Samsung S7 How to Enable IR Port

In its previous flagship, Galaxy S6, Samsung introduced several bold solutions that were not warmly received by users. Fortunately, the manufacturer heard criticism and took into account the main complaint of customers, returning the memory card slot to the Galaxy S7. In addition, the gadget received a traditional increase in productivity, a larger amount of RAM and a new camera, which although it has a lower resolution, but it shoots much better in the dark. This is only a small part of the “chips” of the novelty, if you want to get to know everyone. welcome to cat.

Packaging and equipment

The Samsung Galaxy S7 comes with a power supply, a micro-USB cable, earplugs and a set of documentation. In addition, the company’s flagships are now equipped with USB OTG adapters for connecting external drives and peripheral devices to devices. a useful trifle.

Samsung S7 How to Enable IR Port


Apparently, Samsung considered the design of its previous flagship to be successful, and therefore it almost without changes migrated to the new model. As before, the front and back panels of the smartphone are made of glass, and a metal frame protects the case around the perimeter. The most noticeable innovation in the case is the beveled edges of the rear panel, which makes the device a little more comfortable in the hand.

The lens of the main camera sticks out noticeably less, and to the right of it there are still an LED flash and pulse sensors and SpO2 (a sensor of blood oxygen saturation).

On the front panel above the display are the earpiece, front camera and proximity and light sensors, and below the display are the touch buttons “Back” and “Application Manager”, as well as a mechanical key “Home”, combined with a fingerprint scanner.

Separate volume buttons are placed on the left side of the device, and the power button is on the right side.

The top end of the device is occupied by a microphone and a slot for a nano-SIM SIM card and microSD memory card. At the bottom there is a micro-USB port, a 3.5 mm audio jack, a main speaker and another microphone.

Both panels of the smartphone are protected by the latest generation Corning glass. Gorilla Glass 4. But if the front panel is coated with a high-quality oleophobic coating, due to which there are practically no prints left on it, there is no such coating on the rear panel. As a result, you need to monitor the appearance of the gadget, because in real life it quickly gets dirty.


Nowadays, a device with a display diagonal of 5.1 inches does not turn out to be called a big language. We have long been accustomed to such devices and can easily use them with one hand. In addition, the streamlined Galaxy S7 body really fits comfortably in your hand and does not crash into your palm when you try to reach your upper left corner with your thumb. But, if your smartphone’s display still seems large, you can turn on one of two control modes with one hand. The first shifts the keyboard and button interface of a number of standard programs, for example, a dialer and a calculator, to one of the lower corners. The second mode shifts the entire interface to the corner of the screen and can be switched on by triple pressing the “Home” button.


Galaxy S7 is equipped with a Super AMOLED display with a huge resolution of 2560 × 1440 pixels (QHD), which gives a pixel density of about 577 ppi. Without a microscope, it is simply impossible to discern irregularities in the display of even small elements on such a screen. the picture looks completely realistic. The transmission quality, contrast and maximum brightness also deserve all praise.

But even the best AMOLED displays still suffer from color distortion when tilting the device. the gamma shifts a little to the colder spectrum. This does not interfere with the everyday use of the smartphone and does not spoil the impression of the gadget, but this feature should be borne in mind.

As in other Samsung devices with AMOLED screens, the Galaxy S7 can adjust the color saturation by standard means. The maximum saturation shows everything that such matrices are capable of, and the minimum can be useful to those who are used to IPS displays.

Adaptive brightness control in the screens of Samsung smartphones has worked fine before, but now it will focus not only on the readings of the ambient light sensor, but also on your preferences. When adjusting the brightness manually from the notification panel, the smartphone will remember your choice and, in the future, under the same conditions of external illumination, will offer you the same option.


Samsung Galaxy S7 is running Android version 6.0 Marshmallow, on top of which, as always, the manufacturer’s proprietary shell is installed. TouchWiz. The launcher design in the latest version came even closer to Material Design, it became really nice to use it. The most important change in the shell that all users of Samsung smartphones have been waiting for so long is the disappearance of “eared” avatars in the contact lists, now the first letter of the name is simply displayed instead.

This is partly a joke, but it is precisely such trifles that create the overall impression of a smartphone. Such changes affected not only the contacts, but also the notification panel, which changed the gamut. now the switches in it have become blue icons on a white background, and the “Quick Connection” item, which interferes with many, can be removed in the settings. Despite the absence of fundamental changes, TouchWiz has become cleaner and more modern. now even AOSP adherents will like the shell.

