About this phone and collected the flaws and problems of the 2017 Samsung Galaxy J7 (SM-J730F) phone in this article. Previously, I did a review of phones, and. In my opinion, users had too many complaints about S and A series phones, so it was interesting to find out how things are with the quality and bugs of the J series.

SOFTWARE

- in the calendar from Samsung and the Google calendar, event notifications do not work adequately. If there are no events in the calendar for several days, then it falls asleep. Installing Samsung Focus does not help. As a crutch, the creation of daily events in the calendar helps. Also, the problem is solved by installing third-party programs. For example, aCalendar, Calendar Notifications, Business Calendar 2. Having installed, for example, aCalendar, you need to enable synchronization with a calendar from Samsung or Google in its settings. Also, don't forget to add aCalendar to the power saving exclusion list, and the problem with notifications will disappear.
- user complaints that the phone, which has so little memory, has heavy programs MS Word, Excel, PowerPoint, programs from Samsung that cannot be removed by regular means.
- the problem with lack of memory can be solved by enabling the permission to transfer user-installed applications to the SD card in the developer menu. But, unfortunately, not everything works perfectly here. After each update of applications, they are installed again in the phone's memory and need to be transferred to the memory card again. If you have a lot of applications, and they are regularly updated, then the transfer procedure can quickly get boring. In addition, complaints are not uncommon that applications do not work correctly with a memory card. Something disappears, does not start. It is clear that this is not the fault of the phone, but of memory cards of unknown quality, but the owner of the phone has an additional risk that something will stop working.
- a small amount of memory requires increased attention to the phone. You need to clear the cache of instant messengers and other programs. Software updates downloaded by the phone also actively consume memory.
- files are duplicated in the built-in gallery. For example, you have a photo and send it via Viber and Skype. After that, the photo will be duplicated in the gallery 3 times. You need to install third-party software that will search for and delete duplicated files.
- I would also like to say a few words about software updates. After reading discussions on the forums for several months, one gets the impression that with each new software update, people were more and more afraid to install them. Corrections are no longer expected, but they are afraid that something will be broken. For example, after the February update, Samsung corrected something in the sensitivity of the wheelbarrow, and people on whose phones protective glasses were installed began to have problems with the screen. The touch did not always work, the top curtain did not leave. Someone was helped by the calibration of the wheelbarrow, someone had to remove the protective glasses. It is also necessary to note the work of Samsung technical support, tk. it is also often discussed. Unfortunately, very often people receive unsubscribes to their questions with a universal advice to reset the phone software to factory settings.

NETWORK, COMMUNICATIONS

- in general, there are few comments on the operation of the phone. Often problems are solved by simply replacing the SIM card. It is also worth noting that, despite the lack of a second microphone for noise reduction, there are no complaints about the sound quality.
- one of the most frequently encountered comments is the lack of support for the Troika card in NFC. NFC does not support Troika, since Samsung does not use Mifare Classic technology in this phone model.
- there are rare comments on the work of WIFI. The phone does not automatically connect to a network that it already knows. Disabling and enabling WIFI helps.
- although rare, users have questions about the operation of Samsung Pay. Everything doesn't always work perfectly. Questions are discussed, how best to put the phone to the terminal, where the NFC antenna is located, etc. If there are problems, then pay attention to how Samsung Pay turns NFC on and off.

FRAME

- when buying, pay attention to the weight and dimensions of the phone. The phone is not light, it weighs 181 grams. Also note that when installing a case or bumper, the size of the phone will increase. Dimensions and weight I would not call disadvantages, it's just a moment worth paying attention to.
- it is advisable to buy a cover or bumper. body is slippery. Although, of course, I also met more slippery phone models.
- Keys are not backlit.
- no event indicator light. Not very convenient, for example, when you can’t see if charging is still going on or not (as a solution, you can use a non-native cable with a charging indicator).
- unusual location of the volume buttons on the left side of the case.

