Gorgeous screen
Now you have even more space for both work and entertainment: a luxurious 5.25-inch screen is ideal for any task - movies, PC games, Internet, work. You no longer have to constantly scroll left and right on web pages or peer at tiny letters - on the large screen of the GALAXY Grand 2, you can use the Internet in almost the same way as on your usual laptop.
Multi-window support
But the big screen in Samsung smartphones is not just a big screen, but also a unique multitasking mode in which you can open two applications at once and even drag and drop various objects between them, for example, a photo from the gallery to an email. Pull the icon located in the middle of the left edge of the screen and select first one and then the second program. A map and a letter with an address? SMS-correspondence and the schedule of cinema sessions? Facebook and browser? On the same screen, at the same time? With GALAXY Grand 2 it's easy!
A wealth of possibilities
Speed and functionality
GALAXY Grand 2 not only features an excellent screen, but also a powerful 4-core processor, a large amount of memory (note: using microSD cards, you can easily add up to 64 GB of permanent memory at any time!) And support for modern wireless interfaces, including Wi-Fi in both bands (2.4 and 5 GHz) and Bluetooth 4.0. All this means that the smartphone will easily cope with almost any task, and Internet access, downloading music, movies and new applications will be smooth and fast.
Support for 2 SIM cards
The smartphone has support for two SIM-cards - which means you can combine work and personal phone numbers at home or home and local when traveling abroad. At the same time, Dual Standby technology ensures that both SIM cards can work simultaneously, and you will not miss a call, no matter which of the two numbers it comes to.
2, a review of which is presented in this article, debuted on the domestic market quite recently. In general, the novelty has retained a stylish modern design, characteristic of the entire line of the South Korean manufacturing company, and also boasts quite impressive technical characteristics.
general description
The body of the model is made of high quality plastic. Now in Russian stores only devices in white (Samsung Galaxy Grand 2 White) are sold. Black and pink versions of this phone are also expected to be available over time. On the front side, a shiny chrome edging catches the eye. As for the finish of the back panel, it imitates leather texture, making the device pleasant to hold. As in many other Samsung smartphones, the volume and power keys are located on the left and right sides, while the button for direct launch of the main camera is absent at all. At the top, the developers installed a headphone jack, and at the bottom, a MicroUSB port. On the back cover, in addition to the eye of the main camera, you can see a speakerphone and an LED flash. The name of the manufacturer is also applied here using a special paint.
Ergonomics and build quality
The model weighs 163 grams. Its dimensions in length, width and thickness, respectively, are 146x75.3x8.95 millimeters. The handset fits quite comfortably in the hand and does not slip out of it even during a long conversation. On the other hand, it is impossible not to note one inconvenience. The fact is that due to the use of a large display, it is rather problematic to control the device with the fingers of one hand. They are only enough to press the keys responsible for activating the main functions of the novelty.
The build quality of the model is also at a high level. The reviews left by the first buyers of the Samsung Galaxy Grand 2 indicate that squeaks of materials and even a slight backlash are not typical for the phone. Removing and replacing the back panel is fairly easy. It should be noted that in order to install an additional memory card, as well as two SIM cards, it is necessary to remove the battery.
Main technical characteristics
The device is based on the Qualcomm Snapdragon 400 processor with four cores, each of which operates at a frequency of 1.2 GHz. The size of the built-in memory is 8 GB. If such a need arises, it is possible to install an additional card (microSD up to 64 GB is supported). As for RAM, the Samsung Galaxy Grand 2 has 1.5 GB. In general, the performance of the device is at a very high level. The speaker, although loud, is not suitable for playing music. The novelty supports Dual SIM Standby. At the same time, both SIM cards are suitable for GSM and 3G standards. Both of them can be used to make calls or transfer data. Priority options are implemented in the settings. Many users note excellent sound clarity and audibility of the interlocutor even when operating in crowded and noisy places. The only serious complaint about the operation of the device is due to the fact that its body heats up significantly during playback of high-definition videos.
Screen
The Samsung Galaxy Grand 2 smartphone uses a 5.25-inch display with a resolution of 1280x720 pixels. It is based on a TFT matrix. As for the density of the displayed image, the number of dots per inch is 280. The screen has rather large viewing angles. If you use the machine in direct sunlight on the display, color loss may occur in certain areas. However, it cannot be called essential. Moreover, when you turn on the maximum backlight level, this flaw is completely smoothed out. The screen sensor can simultaneously recognize up to five touches. The second generation of glass is used to protect it.
cameras
The main camera of the novelty has a matrix of 8 megapixels. It is equipped with auto focus and flash, which can be used both when taking still pictures and when recording movies. Compared with other products from the manufacturer, the camera interface has undergone some changes. Among other things, she received a number of modes, filters and the ability to voice control. Smartphone Grand 2 is also equipped with an additional working with a resolution of 1.9 megapixels. This indicator is quite enough for video communication and creating so-called "selfies" in good quality.
autonomy
The phone uses a removable type with a capacity of 2600 mAh. If you believe the official information of the manufacturer, then without additional recharging the device can operate for 370 hours in standby mode, or 17 hours of continuous talk. If necessary, the user can activate the power saving mode (this application is standard), in which the main parameters and settings are adjusted automatically by the device.
