Quite often, users wonder how on a smartphone Xiaomi Redmi Note 4X set up camera? This is due to the fact that, at times, the quality of the shooting does not correspond to the desired level. For example, obvious noise is noticeable when shooting indoors with low lighting or when night shooting. Fortunately, the manufacturer left the opportunity for users to try to set up the camera on Xiaomi Redmi Note 4X on their own.
How to set up the camera on Xiaomi Redmi Note 4X - highlights
Before delving into the settings, you need to install maximum quality Images. It is possible that the image quality has been reduced. To do this, go to the camera settings menu and select the item - "Photo quality" and set the maximum resolution. This action allows you to reduce the level of image compression, which causes noise. The lower the compression, the more detail and quality.
You should also visit the "Frame Format" section. There are two options to choose from - standard and widescreen. It should be noted that in the standard mode (4:3) the entire area of the sensitive matrix of the camera is used during shooting. And when using the widescreen mode, the upper and lower parts of the matrix are cut off. Consequently, the photo no longer contains 16 MP, but a little less.
How to set up the camera on Xiaomi Redmi Note 4X - determining the device version
It should be noted that the quality of shooting may largely depend on the quality of the camera installed on the smartphone. It's no secret that manufacturers in the same smartphone model can use parts from different companies. So, in the Xiaomi Redmi Note 4x model, the camera can be one of the following manufacturers:
- imx258 - Sony;
- s5k5e8 - Samsung;
- qtech_ov13855 - OmniVision;

From advanced settings you need to pay attention to sharpness, saturation, contrast and exposure mode. These parameters are configured at your discretion, so that you get best picture. A little more settings is revealed in manual mode shooting. For example, you can set the exposure time, adjust the white balance, and so on. However, keep in mind that in this case, the time spent on shooting increases. Naturally, in this case it is better to use a tripod so that blur from hand trembling is not added to the noise.

Xiaomi smartphones are the bestsellers because they are among the best among budget phones. In their characteristics, there are many more pluses than minuses, and analogues from other manufacturers are much more expensive. But there are surprises too! Here is one of these - these are different screens for the same phones of the Redmi 4 line.
And here we look at the differences between two identical smartphones. Xiaomi Redmi 4 Pro Grey.
Bought them on AliExpress from different sellers. And at first glance, they are exactly the same. There and there the firmware is stable global 8.1.2.0. But upon closer examination, they turned out to be different!
On the display below, one of the navigation buttons turned out to be gray and the other mirrored. You can see it in the photo.
As it turned out, different matrices are now installed on Xiaomi Redmi 4 smartphones, from different manufacturers are Tianma and EBBG.
How to determine Tianma or EBBG is on the phone?
To do this, go to settings and select "about phone"
In the menu that appears, press the bottom button " DEVICE VIEW» .
The screen manufacturer and version are now listed at the top.
Now it turns out that in the photo on the left is Tianma, and on the right is EBBG.
In this video, you can see in full how to determine the manufacturer of the EBBG or Tianma matrix on Xiaomi Redmi 4 Pro:
Upon further testing, I found that EBBG does not respond in the "Bright" or "Brilliant" mode.
This is inherent in all screens of this manufacturer and is not considered a technical defect.
Which screen is better EBBG or Tianma? There is no definite answer to this question. Technically they are the same. It's more a matter of taste.
Here are the survey statistics from the 4pda website:
We think that many have had such cases when, after some time, after buying, some “gadget” (smartphone, tablet, laptop, etc.), certain problems were revealed in its work. Perhaps you did not use some functions in the first couple of days after purchase, and when you decided to try them in action, they turned out to be not working (this may be a Wi-fi module, 3G (4G), Bluetooth, a 3.5 mm jack for connecting headphones, etc.). If a new device was bought, then in a couple of days, something could hardly have happened to it (unless, of course, it was drowned, dropped, etc. during this period), from here we can conclude that this is a factory defect. In this article, we will tell you how to test the device for defects using the Engineering menu before buying.
ENGINEERING MENU is a built-in utility that allows you to view data about installed components in a smartphone (tablet), as well as check their performance. This utility initially installed on all smartphones (no need to install third-party software), which makes it possible to quickly check compliance with the declared technical specifications, as well as test all components of the device.
Example:
It's no secret that in the same model of Xiaomi smartphones, different display matrices can be installed. Engineering menu(hereinafter referred to as “IM”) allows, before buying, with the type of matrix that, in your opinion (or according to experts), is considered the best, and immediately check it “for broken pixels”. You can also see which camera modules are installed in this device.
The "IM" presents a large number of tests that can easily detect a malfunction of any smartphone module. Also, there is the ability to configure some components, for example, the calibration of sensors. Next, we will describe in more detail all the possible functions of "IM".
HOW TO ENTER "IM"?
There are several ways to enter:
1. In standard application "Phone" (in third-party "dialers" - does not work), dial: *#*#6484#*#*
This combination is the most common, but if it doesn't work for you, then try the following options: *#*#3646633#*#* or *#*#4636#*#*
2. Go to "Settings" - "About phone" - click 5 times in a row on the item "Kernel version"
until "IM" appears
Now consider all the points of "IM" in more detail:
1.Software version
This is the first and only item that displays information about installed components, their manufacturers, IDs, and versions, all subsequent items are tests. When you exit this item, "IM" will offer to pass a full test.
If you click “OK” now, the entire test cycle will start, if you select “Cancel”, you will return to home page"THEM".
So, let's move on to the tests and their description.
2.SIM test
At this point, the installed in the smartphone are tested SIM cards, an example of passing the test is as follows:
Press "OK" to move to the next test. When you click "Error", you return to the main page "IM" (this will be the case in all tests, we will not focus on this further).
3.color
This test is for identifying dead pixels on a smartphone screen. If you have the opportunity to conduct this test before buying a smartphone (you buy in a store, and do not order via the Internet), make sure you do it(of course, this is only relevant for displays with IPS matrix, Amoled displays do not have this drawback, due to design feature). If you find the presence of a broken pixel (or several) after the purchase, no seller (whether it is a regular store in your city or an online store) will replace it with another one with a normal screen. the presence of a broken pixel (even a few) is not a warranty case, their presence is allowed, and in such an amount that you can never dispute that your phone really has a “factory defect”. There were cases when a smartphone ordered through an online store (Aliexpress) had a dead pixel (it glowed white on a black background, right in the center of the screen, it looked very “disgusting”, especially when watching a video). I had to “communicate” with the seller for a very long time about this (because a dispute was opened), who did not want to compensate for part of the acquisition costs this smartphone, arguing this just by the fact that this is not considered a marriage. As a result, we managed to agree on the amount of compensation of $ 10 (when opening a dispute, more was claimed). What is most interesting, this pixel was cured using the program "Pixel Fixer", and to this day the smartphone has no problems displaying information on the display (more than 1.5 years).
On the desktop, everyday use, a dead pixel may not show up. It can glow in any color on a black background, or vice versa, on a white one. There are options for the glow and other colors. That is why this test presents the primary colors, on which it is quite easy to identify a dead pixel, if any. When conducting this test, it is better to turn on the maximum brightness of the screen.
4. Touchpanel self test
The screen test passes without user intervention, after which it moves on to the next test.

