Appearance of the device and equipment

The box is standard, very small, without unnecessary details, in white color, created just in the size of a smartphone. Roomy and budget, like the smartphone itself, it symbolizes the modesty and economy of the option you have chosen.

In principle, Xiaomi smartphones do not really indulge users with various design options for their gadgets, and the 4 series was no exception. The seasoned style is presented in black (black), white (white) and gold (gold) colors. That makes it possible for everyone to choose the right smartphone.

The build quality of a monolithic (non-collapsible) smartphone, back cover which is made of metal, good. The upper part of the rear panel is plastic, for better signal transmission, it is installed tightly and does not creak. There is also a proprietary Mi brand logo, a fingerprint scanner, a camera and a dual flash.

WITH right side the device has two metal buttons: a power button (unlock) and a volume control. They have a nice look and are very convenient when using this smartphone.

The upper part is represented by several important details at once:

• Infrared port (you can control the TV);
• Headphone jack (standard 3.5).

The left and bottom parts have a connector for Charger, two speakers, one of which only outwardly resembles it, but acts as a microphone, a microphone and a SIM card tray.

The front part is represented by the following elements:

• Three touch-sensitive control buttons - not illuminated, as in all economy versions of the Redmi line;
• Sensors - basic and proximity sensor, which provides blocking during a conversation and prevents unwanted pressing;
• Speaker - located centrally on the top of the smartphone case;
• Front camera - located in the upper right corner, does not interfere and captures the most convenient range;
• The 5-inch screen is a high-quality and highly detailed display.

The fingerprint scanner is no different from earlier models. It is located on the back of the device, it works well and is pretty fast. It is not inferior in its capabilities to more expensive models.

Xiaomi Redmi 4 screen

The first thing that catches your eye is the black frame around the contour of the display itself. The best option there will be a choice of a black device that will hide this nuance, but will be somewhat more expensive than other colors due to its popularity.

Comparatively small 5-inch Full HD IPS screen in Xiaomi Redmi fourth with high pixel density and brightness range. So, the resolution is 1920 * 1080, while the pixel density is 443 ppi. It also has a special coating against unnecessary stains on the screen, including prints and greasy marks.

Xiaomi Redmi 4 performance

One of the main advantages of this model is a good and high-quality Qualcomm Snapdragon 625 processor with 8 cores, created by modern technology with a frequency of 2 gigahertz, providing a high-quality and immediate process when using the device.

As for the video, it uses the Adreno 506 accelerator at a maximum frequency of 650 MHz. Allows you to meet the maximum requirements of most popular smartphone applications. It has RAM and built-in memory in 3Gb and 32Gb, respectively.

Excellent performance can be used both during games and in everyday use. Works without slowdowns on complex toys (for example, World of Tanks), which gives it a reason to be called game device for a relatively low cost.

The smartphone is made according to the technological process of 14 nanometers, which will avoid overheating and economically use the battery capacity.

Xiaomi Redmi 4 Pro bypasses original version in RAM on 3Gb and internal memory on 32Gb. Now you can safely open 6-7 tabs and not think about constantly slowing down your smartphone. Although the Pro version is aimed at game process, but still, given the volume of MIUI firmware, it will be useful to the average user.

Sound parameters of the gadget Xiaomi Redmi 4

One of the key factors of use is that the phone is equipped with one speaker and the second is a "trick". Sound that is not distorted and pleasant to the ears. The alarm clock and the bell itself are audible loudly and clearly.

High-quality sound comes both from the speaker and through the headphones, especially since they can be customized for a specific person and his characteristics. Although it is a little muted and not of the highest quality.

Autonomy 4 series Xiaomi

A 4100 mAh battery will allow you to safely use the gadget for two or more days without recharging. It is also impressive that the first version and the Pro are identical in their autonomy with different performance.

So, it will be possible to watch videos on the Internet at maximum rates for more than 9 hours without a break, and use it for Internet surfing for more than 18 hours, which brings it to the top of solutions to problems with autonomy in smartphones.

Internet connection and communication

Thus, if there is a desire to change your smartphone to a popular, high-quality and reliable gadget, then ideal solution in terms of price and quality, there will be Redmi 4.

The difference in numbers is small, but this only applies to price. Their capabilities are quite different, and $ 28 is worth overpaying to arm yourself modern characteristics and trusted company name Xiaomi.

Thanks to its compact size, Xiaomi Redmi 4 Pro is easy to operate with one hand. Generally appearance device does not match its budget origin. Due to the use of metal, it looks stricter and more solid.

The body dimensions of the Redmi 4 Pro are 141.3 x 69.6 x 8.9 mm, which is comparable to. The smartphone cannot be called thin, but it fits comfortably in the hand. At the same time, we note the large weight of the device - 156 grams. For comparison, metal with a slightly larger screen diagonal weighs even less, only 144 grams.

Compared to its predecessor, the design of the smartphone has become more angular. The front panel is covered with 2.5D glass, curved at the edges. At its top are front-camera and speaker, at the bottom - touch-sensitive navigation buttons. On the right side of the case, there is a tray for SIM-cards, combined with a slot for a memory card.

You can buy Xiaomi Redmi 4 Pro in three colors: gold (Gold), dark gray (Dark Gray) and silver (Silver).

