    Today, the smartphone market is a whole world where everyone can find everything they want. There are also top-end flagships that have a price higher than the average person earns in six months, and there are generally budget solutions that are not intended for anything other than calls. There are also a lot various phones, which belong to the average price category. Such models are usually characterized by average price and quality indicators.

    And today we will talk about such a strong middling product from the South Korean company Samsung. It's about samsung phone galaxy j1. But first you need to say a few words about the manufacturing company.

    The South Korean company Samsung, which represents a whole group of companies, was founded back in 1938. On the global market today, the company positions itself as a manufacturer of high-tech components, as well as a creator household appliances, equipment for the telecommunications sector, video and audio devices. The main office of the company is located in the capital South Korea, Seoul.

    The word "Samsung" means three stars in Korean. There is a version that the founder of the company, Lee Byung-chul, thus wanted to emphasize the presence of three sons. By the way, it was Lee Kun-hee's youngest son who headed the company in 1987, in violation of the Eastern tradition, when it is the eldest son who should inherit his father's business.

    Unfortunately, in the late 2000s, a serious crisis emerged in the company due to several consecutive corruption scandals that shook the company's management. During that period, Samsung significantly lost ground in the race of mobile phone manufacturers. By the way, this year the company was also rocked by a corruption scandal.

    Things went well for the company When did the development of phones begin? Galaxy series. Particularly important in this was Samsung Galaxy S2, which literally pulled the company out of second-rate positions and returned it to the club of the largest mobile equipment manufacturers.

    Today the company's turnover is about 300 billion dollars, and net profit is about 40 billion dollars a year. The company managed to become one of the largest manufacturers of electronic devices in the world.

    Appearance


    Externally, this phone is a typical classic device from Samsung. It's well made and has a border around the screen that makes it look much more presentable. It supplies the market in three colors:

    • blue;
    • black;
    • white with a pearlescent tint.

    The body is made of plastic. But the plastic used is really high quality, which sets it apart from its competitors. On the left side there is a paired volume control button, and on the right side there is a power on/off key for the device. There is a MicroUSB connector at the bottom end, and a 3.5 mm audio jack at the top.

    If you open back cover, then there will be a removable battery with a capacity of 1850 mAh, as well as two connectors for micro (in models with one card, there is no second slot, instead there is a plug), as well as a connector for microSD.

    Using the phone is very simple and convenient, as it fits well in the hand and weighs only 122 grams. And it’s very easy to hide it in a clothing pocket given its dimensions - 129x68.2x8.9 mm. Under the screen there is a mechanical key, as well as two touch ones. From the point of view appearance There are no complaints. The assembly can also be described as high quality - there is no play or creaking anywhere.

    About the display


    Let's start with the display characteristics. It has a diagonal of 4.3 inches with a resolution of 480 by 800 pixels. The pixel density here is 217 ppi, which is budget model very, very good. The display belongs to the capacitive category. A TFT matrix is ​​installed here, which is more than normal for a budget model. It can be described as bright and clearly visible in conditions of both insufficient and excessive lighting, including on the street.

    The 2016 model has a 4.5-inch Amoled display with a resolution of 800 by 480. The dots per inch is 207 ppi.

    Specifications


    If we talk about the technical characteristics of this Galaxy model, then the heart of this smartphone, depending on the version, may be: a 2-core processor of the SpreadtrumSC8830 model with a core frequency of up to 1.2 GHz; This version of the phone shows about 12,000 points in Aututu. 4-core processor model Marvell PXA1908 with core frequency up to 1.2 GHz. Both versions have a Vivante GC7000UL GPU.

    By the way, there is also a 2016 version, where the heart of the smartphone is the Samsung Exynos 3475 chip. It belongs to the 4-core category and has a frequency of 1.3 GHz. In this modification it is installed graphics chip Mali-T720, which operates at 533 MHz. This model also has 1 gigabyte installed RAM, and the built-in storage received 8 gigabytes. This version of the smartphone scores 21000 points in Antutu.

    If we talk about RAM, then 512 megabytes are installed here. And in the second version it is set to 768. Speaking of physical storage, it should be noted that the built-in memory is 4 gigabytes, of which only two are available to the user. It should be noted here important point— one of the versions has support for memory cards MicroSD format up to 128 gigabytes, but not in the mini model. This is very important to know when purchasing in order to purchase exactly what the user needs.

    If we talk about the model with a 2-core processor, then the interface here is extremely slow, jerky and generally not pleasant to the eye. But the second model is much more interesting. This Galaxy collects almost 22 thousand parrots in Antutu, which is pretty good, and there are certainly no problems with the interface, which is really nice. It works quickly and efficiently, and is really comfortable to use.

    If we talk about software characteristics, it works in the operating room Android system Models 4.4.4 Kitkat. Naturally, no update to version 5 is expected, since even the chipset itself simply does not support this system. Although we can only hope for the best. Everything is standard here: notes, voice recorder, calculator, and so on. The only thing I would like to draw attention to is the presence of an FM radio that works with the headset.