SCREEN

- When Always On Display is enabled, the entire screen of the phone glows slightly. This is noticeable if you unlock the phone in the dark and then lock it again. If the phone is locked in a bright place, and then, for example, turn off the light, then the screen will glow in about 30 seconds. The glow, although weak, is noticeable at night.
- Always On Display does not turn off when you put your phone in your bag or pocket. The AOD brightness takes a long time to adjust to the lighting. For example, you take your phone out of your pocket and you have to wait 15-20 seconds for the AOD to glow bright enough to be able to make out something.
- there are complaints about the work of auto-brightness. You have to wait 5-7 seconds for the screen to react to changes in lighting. Complaints mainly began to appear after users installed software updates in February.
- after the software update in February, there were also a lot of complaints about the operation of the wheelbarrow. It didn't always work. Basically, the problem was solved by peeling off protective glasses. Someone was helped by resetting the software to factory settings, someone was helped by the calibration of the wheelbarrow. To calibrate in the phone, you need to enter the code * # 2663 # and press the TSP FW Update and Touch key GW Update buttons in turn.
- not often, but there are complaints about the fragility of the display. Not screen glass, namely the display. The glass may remain intact as a result of a fall, but dark spots or streaks may appear on the inside.

IRON

- today there is not enough memory built into the phone. Approximately 10 GB of free memory is available to the user.
- not often, but there are complaints about the disappearing sound from the speaker. Reboot does not help in this case. You need to turn off the phone and wait a few minutes.
- there are complaints about the operation of the fingerprint scanner. Over time, the sensor does not start to work the first time. Helps to overwrite fingerprints. When overwriting, users recommend pressing your finger firmly against the scanner.

CAMERA

– the cameras are quite good, considering the price category and positioning of this model. On gsmarena you can compare the photo quality of different phone models. It should be borne in mind that the cameras do not have optical stabilization, and you should not particularly rely on aperture of 1.7.
- users most often have questions about the autofocus of the main camera. In poor lighting, the camera can focus for a long time, in good lighting it is not always clear the moment when the autofocus worked.

BATTERY

The phone does not have fast charging. The phone charges in 2.5-3 hours.
- particularly frugal users disable AOD. This feature consumes approximately 1% of the charge in an hour and a half. If AOD is always on, then it consumes approximately 16% of the charge per day. I think this is a normal indicator. It's just that there are reviews in which people write that AOD is dropping the battery. I do not think so. I specifically wrote about the power consumption of AOD separately, because. This feature of the phone attracts many people and is a significant factor when choosing a smartphone.

CONCLUSION

It is safe to say that the J7 is a much more interesting phone in terms of price / quality ratio than the Samsung S and A series. The phone has very few drawbacks. The only thing that can alert you is the display, which is sensitive to falls. Its replacement in the official service costs 6-7 thousand rubles. Otherwise, the phone does not have any critical bugs and marriage. If you're looking for a relatively inexpensive phone, then the 2017 Samsung Galaxy J7 is worth considering as a candidate.

The Samsung Galaxy J7 is an entry-level smartphone for users who don't need fancy hardware. In the line of the company, the device occupies a starting position, but judging by the cost, it can be regarded as a “strong middling”. This is a device with a good, high-quality display, having on board everything you need for high-quality and hassle-free daily use.

Design and management

Samsung Galaxy J7 has four body colors: black, blue, gold and pink. A smartphone in a black case looks a little more advantageous, more solid. Blue and gold look interesting, but somewhat catchy, like pink. The case is made of durable metal, without gaps and backlashes of individual parts. During use, the coating applied to the body is not wiped. At the back there are inserts for antennas, they are made of plastic.

There is a button on the front for owner fingerprint recognition. The fingerprint sensor works quickly, no false positives were noticed. The front location of the sensor turned out to be a very convenient solution, you have to reach for it from behind, but here it is always available. Thanks to its compact size, the phone fits perfectly in the palm of your hand. Relatively small size and weight allow you to carry the device in your jeans or trousers pocket.

The front also houses the camera, flash, and ambient light sensor. Unfortunately, there is no backlighting for virtual keys. The volume and power buttons are placed on separate faces so that the owner does not confuse them when pressed blindly. Above the power button is a speaker. The solution is unusual, but it allows you to maintain internal ergonomics. Charging and headphone jack are on the bottom. The overall impression of the design and controls of the Samsung Galaxy J7 is quite pleasant.

Screen features

The Samsung Galaxy J7 display is made according to proprietary SuperAMOLED technology. Compared to last year's revision, the screen has improved markedly. Colors are brighter and more saturated. In addition, they can now be manually adjusted up to 350 nits. If you select automatic mode, say, "outdoors", then the indicators will be increased to 550 nits.