The word “cleaner” means not only the appearance of the launcher, but also pre-installed programs. Of course, there are still a lot of them, but there is no longer the dominance of the motley applications of third-party developers that was before. In addition to the Samsung and Google programs, the smartphone comes pre-installed with an office suite from Microsoft, which offers as a gift 100 GB in the cloud of OneDrive, Facebook, WhatsApp, Instagram, Ubank and Yandex. If you do not need these programs, then applications from Microsoft can be disabled by removing them from the list of programs, and all the rest can simply be deleted.

In addition, when buying a smartphone, Samsung gives the owner a number of paid programs and subscriptions. These include six free maps from Navitel, 25 books from LitRes, and a three-month subscription to

Despite the external simplicity, TouchWiz retained a lot of different functions, which has always been its main feature. Since the main “features” of the shell like eye tracking or gesture control were in TouchWiz before, the review will discuss new features of the shell. One of them appeared not so long ago with the next OTA update. scaling. The scaling work, in fact, is similar to the programmatic change of dpi, which is possible by third-party methods only with superuser rights. When you turn on the compressed scale and reboot the device, all the elements on the screen will be reduced and more information will be displayed: you can see an example in the screenshots below. Nevertheless, even with a compressed scale, some elements still look too large. let’s hope that in the future Samsung will add more options for changing dpi.

The Galaxy Labs section also appeared in the settings of the new TouchWiz, in which Samsung plans to add test functions before deciding on their final implementation in the firmware. Now there are two such functions. transferring the shortcuts of all applications from a separate panel to the desktops and quickly calling up contacts by pronouncing their names when the Home button is pressed.

Another new feature is the always-on display. Even when the smartphone is locked, various information, such as a clock or calendar, can be displayed on the screen. Thanks to AMOLED technology, this function has almost no effect on the battery life of the device.

One cannot but mention the multi-window mode, which first appeared on smartphones in Samsung gadgets. You can work in this mode in two ways at once: by dividing the screen into two parts, or by opening several floating windows that can overlap each other. In both modes, you can resize windows and drag information between them (if the applications themselves support this).

The device is in operation

Samsung has released several versions of the smartphone, including with a Qualcomm processor, but the test was based on the Samsung G930F, which is intended for sale in Europe, including. This version is equipped with a 64-bit Samsung Exynos 8890 Octa chipset based on ARM big.LITTLE architecture. The chipset includes four 2.4 GHz Samsung Mongoose cores, four 1.3 GHz ARM Cortex-A53 cores and an ARM Mali-T880 MP12 graphics accelerator. The kernels of Mongoose were the first in-house development of a South Korean company and are improved ARM Cortex kernels. It will not be superfluous to note that the Exynos 8890 is one of two mobile chipsets in the world based on the 14-nm process technology. In addition, the device received 4 GB of RAM standard LPDDR4, as well as 32 or 64 GB of internal memory standard UHS 2.0. this is the fastest memory in mobile devices to date. A model with 32 GB of memory arrived for testing, only about 20 GB is available to the user from it, but this will not become an obstacle: the microSD slot was returned to Samsung‘s flagships, supporting cards up to 200 GB in size. Also, if necessary, you can use the bundled USB OTG adapter and connect an external drive to your smartphone.

There is no need for extra words about S7 performance. it is one of the fastest and most powerful smartphones in the world today, it copes with all games and other tasks without problems.

Speaking of games: in the Galaxy S7, the manufacturer decided to focus on them by adding the Game Launcher application to the firmware. This is a catalog of games installed on the smartphone with a number of special functions. These include turning off notifications, reducing power consumption in games, which is achieved by lowering the resolution and the number of fps, as well as Game Tools. a floating icon, by clicking on which the context menu opens. Its most useful features are disabling the touch navigation buttons and recording from the screen.

AnTuTu and 3DMark test results can be seen in the screenshots.

One of Samsung‘s flagship flagship chips is a fingerprint scanner built into the Home button. The scanner works flawlessly: to turn on the screen and unlock the device, just hold the button for no more than a second. Whoever says anything, but the location of the scanner on the front panel is the best of all possible: before unlocking, you do not need to press the power button and there is no difficulty when turning on the gadget when it is on the table. In addition to unlocking the smartphone, the Galaxy S7 scanner can be used to log into your Samsung account and to log in to sites in a standard browser.

Two more sensors that have become the hallmark of Samsung‘s flagships are a heart rate monitor and a blood oxygen sensor. Pulse, SpO2, and stress levels are measured through the S Health app, where you can also keep a diary of weight, exercise, and other health-related events. A number of measurements can be automated. S Health supports the connection of third-party accessories, including the ANT technology.

