Samsung Galaxy J7 Review


The latest Samsung Galaxy J7 was launched in Europe just over a month ago, and since then, AT & T has begun to sell its 2017 Galaxy J7, with specifications and a style that’s much closer to the J7 V. for Verizon in March. In fact, the external appearance of the phone shows that it is the same phone but with slightly modified internal parts. The J7 has many variants, all in the middle range. This one seems to mix elements of the Verizon J7 V, which was released in March, and the Galaxy J7 2016, which was released last April. The new AT & T J7 2017 has a lot of competition without having a contract. This award and its configuration brings it to the larger specification 2016 J7 company, to the consistent and reliable G series from Motorola, and even to some Chinese brands that are firmly stated as the well-preserved 6X honor. Apart from the size of the screen, the iPhone SE also competes in this price range. So, this Mix-N-Match remix offers Samsung the talent and skills to win these highly competitive, unlockable and friendly AT & T middlemen

Design / connectivity

For many years, Samsung has been known to produce poor quality mobile phones and uninspired designs. All this changed with the Galaxy S6 and S6 Edge and was replaced by a sleek metal and glass design that left many surprises behind. Since the time of the Galaxy S5 voluminous and voluminous Samsung had turned his ugly duckling with the Galaxy S6 into a beautiful swan.

In fact, the design was so amazing that suddenly the iPhone 6 looked a bit flawed. Now you’ll wonder why I’m talking about the galaxy’s lighthouse in an article reviewing the J7.

Even though Samsung has come a long way in the development of its flagship products, this does not apply to low-end and midrange devices.

Some attempts were made by Samsung in the form of the metal-infused A-series and the inclusion of a metal frame and a brushed metal back on the Galaxy J5 and J7. However, considering the competition, which improves their game in terms of quality and design, the Samsung Galaxy J7 seems outdated and uninspired.

In the age of monohull metal smartphones with superb build quality, Samsung’s high quality no longer keeps up with the wave of their brand and takes the design and construction of mid-range devices seriously.

However, it should be noted that the device is quite slender at 7.8 mm, but weighs about 170 grams.

The smartphone has the volume buttons on the left, the power button on the right, the main microphone, the microUSB 2.0 port, and the headphone jack on the bottom, with the speaker, camera, and LED flashing. the back. The front has a physical start button, capacitive buttons for the back and current applications, the front camera and a LED flash.

However, since there is no fingerprint sensor, the smartphone can not be used for Android Pay. In this price range, most smartphones, including the Moto G4 Plus, are equipped with a fingerprint sensor, but they lack NFC, while the J7 is equipped with NFC technology, but no fingerprint sensor. Therefore, people looking for a smartphone compatible with Android Pay in this price range will find things incredibly frustrating.


Processor, battery and camera

The J7 runs on a Qualcomm Snapdragon 617 processor at a speed of 1.4 GHz and gets a solid score of 33,107 on AnTuTu, which evaluates the overall performance of the system. It’s much better than the Pen 2 with Snapdragon 410 (26,822) and the Galaxy J3 with the Exynos 3475 engine (17,284). Performance is smooth when it comes to launching apps and multitasking. I have noticed no delay, even when multiple applications are running in the background. With 2 GB of RAM, it is unlikely that the RAM usage limit will be reached. Premium games like Asphalt 8 and GTA San Andreas work with minimal control latency.

The duration of the battery is also good. The J7 recorded 6 hours and 21 minutes in our reduction test, in which we set the brightness of the screen to the maximum and transmitted the video in full screen via LTE. It’s almost the same as Pen 2 (6 hours, 6 minutes), though the smaller Galaxy J3 surpasses the two with an impressive 9 hours and 27 minutes. In any case, use during the day is no problem, and you can always change the removable battery.

Interface and functionality

With the launch of the Galaxy S8 came the latest version of Samsung’s Samsung taste, simply called, Samsung Experience. Its purpose was simplicity, and we were impressed with the UI command that was executed then, as we are now, because it finds its way into J7. Of course, the J7 does not have all the gestures or sensors that come with the S8, so you will not find any action or Bixby signals on board (much like the S8 now – SIMPLY RIDGE SAMSUNG, MATE USA, BY FAVOR). But what you’ll find is the lightest user interface, the smallest settings menu with its comprehensive search function, device maintenance, the secure file from Samsung and the most complete design language. consistently that we are happy at this time and now. For some reason, you can not allow a gesture to slide up or down to open the application tray as in S8. So there are few peculiarities like the ones you can miss, but general experience is usually the same.

Specifically, we’ve found that the option to sync SMS messages with your email account is available only in the configuration of the email application and not in the Accounts section of the phone’s main configuration. other synchronization options. It is a small detail, but still a mistake. We assume that there has been at least a small error in the entire cleaning that you made in the configuration menu. In the end, however, it was the lack of online options that sent us back to Gmail earlier than expected. If every e-mail you receive always contains important information that you need to keep or answer, you should not lose the online distance, but you will certainly do so.

Samsung Galaxy J7 (2017) key test results

The quality of the construction and the materials are of outstanding quality, we appreciate the IP54 rating. Antenna bands are not for everyone a cup of tea.
The high-quality Super AMOLED display has a very good maximum brightness and infinite contrast and can set striking or sharp colors to your liking. The readability of the sunlight is excellent.
Battery life is excellent, the phone’s resilience is 108 hours, and excellent results are found in all our individual tests.
We are pleased to see the new Samsung UX in J7 (2017). It looks almost the same as the one that works on the Galaxy S8.
The Exynos 7870 processor is powerful enough to handle all daily tasks. The GPU, on the other hand, is not only outdated but also weak and responsible for unsatisfactory gaming performance. In absolute terms, it’s a mid-range SoC that’s not very game-friendly. Interestingly, the Game Launcher does not have the ability to change the resolution of the game, which would have improved performance.
Very good audio output via amplifier and headphones. The speaker is surprisingly loud and has got another brand “Very Good” in our tests.
The picture quality of the main camera is good, but not spectacular. The detail is sufficient and the noise is quite low, but the dynamic range is pretty bad, the colors are a little softened to our liking and there is sweetness in the corners.
The quality of 1080p videos is very good, as is the audio that accompanies them.
The 13MP selfie camera has a solid performance. However, there are some minor development issues, such as the Galaxy A5 (2017) and A7 (2017). The front light works well and could bring some added value to the right user.
