Samsung Galaxy J7 review, accurate color and excellent sunlight clarity


The jungle of smartphones can be confusing, but the interpretation of the Samsung Galaxy J7 is very easy: J is “affordable price” and 7 is “big screen.” This is a lite version of the Galaxy A7 that offers semi-advanced features, but is limited to the midrange. Another way to look at it is as the E7 Plus.

The eye-catching features start with a 5.5-inch Super AMOLED screen (Samsung’s latest devices all have accurate color and excellent sunlight clarity.) There is also a 64-bit eight-core processor, one with a dedicated LED flash and one master The flash’s self-timer camera has a wide f / 1.9 aperture and professional mode camera.

The Galaxy J7 is one of those phones that care more about the screen size than its resolution, so it can reach 720p. The difference in the Galaxy A7 1080p screen is largely cosmetic, but the actual difference is very large – the application and web space on the A7 has increased by 20%.

Samsung Galaxy J7 Camera

The main camera is a 13 megapixel unit – this is a very standard choice for the IF – but the f / 1.9 aperture boosts it above average and will make a difference in low light scenes. The J7 is equipped with a low-light self-timer device with a dedicated LED flash to help with a 5 megapixel front lens.

Galaxy J7 is a dual-card phone, Samsung does not intend to use a single SIM card. If you ask us that there is no huge loss, unlike the A series, which has two SIM cards and a separate slot for microSD. Fast LTE data can be used on any card, making J7 suitable for travel or getting the most out of both data plans.

The Galaxy J7 comes with one of two different chipset models – Snapdragon 615 in some regions and Exynos 7580 in other regions. Both versions run Android 5.1 Lollipop on 1.5GB RAM (a bit compact), but Exynos has a CPU clock advantage. We’ll also look at the performance of different GPUs, both of which support OpenGL ES 3.1, so they’re ready for the upcoming new game.The Samsung Galaxy J7 will lose to the Galaxy A7 in a beauty pageant, but after the novelty disappears, the A7 will have a battle. Ok, it’s time to kick the Galaxy J7 out of the nest and see how good it is.

Unboxing Galaxy J7

The Galaxy A series is available in a cyan box, while the J series is in an orange box. This is a nice color coded with alpha code. The contents of the box are quite modest: microUSB cable, 5V 1.55A charger and integrated headphones.

The charger is not powerful enough for fast charging, but it is the same as the expensive A-series. The headset is obviously cheaper, it has only one button, and the simple earbuds are compared to the in-ear headphones of the A-series phones.

Hardware overview

The Samsung Galaxy J7 measures 152.2 x 78.7 x 7.5 mm (some versions are 7.9 mm) and is 1.2 mm (1.6 mm) thicker than the A7. It weighs 171 grams and weighs 171 grams. All of this gives it a greater feel, and the all-plastic look gives up its lower position in the pecking order.

Samsung has been strengthening its design games and using the latest advanced equipment to reach what most people call “pretty”. However, Galaxy J7 belongs to the previous era, a preference for the appearance of practicality. Ordinary design makes it a face in the crowd – is it J7? E7? Is some kind of Note Neo possible? What is grand? J7 does not pursue individuality, but is content to help the Galaxy series consolidate the mid-range rankings.

The hardware does have some outstanding features that make the smartphone the equivalent of a sleeper car – you won’t think too much on the parking lights until it drives away with sharp tires. Well, for the Cortex-A53 core and 13 megapixel camera, it only provides the right amount of screams, but you understand – the Galaxy J7 behaves better than it looks, as opposed to the flame decal.

On the bright side, Samsung did not make any major changes to the formula. This will allow the old Galaxys to be upgraded seamlessly, and the newcomers will adjust quickly.

The side and back of the phone are smooth and round, so nothing is poked into your hand when you hold the phone. After handling the slender Galaxy A8, the J7 is heavier than the thickness, but it feels a bit rough. 7.5 mm is still very good, but please note that some versions of the phone are slightly thicker (7.9 mm).

The rear panel is made of matte plastic for good grip. This is not the best feel we have ever experienced, but it can easily eliminate fingerprints. It has white, black and gold paintjob to choose from. The top and bottom of the phone are recessed, so the four corners rise slightly. This gives your finger extra grip when you take a photo with your phone horizontally. Otherwise the smooth chrome finish may be very smooth.


The Samsung Galaxy J7 is equipped with a large Super AMOLED display. In recent years, these are known for their precise color, excellent sunlight clarity and outstanding quality, although this special 5.5-inch screen has only 720p resolution.

From a practical point of view, 267ppi is enough, even for small and thin types, the text is still legible. This helps this to be an RGB type matrix instead of a PenTile. Most of the time you may not notice the slight serrations on the diagonals and curves, although you will find the difference.

The color is very accurate, you can choose basic, AMOLED photo and AMOLED video mode. We found that Basic provides the most accurate results, although many people prefer the other two modes – they combine saturation enhancement with enhanced contrast, which makes any image popular.

The angle of view is very good, but you can see the typical blue/green tone of extreme angles.

In general use, the display is darker than the best Super AMOLED, but matches the expensive Galaxy A8. The Galaxy J7 screen manages about 360nits in normal mode, but outside you can boost it to a more impressive 500nits in a short time (it will automatically turn off after a while to preserve the screen and battery.

User interface: familiar TouchWiz, no split screen

The Samsung Galaxy J7 comes with the latest version of Android 5.1.1 Lollipop and TouchWiz. The software is very similar to the high-end Galaxy A8 we recently evaluated, except that some advanced features have been removed (some are not so good).

The lock screen follows Android trends, including notification lists and some shortcuts – dialers and cameras. As with the Galaxy S6, you can quickly launch the camera by double-clicking the Home button.

The added weather information on the lock screen may not be standard Android, but it is useful enough.

Unlike the new A8, the Galaxy J7 lacks a fingerprint reader, so you can use the traditional locking methods – swipe, mode, PIN and password. Even if the dedicated mode can be set to use only passwords, there is no dedicated mode.

  1. Thanks for your helpful post. In recent times, I have come to understand that the actual symptoms of mesothelioma cancer are caused by the particular build up of fluid between your lining in the lung and the torso cavity. The ailment may start inside the chest location and spread to other limbs. Other symptoms of pleural mesothelioma include fat reduction, severe breathing in trouble, fever, difficulty eating, and irritation of the neck and face areas. It must be noted that some people existing with the disease never experience virtually any serious signs at all.