Screen - 4.4

As a rule, the screens of inexpensive devices are rather mediocre. They can rarely please with brightness or color accuracy. However, Xiaomi Redmi 4 Pro is not the case. Its screen is able to significantly raise the bar of quality among budget smartphones.

The Redmi 4 Pro is equipped with a Full HD (1920 × 1080 pixels) IPS display with a density of 441 ppi. Colors on the screen look natural with no noticeable deviations. Our colorimeter also confirmed this, showing 96% coverage of the sRGB color space. The colors remain natural when viewed from an acute angle. The contrast ratio we measured was also high - 1000: 1. Maximum display brightness in automatic mode- about 500 nits, the image fades a little in the sun, but still remains well read. The minimum brightness value of 1 nit allows you to comfortably use the device in the dark. Note that a display similar in characteristics is installed in a more expensive one, while its brightness and contrast are somewhat lower.

Cameras - 3.5

The smartphone is equipped with good cameras at 13 and 5 MP, honestly fulfilling their bread.

The 13 MP main camera has an f / 2.2 aperture, phase detection autofocus and dual diode flash. Autofocus works correctly in most cases, without errors. In daylight, shots are sharp, with natural color reproduction. In HDR mode, the image is slightly blurred around the edges of the frame. Night shooting is already difficult for the camera - photos lose sharpness, although color accuracy is preserved. V manual mode it is possible to fine-tune the shooting parameters.

Video shooting is available in Full HD at 30 frames per second. The ability to shoot in 4K is absent, although the processor formally supports video recording in this resolution. It is a pity, however, the price of Redmi 4 Pro allows you to forgive him for this shortcoming.

The front camera has a resolution of 5 MP and an aperture of f / 2.2. The quality of pictures in daylight is good, quite detailed, but the color rendition may seem dull to some. Full HD resolution is available for video calling.

The smartphone is equipped with 32 GB of memory, with the ability to install microSD memory cards up to 256 GB. Yes, the customer is again forced to choose between two SIM cards and additional memory. But similar solutions are now used everywhere, becoming a kind of tradition.

Peculiarities

The smartphone is running a proprietary operating system MIUI 8.0 based on. The main difference from pure Android lies in the huge possibilities for tweaking and customization, as well as in an alternative app store. The latter can be accessed by registering a Mi-account - this will allow you to install various themes, wallpapers and much more.

Many users complain about the very poor sound quality when shooting video with the Xiaomi Redmi 4A phone. Judging by the questions on the MIUI forum, this problem is also present in other Xiaomi Redmi 4 and 3 series phones.

The thing is that noise cancellation is turned on by default in the sound settings, and at the time of this writing, there is no switch in the MIUI interface to turn it off.

Many owners already smartphone Xiaomi Redmi 4A (and other models) sent complaints to developers about this bug, but in new version MIUI firmware(8.5.1.0 at the time of this writing) the sound quality of the camera has not improved. Therefore, there are two options left: wait and hope that in future versions of the firmware they will fix this defect, or fix the bug yourself.

To turn off noise reduction yourself, you need to edit system files... To access the system files, you must first.

For the convenience of making edits to system files, you can use any file manager, which allows you to view and edit system files, we will use the popular ES Explorer file manager (ES Explorer) with a built-in ES Note Editor (ES Editor).

Disabling noise canceling

First of all, you need to enable the ability to view system files. To do this, in the left-hand menu in ES Explorer, activate the "Root Explorer" option. If the root is correctly installed in the phone, a request for granting rights will appear.

In the same menu, expand the "Local storage" group, select the "Device" item, go to the "/ system / etc" directory on the device and find the "audio_platform_info.xml" file. For the convenience of viewing files, you can switch their display as a list. To do this, click on the vertical ellipsis in the right upper corner and select "View", then "Medium, detailed".

Be sure to copy the "audio_platform_info.xml" file (and other system files that you will change) somewhere (for example, to the "Downloads" folder on the memory card) before editing it, since if something goes wrong, you can always restore it from backup... Open the file using the built-in ES Explorer editor (ES Editor or ES Note Editor) and switch to edit mode by clicking on the "Edit" icon on the top bar. Find the line:

and add the following 2 lines below it:

When typing, it is advisable to disable autocorrect on the keyboard, since additional signs, which will lead to the inoperability of the configuration file and, as a result, the inability to record video on the phone or even breakdown of the operating system. To type text in capital letters, hold the power button for a few seconds capital letters to go back to the set of lowercase letters, briefly press it again.

Save the file and check that the permissions are "rw-r −− r−−". To do this, press and hold the file until a green checkmark appears in front of it and context menu... Then click on the vertical ellipsis (More) in the lower right corner and select "Properties".

If in the line "Resolution" the rights differ from "rw − r −− r−−", click the "Change" button and put a tick in the form of the letter "Г".

Increase video recording volume

After turning off noise canceling, the recording sound becomes too quiet. To increase it, in the same folder "/ system / etc" you need to edit the file "mixer_paths_qrd_sku2.xml", but do not forget to make a backup copy of it before that.

Find a snippet of code:

And add lines to it so that the resulting excerpt is as follows:

Do the same with the excerpt:

The resulting code should be as follows:

Save the file and don't forget to check the permissions for it (see above).

Reboot your phone. Everything, you can check the sound of the camera. By the way, the above actions will also improve the recording quality of the voice recorder by Xiaomi phone Redmi 4A.

In the video below, you can hear the sound quality before and after performing the above steps.
