SAMSUNG GALAXY J7 Review (2017)

In the price category from 16 to 20 thousand rubles, the Galaxy J7 smartphone has many competitors. Is it enough advantages to attract the attention of buyers or will they give preference to other manufacturers?

You are reading a review from the portal, Original material was published July 25, 2017 of the year.


SAMSUNG smartphone Galaxy J7 last model was announced in Europe in June, And this review discusses the option from the American AT & T Communication Operator. Externally, it is no different, but the internal components are slightly changed. J7 has many incarnations and all of them are intended for the average price segment of the smartphone market. In this case, the device contains the features of the Galaxy J7 V model from the Verizon operator, which came out in March, and last year's Galaxy J7. The cost of the apparatus is about $ 240 and his competitors are quite a lot. You can call the Moto G series smartphones, Chinese brands like Honor 6x, even iPhone SE, if you do not pay attention to the screen size.


Samsung Well established when developing external The species of flagship devices like Galaxy S8, so its possibilities are not questioned. However, these innovations still have not reached the devices of the average price category of this company. Externally, Galaxy J7 reminds the Galaxy Note 2 tablet, not counting some sensors, and this unit has come out five years ago. The large metal inscription Samsung and the silver grid of the ears are well combined with silver buttons without backlighting and the frame around the Home button, inside which is not the fingerprint scanner. All this gives a smartphone outdated appearance, reminding about the times of plastic devices Samsung. This silver accents end, the rubberized plastic coating in the corners and the back is used.

Also behind is a lone horizontal metal strip of about 12 mm wide, inside of which the camera is located with a resolution of 8 megapixel and one LED flash. They do not protrude beyond the body. On the right side there is a metal lattice of the dynamics, also inside the metal strip. This unusual location allows you to not close the speaker with your hand when you hold the smartphone. Below on the right is a loudly closing power button, in this place it is easy to reach it. On the other side there is no less loud volume control, although it is slightly higher and to pull the finger to it when you hold the device in one hand. The device weighs 159 g, which gives him a sense of solidity. More Thin smartphones with large screens tormented to slip out of the hands, and here a thicker case with rounded corners provides improved grip.


Samsung decided to use LCD instead of the usual screens AMOLED of its own production. It is capable of in most cases to produce saturated and fairly accurate colors. The screen has a noticeable cold bluish tinge, which is most often observed in white and purple colors.

Oddly enough, the screen resolution is not even 1080p here, but only 1280 x 720 pixels and pixel density 267 PPI. Despite this, the detail is at a good level. An increase in the image in high-resolution photographs does not lead to grain or pixels. Meanwhile, there were such fears from the TFT panel. The screen is very bright, the maximum value is 628 threads and it is enough to install a brightness by 25%. There is no surrounding sensor here, and with it there is no automatic brightness adjustment. Instead, it is not proposed not the best outdoor mode, which increases the brightness of the screen for 15 minutes or comes, if the screen remains on.

Interface and Functionality

Together with the Samsung Galaxy S8 smartphone, a new interface of this was presented Manufacturer called Samsung Experience. The main purpose of this interface is simplicity and now this simple interface reached Galaxy J7. There is no large-scale support for gestures and flagship model sensors, so the functionality is simpler. Users will get an easy interface with a trimmed settings menu and meaningful search, device support, a safe Samsung folder and a more connected appearance. You can not turn on the gestures up and down to open the list of applications, as on S8, which again shows the simplified nature of this interface on this smartphone.

For most functions, SAMSUNG proprietary applications are responsible, including text correspondence, Internet and email. The quality here is at a good level, Messenger is simple and intuitive, like a web browser, not counting the support of gestures to transition back and forward, the mail client has a convenient location of the elements. The main problem of the mail client is the lack of linear viewing of notifications. For example, Gmail allows you to delete letters and respond to them through notifications, but Samsung makes it possible only to clear notifications or write an answer. Settings inside the client are not perfectly combined with system settings. Synchronization option SMS messages with an email account only in the application settings section, but not in the system settings, as in the case of other synchronization options.

Processor and Memory

The device operates on the SAMSUNG EXYNOS 7880 processor, this is an 8-nuclear chip with a clock frequency of 1.6 GHz. The same processor was used in Galaxy J7 2016 and in unlocked J7 2017. I would like to see the faster Exynos 7880 1.9 GHz processor with the ability to work with the UFS 2.0 storage, but simple buyers of inexpensive smartphones won't notice the difference. Samsung reaches good results even with an old processor. It is helped by 2 GB of RAM and 16 GB EMMC. There will be no rapid speeds, but there is no slowdown. Navigating the system and multitasking sometimes demonstrate small pauses, but in general everything works smoothly and responsive.

Like most medium-categories, this one can run games, but not the best way. In them you will see the real colors of the screen, which are not mediocre on the resolution of 720p. Sea and pixels are visible, more than with other use options. Many personnel will be missed and the games will slow down.


Supports communication standards Bluetooth 4.1, Wi-Fi 802.11 A / B / G / N / AC / R, four frequency bands, which allows you to work in most countries. No support NFC, and with it and payments Samsung Pay. If the South Korean company wants to make it widespread, it should include this system even in cheap smartphones. In the meantime, it will also have to buy more expensive Galaxy A7 to obtain payments and connections USB-C. There is no wireless recharging there, it is only available in flagships.