Perhaps the only real oddity of this smartphone is the use of a micro-USB port instead of USB Type C. This is not a very clear solution for the flagship in the era of mass transition to a more convenient standard, and, moreover, USB Type C is easier to make using the USB 3.0 standard The micro-USB 3.0 port is large in size and has not taken root in smartphones, so Galaxy S7 owners will have to be content with USB 2.0 speed.


The Galaxy S7 uses a 12-megapixel Sony IMX260 module as the main camera. this sensor was created specifically for Samsung and is not sold to other manufacturers. Compared with the previous version of the flagship, the camera resolution in the Galaxy S7 fell, but this happened due to the increase in the physical size of each pixel, so the smartphone began to shoot fine in the dark. Another advantage of the new sensor is an improved phase autofocus, in which all the pixels of the matrix are involved, against about 5% in previous models. The result is instant focus, even in difficult conditions, and given the overall speed of the smartphone, the gadget is ready to shoot in less than a second when you open the camera.

All this has led to the fact that the Galaxy S7 is now one of the best cameras among mobile devices, which copes with almost all scenes, including shooting in low light. Small artifacts may appear only in night photos. You can evaluate the quality of images using the examples below.

Close-ups with flash. And so without a flash.

HDR photo HDR off

We’ll separately say about the Panorama mode, in which full-size photographs are glued together, and the final resolution of such images is 38 megapixels.

recording on the main camera is possible in resolutions up to Ultra HD, and the maximum frame rate for the standard shooting mode. 60 fps. is achieved in Full HD resolution. In slow motion mode, the speed increases to 240 fps, but the resolution drops to HD. Thanks to optical stabilization, thes come out clear and smooth, and if you turn on the HDR, then even the bright sun will not interfere with the creation of the.

Slow Motion Example

The front camera did not disappoint either: at a resolution of 5 megapixels, it allows you to take excellent selfies. Of course, there are various “face improvers” that correct the color and texture of the skin.

Wireless interfaces

As befits a top-end smartphone, the Samsung Galaxy S7 has a complete set of all wireless interfaces: Wi-Fi 802.11a / b / g / n / ac with support for the 2.4 and 5 GHz frequency bands, Bluetooth 4.2 with low power consumption, NFC and ANT. It is worth mentioning the new modem mode in the smartphone: now, when a Wi-Fi access point is activated on the gadget, the smartphone will share the Internet connection not only through cellular networks, but also through other access points. In fact, this means working in repeater mode, which is useful when traveling, to quickly connect all your devices to Wi-Fi, as well as at home if your router doesn’t “finish off” to the far room.

There are no problems with cellular communication either, the speed of data transmission via LTE is limited only by the capabilities of operators, and the huge number of supported channels will allow using high-speed Internet connection in almost all countries.

Offline work

The gadget is equipped with a non-removable 3000 mAh battery, and even in this section you can not immediately say about a number of “chips”. Firstly, it is Quick Charge 2.0, which allows you to charge the battery by 60% in 30 minutes. Secondly, the smartphone supports wireless charging immediately according to two standards, Qi and PMA. over, wireless charging can also be quick (full battery charge in 90 minutes), if the stand supports the corresponding function. Finally, the extreme energy saving mode has not gone away, in which a smartphone with a couple of remaining percentages can stretch for several more hours.

In addition, the manufacturer carried out other work to optimize the energy consumption of the smartphone, which resulted in a full day of battery life with a screen runtime of more than four hours. If you are not using gadgets so actively, then your Galaxy S7 can work both a half and two days. in standby mode, the device consumes very little energy.

The results of testing the gadget’s autonomy in continuous loads are also impressive: in games at medium brightness the S7 lasted exactly 10 hours, and when playing Full HD in flight mode at full brightness. more than 14 hours.


Samsung continues to hold a leading position among manufacturers of Android smartphones. Galaxy S7, like other flagships of the company, uses the latest technology, has a huge margin of performance, and it may take more than one day to study all its functions and customization capabilities. Special attention should be paid to the camera, which produces perfect pictures during the day and just good photos at night. not many other mobile gadgets can come close to it in quality. Well, the noticeably increased autonomy of the device and the ability to quickly charge make the situation when the smartphone turns off by the end of the day is almost impossible. Samsung Galaxy S7 has become a smartphone for those who want to get the maximum and are not ready to make any compromises, including the price of the device. Recommended price. 49,990 rubles.