Important! A big plus of this model is its excellent readability in natural light. In the sun, the screen practically does not fade.

The color rendition has become more natural, the gamma is bright, voluminous. Particularly to be commended manual white balance adjustment. If you don’t want to fiddle with the settings, then you can set the automatic mode, there are several of them in the settings.

The Samsung Galaxy J7 has a screen size of 5.5 inches. The resolution is an FHD matrix, and a larger gadget is not required. If we compare the device with its main competitors in 2016-2017, its significant superiority will become obvious.

This budget model has Always On Display option. A pleasant surprise, given that it is more typical for flagships and some smartphones of the company's mid-range price segment. The implementation of the “non-switchable display” is not without flaws; rather, this is the point when one should rejoice at its presence. Immediately striking is the severely curtailed ability to select information that will be displayed on the screen. In this case, it all comes down to showing the time, a message notification, and a few app icons. The clear advantage is low power consumption in this display mode.

In general, the display of the Galaxy J7 smartphone is its clear advantage, which distinguishes it from other gadgets in this price category.

Memory and performance

The specifications of the Samsung Galaxy J7 2017 show good performance figures. Three gigabytes of RAM allows you to keep several applications running at once. The amount of internal memory is quite small by today's standards, but the available 16 gigabytes is easy expand with a memory card. The device supports flash drives up to 256 gigabytes.

The processor of the device remained the same as in the last year's version. This decision was made because the architecture proved to be excellent. There is enough capacity for everything you need. Besides, chipset not overheating, and this is a very important indicator for an entry-level processor.

On a note! In Antutu, the smartphone scores 47,000 points. Not a bad result for an inexpensive device.

The power of the Samsung Galaxy G 7 is enough for undemanding games and most applications. It is possible to play the novelties of the gaming industry, but they will not work at the maximum graphics settings. However, the device was not positioned as a gaming device.

Operating system

The Samsung Galaxy J7 2017 phone runs on the Android version 7.1 operating system. At the time of the release of the Nougat model, it was the current OS for most new products. Of course, the interface has undergone some refinement by Samsung. This is not quite pure Android, but not a full-fledged graphical shell either. Unlike the "blank" OS here there are several software improvements, which are inherent in many smartphones of the middle and older price categories. An example is the AoD mentioned above.

Important! There is full hardware and software support for two SIM cards, which is very convenient. Users who are used to switching between accounts to use different numbers will be pleasantly surprised by improved synchronization.

Most of the functions of the Android OS have not been subjected to major changes. The user has a phone with a simple, understandable and very convenient system in his hands. And, importantly, with a minimum of pre-installed applications.

Communication and sound quality

Since Samsung Galaxy J7 smartphones are a budget solution, you should definitely not expect exclusive sound from them. The available equalizer is capable of handling different bitrates, depending on the format and quality being played. The settings provide a minimum level of comfort, but lovers of high-quality sound will definitely pass by this device.

As for the level of signal reception, everything here is at a decent level. When speaking, the user perfectly hears his interlocutor. The signal level rarely drops to the lowest level. When switching to speakerphone, the speaker may slightly distort the voice.

Communication with navigation satellites is quite fast. The level of error is low, so the phone is quite can be used instead of the navigator. The transmission of Internet traffic is not satisfactory. Measurements show that the gadget provides excellent throughput in third-generation networks.

Battery and autonomy

Smartphone Samsung Galaxy J7 2017 is equipped with a battery with a capacity of 3600 mAh. This is a little more than last year's version. On the other hand, the screen diagonal has grown. However, the increase in the diagonal is offset by a change in the manufacturing technology of the matrix itself. SuperAMOLED has a slightly lower power consumption.

At the maximum brightness level, the smartphone is capable of play video for nine hours. Of course, if all communication modules are active at the same time, the operating time will be significantly reduced. However, user feedback speaks of improved autonomy compared to last year's revision. On average, this figure increased by 20%.

There is no fast charging function, but there are energy-saving modes. They allow you to significantly increase the autonomy. On average, with a moderate load, the phone lives for about a day or a little more.