    Also, if desired, you can record directly from the broadcast. The 2016 model runs on 5.1 Lollipop. There are no plans to update to version 6.0 Marshmallow.

    About the camera


    Front camera this model has a two-megapixel module, and its quality is quite excellent, for a budget employee. The main camera has a 5-megapixel module. It has automatic focus and can also record HD video at 30 frames per second. The camera shoots somewhat slowly, but the pictures look normal, considering the fact that the Samsung galaxy j1 mini is a budget device.

    There are also a couple of rather interesting possibilities here, namely, the device can recognize a raised hand and take a selfie (the so-called selfie mode). Or it can take a photo while pressing the screen. In the interface you can find various applications, which will allow you to apply various types of filters. There are even settings that allow you to adjust the values ​​of parameters such as ISO, exposure and white balance.

    In general, the quality of the images can be called quite acceptable. During the day, the photos turn out to be quite high quality. White balance is automatically selected correctly in normal lighting. Color rendition is also normal, the indicators of which are quite close to natural. If the user needs, then making some kind of photo note, photographing text, scanning will not be a problem with such a camera. But at night or in low light conditions, pronounced noise appears and detail is lost, but overall this cannot be called surprising.

    And if we talk about the 2016 model, the main camera has a 5-megapixel module. The lens aperture in this case will be f/2.2. It also has auto focus and LED flash. Also, it has a 2 megapixel front camera. In addition, this model can make HD video files at a resolution of 1280 by 720 at 30 frames per second.

    About wireless interfaces


    If we go to the description wireless interfaces, then there are slots for two Micro-Sim cards. Also, the device we are interested in works both in 2G networks and can work in 3G networks. An 802.11 Wi-Fi module with support for b/g/n protocols is also installed here. Also, there is a Bluetooth module version 4.0. It is logical that there is no NFC module. But there is support for GPS and GLONASS modules. Note that the speed of searching for satellites is quite low. But here, most likely, the issue is not in the antenna itself, but in the “slowness” of the phone itself.

    By the way, the F version of the phone has, How NFC support, and support for 4G-LTE networks. In addition, using USB cable 2.0 and the Kies service can connect the phone to a personal computer.

    The new 2016 model has support for two SIM cards. The phone can operate on both 2G and 3G networks. GPS\GLONASS navigation is supported here, and is also present. Single-band Wi-Fi is installed here.


    If we talk about the battery, then a removable one is installed here lithium ion battery capacity 1850 mAh. The manufacturer claims that thanks to it, the smartphone can work up to 9 hours on the Internet, both on 3G and Wi-Fi. Also, the device can talk for up to 10 hours and play music for 40 hours. In real conditions, this phone works for a day under very heavy loads, but users can count on two days of work under normal loads. This is a pretty good result, which became possible thanks to the use of a non-top processor, as well as a display.

    In addition, SamsungGalaxyJ1 has energy saving mode, in which everything except the basic functions is simply disabled. Naturally, the operating time in this mode increases. True, if we take into account that this screen has a TFT matrix, then there is not an extremely large increase here when compared with other devices from the company.

    The battery can be fully charged in 1 hour and 45 minutes. Naturally, no modes fast charging or something similar is not here and cannot be in general.

    And the 2016 model has a removable 2050 mAh battery. In general, it has the same autonomy indicators as the models under consideration, but still, if it has an Amoled display, such a solution will be more profitable and interesting than the model we are considering.

    As a result

    Generally speaking, we can say that the phone provides high-quality communication. The vibration alert can be called average, but a regular call is clearly distinguishable. It will be heard even in a noisy place.

    Unfortunately, Samsung versions There are quite a lot of Galaxy J1s, which makes it extremely easy to get confused among them. If the cheapest models, frankly speaking, cause nothing but regret, then the model with support for LTE and NFC does not seem so hopeless. True, based on the price you can quickly guess which model is in front of you.

    If we talk about the advantages of the model, we should highlight:

    • availability of several versions;
    • high-quality battery optimization;
    • good display colors, good angles review;
    • high quality plastic case.

    If we talk about the shortcomings of the model, we should highlight:

    • the presence of a small amount of RAM;
    • Some models support only 1 SIM card;
    • small physical storage volume;
    • Some models do not support 4G-LTE;
    • lack of NFC support in some models;
    • display made using TFT technology;
    • rather mediocre performance of both the main and front cameras;
    • low display resolution.

    In general, as you can see, we have before us a family of typical budget phones. Only latest model seriously stands out among the devices in this series. Such a phone will be of interest primarily to those users who are looking for a phone with a minimum of functions and technical characteristics, but want it to have affordable price. And that’s exactly what the SamsungGalaxyJ1 is – simple and reliable. That is why it makes sense to buy it against the background of competitors who cannot offer as many reliable solutions in this price segment. But if the user is looking for something more powerful, then such a solution is unlikely to satisfy him.
