 on hand is very solid, although the machine is heavier but does not affect the handling experience compared to the previous model. Despite the dual-sided design, the Galaxy S7 does not provide a slippery feel, yet it fits very well with fingerprints.
Still 5.1 inches, but was a lot better. Over the course of three generations, the flagship Galaxy S uses a 5.1-inch screen and the Galaxy S7 QHD resolution (1440 x 2560) is maintained. The pixel matrices are arranged in the form of Diamond Pentile, which means that the green pixels are twice as large as the other colored pixels.
It's great that Samsung has increased its maximum brightness on the S7's screen compared to the S6. But it's still a bit lower than the S6 when it's in the sun and lets it automatically adjust the brightness.
The lowest brightness of the screen is 2.1 nit, which is excellent for reading or reading at night. The color of the Galaxy S7 is very honest if you are in Basic display mode. The other methods make the screen more flattering but at the same time lose the accuracy. Maximum color deviation (DeltaE) is 2.3 and average is at 1.7.
Samsung Galaxy S7 is equipped with a battery capacity of 3000mAh, a significant increase compared to the number of 2550mAh in the Galaxy S6. Although not replaceable, at least Samsung has increased the ability of the battery for users. Plus, the S7's charging speed is fast, although it only supports Quick Charge 2.0, instead of the latest 3.0. Samsung promises that loading time from 0 to 100% takes just 90 minutes.
Like last year's flagship models, the Galaxy S7 also supports wireless charging with Qi or PMA charging devices. Samsung also offers users high-speed wireless charging, which promises twice as fast a charge as the cable.
Findmobileprice.com test shows that the battery life of the Galaxy S7 overtakes its predecessor with 23 hours of 3G talk time, nearly 15 hours of video playback, and 9 hours and 30 minutes of web surfing. S6 very much.
Samsung Galaxy S7 comes with the latest Android 6.0.1 from Google with its custom TouchWiz interface. And of course the user interface of the S7 shares much in common with other Samsung models and is very different from the pure Android interface.
The machine's lock screen includes a time widget with two quick settings for access to the camera or dialer and users can customize the widgets to their liking. The S7 also features a double-click on the Home button to open the Camera for fast-paced snapshots.
Fingerprint security is retained from the Galaxy S6; fingerprint sensor is not a touch type, so you need to open the screen before you can use the fingerprint to unlock the machine, it takes a little time. Compared to other manufacturers. However, the fingerprint sensor on S7 works very well. And if for some reason S7 does not recognize your fingerprint in 3 scans then you will need to use the password set beforehand, and if the sensor does not recognize your fingerprints more 2 Again, the device will automatically lock within 30 seconds.
The Galaxy S7 comes with a new feature, Always-On, which consumes about 1% of battery power per hour. Always-On external date time display can also be used to display some predefined wallpapers. Packages of the Always-On theme can also be downloaded easily from the store.
The S7's Homescreen also shares the TouchWiz interface as in other Samsung models, and the application can be arranged as 4x4, 4x5 or 5x5. Galaxy S7 also supports theme change throughout the system for users, in addition to a pre-installed theme, users have many other options from the Theme Store.
Applications in the app drawer are listed in alphabetical order or according to the user's liking; the application search feature is also integrated. Alternatively, you can also opt out of the app drawer and put all the icons on the main screen.
The notification area of the default machine has many customizations. Users can customize or rearrange the settings to suit their purpose.
Split-screen multitasking is also supported on the Galaxy S7, although the 5.1-inch is a bit small to use this feature conveniently. And only Samsung supported apps can work with Split-screen. Also, the application launcher as a window is also available for some applications.
The Galaxy S7 has some smart gestures such as flip the phone to turn off the phone, swipe to capture a screenshot, double-tap the Home button to access the camera or make a call.
The Galaxy S7 comes in two different versions, a Snapdragon 820 version, and a version using Exynos 8890.
The performance test was carried out with the Exynos 8890, designed by Samsung itself with eight processor cores, four 2.6 GHz Mongoose and four 1.6 GHz Cortex-A53 power-saving cores. With the graphics chip Mali-T880 MP12 GPU. Although different regarding processor, both versions of S7 have 4GB of RAM; 32GB or 64GB of internal memory.