Main advantages and disadvantages
The main advantages of the novelty, experts include support for working with two SIM cards, excellent performance, a large display, as well as high build quality of the device and the materials used to create it. As for the shortcomings, among them one can name perhaps not very large and also not the highest sound quality.
Conclusion
Summing up, it should be noted that the South Korean company managed to develop a decent mid-range smartphone, which, compared with previous models, has significantly improved technical characteristics and ergonomics. Most users who are used to using higher-end devices may not like the screen resolution very much. On the other hand, there is no need to talk about graininess or blurring of the image. As for the cost of Samsung Galaxy Grand 2, the price of the model in the domestic market is within fifteen thousand rubles.
Galaxy Grand 2 SM-G7102. The novelty can be called long-awaited, as its announcement took place in November last year. The device retains the common features characteristic of the Galaxy line and at the same time, the phone has quite powerful technical characteristics. One of the important advantages of a smartphone is the use of two SIM cards at the same time.
Case Samsung Galaxy Grand 2 classic, it is made in the form of a rectangle with rounded edges. Despite the large dimensions, the phone is quite comfortable in the hand and easy to manage. At the moment, only the white version is on sale, later a black plastic model will go on sale. Along the edges of the smartphone is a rim of a shiny chrome frame. As in most Galaxy models, the power and volume buttons are located on the right and left ends. The headphone jack is on the top of the phone, while the micro-USB port is on the bottom of the phone. On the front side of the phone there are control buttons: two touch and one mechanical.
The back cover, as in the Galaxy Note 3, is framed under the skin, which in general looks quite attractive and has not yet become boring to the user. On the back cover of the phone there is a camera window and a speaker grille.
Galaxy Grand 2 measures 146.9 x 75.3 x 8.9mm and weighs 163g.
Performance and software
Our test smartphone passes well and shows a result above average. The Samsung Galaxy Grand 2 G7102 smartphone is equipped with a Qualcomm MSM8226 Snapdragon 400 quad-core processor, with a frequency of 1.2 GHz per core and an Adreno 305 graphics system. The amount of RAM in the new product is 1.5 GB. The internal memory is 8 GB, and the device also supports the installation of a memory slot up to 64 GB. These parameters are more than enough to use any applications and games.
The new model is controlled by Android 4.3 operating system. Installed proprietary interface from Samsung - TouchWiz.
The user has the ability to create seven desktops and place widgets and application icons on them. And also, for the first time, the possibility of multitasking appeared, now you can open 2 applications at the same time on the screen and, for example, copy photos from the gallery directly to the mail application.
The model is equipped with Wi-Fi, GPS/GLONASS and Bluetooth modules. Wi-Fi keeps the signal well and without interruptions, there are no problems with data transfer. Unfortunately LTE is missing.
The device supports two SIM cards (micro-SIM), you can switch between them from the notification menu. It is possible to set priorities for SIM cards, that is, you can use one for calls and use the other for data transfer.
Screen
Compared to its predecessor, the Grand 2, the display is much better. The screen is a 5.25-inch TFT panel with a resolution of 1280x720. Screen colors are bright and saturated. The image is perfectly visible in the sun, regardless of the viewing angle.
Camera
The phone has two cameras: front and rear. The front camera is absolutely ordinary and has a resolution of 1.9 megapixels. The resolution of the matrix of the main camera is 8 megapixels. The camera is equipped with autofocus and LED flash. The camera takes high-quality photos with a resolution of 3264 × 2448 and records video in Full HD. Like other Galaxy models, the camera has several shooting modes.

Battery
The capacity of the battery installed in the Samsung Galaxy Grand 2 smartphone is 2600 mAh. With active use of the device, playing games, using applications, and performing other operations, a full charge of the battery will last approximately one day. With an average load level, the phone will work for about two days without recharging. It takes about three hours to fully charge the battery.
Compared to the previous version, the smartphone has become better in terms of performance and battery capacity. The design has changed a little for the better - the back cover has become more attractive. With these changes, I am glad that the price of the device differs from the first version by about 80 dollars.