- What
- How does it work
It is important to say that not always certain settings will provide best result. Conditions will always change, including lighting. Change settings for higher quality.
One practical example is the use of flash. In the daytime, it is useless, and sometimes even spoils the whole frame. If you are working in dark conditions, highlighting objects can guarantee the best result.
How to improve video quality?
Setting the video quality toXiaomi nothing more complicated than the steps needed to get amazing shots. Open the camera and do the following:
Step 1.
Select the "Modes" section, and then "Open Settings".
Step 2

Step 3
Very important focus mode. It depends on how high quality the video material will be. By choosing continuous focus mode(CAF), you do not have to monitor the clarity of the image, your phone will take care of it.
But there are always special cases. If you need a stable change of focus on a particular subject, use the manual mode.
If you are aiming for the perfect video, some video shooting tips will be very helpful. Try to use manual focus if you are targeting a specific object.
Also, use a flash in low light. good video will be when you take care of image stabilization. Even if you hold the device with two hands, the shaking will be greatly reduced.
In order for you to experience the convenience of viewing everything that you have filmed, it is better to create horizontal videos. A computer, laptop or TV is more adapted to this format, so you will enjoy your video to the maximum.
Do not make sudden movements with the camera. Sometimes the power is simply not enough and the output is only a blurry picture. Make any video smooth, it will add to its attractiveness.
Mobile phones from the company xiaomi gained immense popularity all over the world. Today, we can safely say that these gadgets are among the most popular on the market. The manufacturer did a great job not only on the quality of its products, but also on its characteristic appearance. Brand recognition xiaomi grows every day.
Another advantage of the company is an extensive range of mobile devices. On the other hand, this is also a disadvantage, since it is often difficult for the buyer not to get confused in the variety and make right choice. Many smartphone users do not even know which model Xiaomi phone they have. This information is very important, because knowledge of a specific model mobile device will help in installing updates for the gadget and downloading different applications for him.
That is why for many users the question is relevant: how to check which phone model xiaomi did they purchase? Of course, it is quite possible to determine the exact name of the gadget even after you bought it and immediately threw away all the documents supplied in the kit, and even the box itself. In today's article, we will tell you how to do it.
visual signs
Although inside model range and individual Xiaomi lines and there are no significant differences in design, it is still possible to determine the model of the device by evaluating its visual features.
First of all, look at whether the case of your device is made of metal, ceramic or plastic. If you see a plastic case, then with a very high degree of probability in front of you is a representative of the Xiaomi Redmi budget line. Of course, it will also be necessary to define specific model gadget.
This will help analyze the location of functional elements. On some models (mostly older ones) there is no fingerprint scanner. On more modern gadgets of both the budget and the flagship line, the scanner is mandatory. However, its location is changing. For example, in the third generation of Redmi, the scanner hit the back, and in the flagship Mi5 we see it on the front panel just below the screen.
The differences relate to the location of the front camera, proximity sensor, headphone jack and other details. And such a comparison of gadgets gives a fairly accurate idea of which phone you own. However, you will have to thoroughly immerse yourself in the study of the features of each smartphone released by the company. xiaomi. This, of course, will require a remarkable investment of time and effort from you.
One thing is good in this situation - there is a much simpler answer to the question of how to recognize the Xiaomi model.
Give gifts
Look in the settings
If you have not yet studied the smartphone settings in sufficient detail or just recently purchased it, then you are unlikely to know that the manufacturer indicates the gadget model in the settings. This information is most conveniently viewed in the section "About phone". By the way, here is some other useful information. For example, about the version installed firmware and the amount of RAM and internal memory. This data will help you get a comprehensive picture of what kind of phone you have in your hands.
Well, in order not to doubt that in the settings item "About phone" true information is indicated, we recommend buying gadgets only in those companies that can be considered trusted. They must have enough positive feedback and be on the market for a long time. Of course, it is ideal if one of your friends or acquaintances has already made a purchase in the company and then recommended it to you, but, as practice shows, it is quite possible to rely even on the reviews of strangers.
Also, be sure to check if the IMEI code is indicated on the delivery box. Its absence should a priori alert, because this combination of numbers is unique for each mobile device and must be present in any case. If it is, then you should enter this code on the official website of the manufacturer to make sure that you did not purchase a fake.