Galaxy S7 has the highest monolithic benchmark ever on Android machines. With four times the Mongoose clock can reach up to 2.6GHz, the performance of single-S7 is compelling but still behind the iPhone 6s.
Multi-core scores are even more impressive when the Galaxy S7 is the highest benchmark in GeekBench's multi-core test, far ahead of Android or yet the flagship product from Apple.
Comprehensive test with Antutu software gives us a broader view of the overall performance of the machine. And the Samsung Galaxy S7 once again took the lead with a score of around 130000, promising an excellent speed experience for the user.
On the graphics performance test, with the Mali-T880 GPU including 12 processor cores, the Galaxy S7 set a new record with 32345 points, followed by last year's flagship Samsung Galaxy S6 and devices. Was running another Snapdragon 810 chip.
Compared to the OpenGL ES 3.1 graphics point, GFXBench 3.1 Manhattan gives a perfect score for the Galaxy S7, almost unbelievably when the Galaxy S7 surpassed all of its flagships last year.
In conclusion, Samsung has continued to set a new standard for speed with the Galaxy S7. Along with outstanding CPU performance, a great graphics processing engine promises a monster of processing power.
Although we all know that the number of megapixels does not determine the quality of the camera, but with 12 MP on the S7 camera is apparently a "rebound" compared to 16MP on the flagship predecessor - Galaxy S6.
However, the pixel on the S7's camera is much larger than the S6 (1.4 micro vs 1.12 micron), the larger aperture (f1.7 vs f1.9) means better exposure, more focus points phase (12-million-pixel focus, very impressive) and retain the optical image stabilization system from S6 brother. The Galaxy S7 comes in two flavors: The Sony IMX260 and the Samsung self-made ISOCELL.
The camera angles of the S7 are not as wide as the S6, but they are much more vertical.
The camera still maintains the S6 with a combination of shooting and video capture. In there, the shutter button and the video button on one side and the quick customization on the other. Motion Photo features are quite similar to the Live photo on iPhone 6s and 6s plus, recording a 3s video and compressing it as a JPG file. But the limitation is that the image is only viewable in the form of Motion Picture on the Galaxy S7 / S7 Edge so that the sharing will be very limited.
Capture Mode Pro gives you the more customizable depth of field and the ability to adjust values such as shutter speed, exposure compensation, ISO sensitivity and white balance. Also, manual focus is also supported to help you master the camera in awkward or special shooting situations.
The camera of the Galaxy S7 produces images with very good quality and detail. Noise reduction is adjusted to handle interference in dark areas to provide a smooth overall picture. The reproducibility is almost the same as that of the S6.
The color reproduction is similar to the S6 when the picture has a vibrant color, which is appreciated by the general users. White balance works very well and accurately. The wide dynamic range, in high-contrast conditions, is usually handled to keep details of areas bright, leading to dark areas of detail that are considered to be a better direction than others.
Here are some shots were taken with the rear camera of S7:
S7 also supports HDR shooting; you can choose to turn on, off or in Auto mode. HDR shooting from the camera is very good at reconstructing and balancing details between bright areas and functional areas, giving a very natural image.
The lack of brightness is always considered one of the measures to judge the camera and S7 did not disappoint the user. When in low light conditions, the S7 produces sharp images and retains many details, resulting in better than its predecessor Galaxy S6. Some photos were taken in low light conditions by Galaxy S7:
Panorama capabilities of the S7 is impressive, giving the images with extremely high resolution and detail can be equal to the usual shot.
The 5MP front-facing camera is aimed at the high-end user segment, selfie shooting, aperture up to f1.7 and full-screen flash support. Image quality from the front camera is equivalent to the Galaxy S6. Pictures are good when in bright enough conditions, human skin color is reproduced in the real direction, but still with eyes. Fill flash with screen also helps you to selfie in low light conditions, a Samsung solution instead of equipping a flash for the front camera.
In terms of video recording capabilities, the Galaxy S7 supports 4K (2160p / 30fps), 1440p / 30fps, 1080p / 60fps, 1080p / 30fps and lower resolutions. We can even extract images with 8MP in 4K resolution video that retains the color retention compared to the photos taken from the back camera. The S7 also supports slow-motion shooting with 720p resolution with 240fps frame rate and Hyper lapse rotation. Videos from S7 are very smooth and detailed, but noise is still present in the dark. There is also a focus hunting phenomenon when recording 1080p / 60fps.