The rear chamber has a resolution of 8 megapixel and relatively large aperture F / 1.9. Samsung is known for the extensive features of the camera application and in Galaxy S8 it is one of the best. In Galaxy J7 there are no flagship options like a selective focus, slow motion or hyperlapse. There are more basic capabilities, such as HDR, night shooting mode and Pro mode.

Quality of photos is good. The color rendition is quite accurate, detailing sufficient with good lighting. There is a loss of orange color in landscaped shooting, there is also a sufficient level of depth. This can be attributed to the inclination of the images. Helps the use of HDR mode, but orange it will not return. Sometimes objects come out too sharp and detailing due to artifacts, but this happens infrequently.

HDR should be included in most cases to refund the parts and colors. However, there is a limit here, especially with weak lighting. In any case, HDR leads to an increase in the shooting time at least half a second, which should not be for the proper exposure. Sometimes HDR increases the shooting time for a second.

With weak lighting, the camera manifests itself in the best way. A relatively large aperture helps to increase the detail and in some situations instead increases the grain of the image. Due to the trend towards the overexposition, the level of detail in dark places increases, where, with proper exposure, the lens would not be collected sufficiently light. It does not improve the image quality, as overexposure blurs the image and erases small objects, such as leaves and branches. The inclusion of HDR, which does not automatically, solves this problem and brings another. Colors and separation between objects are returned, but sharpness is lost, with the result that the image begins to look drawn.

To consistently get high-quality photos, you need to use a professional shooting mode, especially with weak lighting. This is a full samsung set with ISO settings, white balance, brightness balance, etc. The ISO decline creates wonders for overexposure and sometimes helps to increase the detail. The problem does not disappear completely and nothing will help with a weak capture of light, but the result is better than automatically.

I would like to see automatic HDR and improvement in automatic shooting so that you can simply make and remove that most users need.


The front camera 5 MP offers a pair of useful features and provides Decent quality with good lighting. The decoration mode contains three sliders with snapchat filters for individuals. They are not cartoon, like in Snapchat, but allow you to change the skin shade, make a face thinner, increase your eyes, and all this on a scale from 0 to 8. On low settings, it allows you to get rid of skin deficiencies, on the maximum one can become similar to aliens. Wide-angle selfie allow you to fit more people in the frame. It will take a strong hand for shooting or photo will not work high quality.


The maximum video resolution is 1080p, the quality and color rendition are good. When moving, there are noticeable disadvantages. Fully absent image stabilization and visible shaking at the slightest uneven movement. Autofocus is also uneven, focusing only on a certain length and takes this time.

Call Quality

This parameter here is quite good. HD Voice is supported, although then there is a feeling of muted turbid sound, which most will not even notice, unless they do not switch to this smartphone with significantly better. Speakerphone loud, but it also has the same small problem with sound.

Autonomous work

Not that. The battery capacity of 3300 mAh allows you to reach the second day of work with moderate use, especially if you reduce the brightness. In tests with the screen on, the J7 lasted 12 and a half hours, which is impressive. Charging time is also quite long, 2 hours 22 minutes.


There is a temptation to classify this device as “for the seniors ” who are not chasing trendy shiny flagships who have enough solid devices for many years to come. The same price category and a little higher are tech-savvy people who see no reason to buy smartphones for 60 thousand rubles. As a result, the value of such models is constantly growing and will continue to grow. Many manufacturers, well-known and not so, offer their models at an average price.

If you don't care about screen size and want a cheap yet valuable Android smartphone, think again. iPhone SE has better call quality, faster and smoother performance, a better 4K camera, better materials and a fingerprint scanner. $80 more than the $240 J7 is the 16GB iPhone 6s.

If you're loyal to Android and want a screen over 5 inches, options are also available, like the Moto G5 Plus. It has a better camera and stabilized 4K video recording, fast charging, a fingerprint scanner, a nicer screen, and a $230 price tag. Externally, the device is also more attractive, but this is a matter of taste.

Nokia 6 for $230 has a stylish metal body, 16 MP camera, fingerprint scanner and NFC. There is also Honor 6X from Huawei. It's one of the best mid-range smartphones with some flagship features like dual cameras, 3 GB of memory with a fast processor, a fingerprint reader, solid performance and a price tag of $200-$250.

As a result, we can say that the choice of devices for $200-$300 is greater than ever.

Samsung Galaxy J7 for AT&T is a good device. The redesigned interface is lightweight and features proprietary Samsung apps that are both useful and intuitive. When navigating and launching applications, there are occasional hesitation, but more often everything happens quickly and smoothly. The screen is quite clear and colored, although its shortcomings strain vision. The camera isn't the highest quality for the price, struggling with exposure, focus and detail, but it's far from the worst and does the job.

Some of the competitors mentioned above are more attractive to technology enthusiasts, there are advantages for more casual users, but there are also disadvantages. So, protection from at least splashes would not hurt. Also, no one would turn down more flash memory or a better camera. Screen imperfections are also visible to anyone with eyes.

If you like Samsung's approach to Android and don't want to spend more than $300, the J7 2017 is the only choice. On the market as a whole, this is not the best smartphone in terms of price and quality.