Camera Specifications

The review of the Samsung Galaxy J7 should be completed with the parameters of the photomodule. The main camera has a resolution of 13 megapixels. This is quite enough to create good pictures in natural light. In a dark room, using a flash, most likely, it will not be possible to achieve high-quality shooting. However, in comparison with last year's model, progress, again, is evident. Manual settings now allow set white balance. There are a few more options for debugging at your own discretion.

The front camera also increased the resolution, now it has 13 megapixels versus 5 for the previous model. This is quite enough to create a high-quality self-portrait. Built-in set of filters and high-quality flash will help all selfie lovers to take a lot of interesting and bright pictures.

Conclusion

In its class, the device feels quite confident. It costs a little more than Chinese devices, but outperforms them in quality. At the time of release, the model gained great popularity and remained in high demand for a long time. Smartphone price at the time of sales was from 15 to 20 tr. depending on the store. There are no differences in technical characteristics within the model, the user can only choose the color.

The Samsung Galaxy J7 is an example of style meeting function. Crafted with attention to detail, the Galaxy J7 features an amazingly sleek metal body. The absence of a camera bump provides a more comfortable feel of the phone in the hand. The smartphone has a Full HD 5.5" screen and a 2.5D protective glass guarantees greater durability.

Share the events of your life as you see them

Deciding on the type of device (phone or smartphone?) is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to stop the choice on the phone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly less than that of a regular phone.

In 2015, Samsung decided not to multiply the number of smartphone series, introducing confusion, but to regularly update existing lines. At the end of the year, the company announced an update to the A and J lines, releasing mid-range devices before the new year. In April 2016, the turn came to J7. Several variations of the device were released, but the Samsung Galaxy J7 SM-J710F (2016) is presented on the market of Russia, Ukraine and some other European countries.

Model J710F is a simplified modification of J7 2016. Its price is about $280. According to the characteristics, the smartphone is slightly behind the J7108 and J7109 sold in Asia. The differences lie in a different screen, processor and memory sizes. The camera remained unchanged (which pleases). The review of the Samsung Galaxy J7 SM-J710F (2016) is designed to find out whether there is a big difference between the versions in practice, whether the younger one is worthy of attention.

Specifications Samsung Galaxy J7 SM-J710F (2016)

The smartphone received characteristics that are typical for a mid-range device from Samsung. But they may not seem convincing enough against the background of Chinese competitors 1.5 times cheaper.

Design, body materials, dimensions and weight

In terms of design, the Galaxy J7 SM-J710F is a typical Samsung, the differences from its predecessor are minimal. Of the innovations, it is worth noting the metal base of the case. Regardless of the color of the device (it can be white, black or gold), the frame surrounds the display with a silver frame. Removable plastic cover. The dimensions of the smartphone are 15.17 x 7.6 cm, thickness - 7.8 mm, weight - 170 grams (even 1 year less than its predecessor).

The front panel is glass.

On top of it there is a speaker slot, two windows for light and proximity sensors, a camera and a flash.

Below - the traditional mechanical button "home" and two touch, on the sides of it.

The camera is located at the back (its lens is framed by a silver metal border), symmetrically, on the sides of it, there is a metal speaker mesh and a flash.

The metal frame is separated from the top and bottom by plastic strips-inserts. The top end contains nothing (except for these inserts).
At the bottom there is a microUSB port, a microphone hole and a headset jack.
The volume control buttons are on the right.
On the left side is only the power button.

CPU

The Galaxy J7 SM-J710F is based on the Exynos Octa 7870 chipset. It consists of 8 Cortex A53 cores operating at up to 1.6 GHz. Despite the higher model number, the chipset is weaker than the Exynos 7420 found in the S6. Its closest competitor is MediaTek's Helio X10. The test results of these chips in AnTuTu are similar - about 48 thousand points. True, the Samsung chip was created using a more subtle process technology, so it should be a little more economical.

The Mali T830 accelerator is responsible for the graphics, hence the performance difference with the flagship 7420 chipset. Almost all games will run on it at maximum settings, and only some may not produce enough high FPS. But the fact that the T830 MP2 is 4 times weaker than the T760 MP8 remains a fact.

Memory

The amount of RAM Galaxy J7 SM-J710F is 2 GB, it is recruited with DDR3LP chips. At the start, the system consumes a little over a gigabyte of RAM, the remaining space is enough for multitasking. 3 - 6 programs in the background are kept without problems, a heavy game can also be quickly collapsed and deployed. The difference in speed with the more expensive model J7108 (which has 3 GB), if any, is minimal.

