Samsung continues to expand the J line, which includes the most affordable smartphones of the Korean manufacturer. More recently, this family has replenished with a device called the Galaxy J3 Pro, this is an improved version of the regular model. The freshly baked smartphone has acquired a number of improvements, including a changed appearance in accordance with the new design concept of the brand’s budget devices, a different processor and an increased amount of memory. Get to know this device closer.
Design, materials and display Samsung Galaxy J3 Pro
The smartphone, as already mentioned, outwardly transformed, so you can not confuse it with the Galaxy J3 model. The fresh device looks much more solid than its predecessor. When you look at the new product, the feeling that the device is in metal is still in place, however, this is not so. This budget employee is entirely clad in a plastic case, more precisely, in polycarbonate with an imitation of premium material. Like the previous model, this smartphone is very convenient to hold, since the diagonal of the display is small, and the edges are rounded. Buyers are provided with two types of color design - golden and silver. The size and weight of the changes have not practically undergone. So, the dimensions of the Galaxy J3 Pro do not exceed 142.2 × 71.3 × 8 mm, while the weight is 139 grams.
The location of the various elements on the case remains the same. The front panel is covered with glass, under which there is a display, occupying 68 percent of the surface. Above the screen are the front camera peephole, earpiece, sensors and the manufacturer’s logo. A central mechanical key, traditional for Samsung products, is placed under it, and on the sides of it are touch buttons “Back” and “Menu”. On the right edge there is only a power button, and on the left only a solid volume rocker. A microUSB v2.0 connector and a microphone are placed on the lower end. At the top edge, a 3.5 mm headset output found its place. The back of the smartphone has a nice texture, here the main camera lens, LED backlight and a multimedia speaker are installed. The photomodule, which is important, now does not protrude above the surface.
Despite the positioning of the smartphone, it is equipped with a very high-quality screen. It was based on the SuperAMOLED matrix with good viewing angles, contrast and brightness level. Pixelization is almost imperceptible, since a resolution of 1280 × 720 pixels is used. This, of course, is not Full HD, but this is more than enough for reading and watching videos with comfort. By the way, the pixel density here is 294 ppi. The diagonal of the display is 5 inches.
Characteristics Samsung Galaxy J3 Pro
And now we have come to the most interesting, since when choosing an inexpensive smartphone, most people turn their attention, first of all, to its technical component. Galaxy J3 Pro received controversial hardware. Yes, the Snapdragon 410 64-bit chipset installed here is better than in the regular version of this model, but it is already rather weak by modern standards. This processor contains four cores of 1.2 GHz; in conjunction with it is the Adreno 306 module.
The filling of the device is not impressive, but the power reserve is enough for simple tasks. RAM the manufacturer brought up to 2 GB, and the storage increased to 16 GB, which is very good for a state employee. The device has a separate slot for a microSD card, so the storage can be expanded up to 256 GB. Also pleasing is the presence of a wide range of wireless interfaces, which is characteristic of more smartphones of a higher class. The equipment includes not only Wi-Fi and Bluetooth 4.1 standards, but also NFC to pay for purchases. GPS and GLONASS modules will not let you get lost. A version with two slots for microSIM cards will be available. 4G frequencies are supported. For autonomy in this gadget, a removable battery with a resource of 2600 mAh is responsible. Considering the not very powerful hardware platform and low screen resolution, one can hope for a good working time on a single charge. Functions "OSes" assigned to the platform Android 5.1 Lollipop, there is a shell.
Special attention should be paid to the photographic capabilities of the new product, since their level is quite good for a smartphone belonging to the budget segment. The rear camera is equipped with an 8 megapixel sensor with aperture of f / 2.2, there is a bright LED flash and good-quality autofocus. It supports recording videos in 1080p. Frontalka is endowed with a resolution of 5 megapixels and an aperture of f / 2.2.
Conclusion
A smartphone, of course, is able to compete for a place in the sun, despite the average characteristics. Big advantage Samsung Galaxy J3 Pro is a price tag that is within $ 150. For such a price, the device can be a very attractive option for budget buyers, because the design here is quite good, like the camera. But if you put higher demands on the device in terms of performance, you should pay attention to more expensive solutions.Koreans recently pleased with another inexpensive new product, introducing samsung smartphone Galaxy J3 Pro. It differs from the original model by a faster processor and a large amount of memory.
The official presentation of the device was held on June 6 in China, in the very near future Samsung representatives promise to open a pre-order for a new model, and soon residents of other countries will be able to buy the Galaxy J3 Pro. An inexpensive, but high-quality and powerful enough smartphone for its class has good chances not only in the Celestial Empire, but also in other countries of the world.
It is worth noting that the Samsung Galaxy J3 Pro is far from the first smartphone of the Korean giant, which starts in China (model number J3119). As we can see, despite the Chinese electronics manufacturers, Samsung products are successfully sold on the local market.
The recent announcement of other new products - this also confirms. And now J3 Pro has been added to them. Moreover, unlike the first ones, the novelty should appear in other countries in the very near future.
Galaxy J3 Pro Review
As we said above, in comparison with the basic version of the Samsung Galaxy J3, its “professional” version has become faster and “more voluminous" (meaning not the dimensions, but the amount of internal memory). Two color options are currently available: white-golden and black-silver.
Specifications J3 Pro
Here we can say the following. New Galaxy J3 Pro is a typical “budget”, about any outstanding features we are not talking for a completely understandable reason. However, it is a well-balanced and quality product. Thanks to this, he can successfully compete even in the Chinese market with countless Chinese crafts based on cheap and slow MediaTek chips.
Affordable Odnoklassniki Samsung Galaxy J3 Pro
Moreover, if you compare the Samsung Galaxy J3 Pro with flagships like the Galaxy S7, then the “state employee” even has its own advantages. For example, it is available both in versions with one SIM-card, and with two - Duos, but the slot for the memory card is not combined with the second card of the mobile operator, but a separate one.
The Galaxy J3 Pro also has a removable battery with a capacity of 2 650 mAh. This is more than last year flagship Galaxy S6, while the battery can be easily replaced on occasion. When the Chinese stamp their inexpensive “iPhone killers,” copying almost everything around Apple, they often forget that buyers of budget devices have completely different requests.
In general, thanks to a fairly capacious battery and a “quiet” processor, the Samsung Galaxy J3 Pro is simply ideal for listening to music and watching movies on the go. Compared to the same Galaxy S6, it will need to be recharged much less frequently.
In addition, the novelty supports 4G LTE, which not every cheap Chinese smartphone can boast of. There is also support for CDMA / CDMA 2000, though only for China (Galaxy J3 Pro J3119).

Externally, the Samsung Galaxy J3 Pro looks very stylish compared to the previous plastic “remnants” of the Korean company: there is a high-quality metal case with rounded corners, the form factor of a classic smartphone with a screen diagonal of 5 inches, and the main camera lens hardly protrudes, which can not be said. last year’s flagship Galaxy Note 5 (though Note 6 seems to be).