Nearly 11 GB is allocated for user data, out of 16 in total. A slot for a memory card is available, it is separate. Modules up to 128 GB are supported.

Battery

The battery of the smartphone is removable, its capacity is 3300 mAh. As expected, due to the energy-efficient chipset (with a 14 nm process technology), the autonomy of the smartphone is at its best. Yes, and lowering the resolution had a positive effect on the time of work. Unlike TFT, the consumption of AMOLED matrices depends not only on the diagonal, but also on the resolution, since each pixel glows independently.

You can watch videos from 12 (light colors) to 15 hours (with reduced backlight and the predominance of dark shades). With moderate use, the smartphone quietly lasts 2 days. In games, the Galaxy J7 SM-J710F will sit down in about 7 hours. For a 3300 mAh battery, these figures seem huge.

Charging is normal, 1.5 A, with a European plug. From it, the process of replenishing the tank lasts a little more than 2 hours. It makes no sense to change the memory to a more powerful one: currents greater than 1.5 A are not allowed by the charge controller to the battery, the speed will remain the same.

cameras

The main camera Galaxy J7 SM-J710F is built on a 13-megapixel matrix of its own production. It supports contrast (phase) autofocus, but has an improved aperture of f/1.9. The pixel size is standard, 1.1 microns. Surprisingly, for its characteristics, the camera in the smartphone is very good. During the day, the pictures are excellent, they can be safely compared with the photos from the flagships. In the evening, too, everything is fine, although the noise still appears. Focus works correctly in most cases.

Sample pictures:

Pictures in HDR mode:

Front camera Galaxy J7 SM-J710F - 5 MP. The device is positioned as a selfie device, so it is equipped with a front flash. There is little sense from it, but in the dark there is a small gain from the backlight. The front camera has no light focusing.

Selfie:

Video is recorded in 1080p resolution at 30 FPS.

Screen

The Galaxy J7 SM-J710F has a 5.5-inch Super AMOLED display. Its resolution in this model is 1280x720 pixels (the version for Asia is equipped with a FullHD screen). The pixel density is 267 per inch. In terms of economy, the HD display wins, but there are doubts about the quality. However, the smartphone's screen is very bright, color reproduction is close to natural, and viewing angles are good.

There is only one nuance - pixels. If they are not visible at 35-40 cm from the eyes (from the word at all), then the owners of the “eagle eye” can still notice the “mesh”. Interestingly, this effect is not so pronounced in IPS (it seems that a matrix with PenTile is used here). In principle, it can be neglected (many will not notice anything at all), but this moment alone does not allow us to evaluate the matrix as much as possible.

Communications

There is a version of the smartphone with 1 SIM, but the Galaxy J7 SM-J710F has two. Both slots are designed for Micro cards. They are separate, located under the cover near the battery. All European networks from GSM to LTE are supported. Wi-Fi is designed to work only with networks with a frequency of 2.4 GHz, this is a small but minus. Bluetooth - version 4.2, with support for stereo sound transmission, but in a compressed form.

Navigation works with GPS and GLONASS satellites. In the Asian version, BDS is also announced, but in Eastern Europe they are either not caught on this smartphone, or (more likely) the Exynos chip is not at all “friendly” with Chinese satellites. There is also NFC on board, which works fully (and not just for payment, like Apple).

Sound

The smartphone does not have a dedicated audio processor. There is only one speaker, it is located at the back. The sound from it is distinguished by high volume, purity. Of course, there is a deficit with low frequencies, but this is not a tweeter. The middle range is played quite well. In the headset, the sound is average, it is enough for comfortable listening to music in normal "ears". There is a radio receiver, you can record programs from it.

Operating system

The smartphone is running Android 6. The TouchWiz graphical shell is present, but it is quite balanced and not as overloaded as in the old days. Therefore, there is no “zhora” of RAM, everything “flies”. The OS “shutter” has been worked out better than in stock Android, it is convenient to use it.

Features and differences of Samsung Galaxy J7 SM-J710F (2016) from its predecessor

The device has become half a millimeter shorter and 2 mm narrower, the weight has decreased by 1 gram. The J7 2015 also used a slower (though also eight-core) Exynos 7580 processor.
