We check Xiaomi in the engineering menu. Xiaomi engineering menu Xiaomi how to enter the engineering menu

Tips for beginners

In the life of any smartphone, there are times when some kind of malfunction occurs. Sooner or later, most users encounter one or another problem. And devices from Xiaomi are no exception. And then a hidden “weapon” comes to the rescue - the Xiaomi engineering menu, thanks to which you can diagnose the phone’s condition in order to identify the cause of the problem. However, not everyone knows how to open this special menu on their device. Today's information will help inexperienced users get into engineering settings.

These settings are hidden from users' eyes. Many people don’t even realize it’s there until they run into problems. The manufacturer intentionally did not place this item in the general settings so that the owner of the smartphone would not accidentally make changes to the MIUI engineering menu, thereby negatively affecting the operation of the device. For example, it may not play music, stop making calls, there may be other negative aspects, including turning the phone into a “brick”. Then you will have to take it to a service center. Therefore, any manipulations here must be carried out very carefully. For a knowledgeable person, on the contrary, the Xiaomi engineering menu with its capabilities can become an indispensable tool for troubleshooting.

Engineering menu functions

With the help of these settings, manufacturers at the final stage fine-tune new devices so that they reach customers already working perfectly. If you have the skills, this operation can be done by an ordinary person. The Xiaomi service menu allows you to carry out about 25 different tests. All key elements of the smartphone are diagnosed, including sensors. It is available on all devices of the Mi and Redmi series, it is easy to use, and no external hardware assistants are needed. There is no need for a service center; you can do everything yourself. Xiaomi's engineering menu is quite extensive in terms of capabilities.


Let's highlight the most used sections:

  • Adjusting the volume in the main and conversational speakers;
  • IMEI repair;
  • Adjusting camera characteristics;
  • Improving the performance of networks and navigation systems;
  • Microphone adjustment;
  • Reduce battery consumption by optimizing the OS.

On the start screen of the Xiaomi engineering menu there are 4 buttons at the top and one at the bottom. They are all responsible for a specific operation. Let's look at them in more detail:

  • Automatic Test. All components are tested automatically.
  • Single Item Test. Check and configure selected items separately.
  • Test Report. Hardware test and display of information about it in detail. If something is faulty, the designation Fail appears, and when everything is in order, Pass. An incomplete check is listed as NOT FEST.
  • SW and WH Test. Software and hardware version.
  • Device View. Shows information about the display, battery, wireless interfaces, processor and much more. Information is provided about the manufacturer of each component. In this item of the Xiaomi Redmi engineering menu, you can also determine whether the device is fake or original.

Ways to enter the Xiaomi engineering menu

There are two common methods to access service settings. As an example, the Redmi Note Note 4X device will be used, but for Xiaomi Redmi 4 Pro and Xiaomi Redmi 4X the rules are also relevant, as for other models of the manufacturer. There is a third method, however, it involves installing third-party software, so we will not consider it the main one.

Let's start with a path to enter the treasured menu that is suitable for almost all Xiaomi devices. To do this, go to the settings, find the “About phone” item there, then slowly click 3 times on the kernel version. If “Done” pops up, press 2 more times.


For the Redmi series, codes are used that are entered on the telephone keypad. First dial the combination *#*6484#*#*. If you can’t access the Xiaomi engineering menu, you should try other options - *#*#4636#*#* or *#*#3646633#*#*. One of them should work, so give it a try.


Sometimes the above methods do not give results. Then you can use special applications. They can be downloaded directly to your mobile device from Google Play. But there is one nuance that is not suitable for everyone - you will need Root rights. We can recommend two programs called MobileUncle Tools and MTK Engineering. We will consider them.

MobileUncle Tools

The developers have endowed the program with high functionality. Today this is one of the best offers, the purpose of which is to enter the engineering menu. But it is only suitable for smartphones based on MediaTek chips. It will be just right for use in Xiaomi Redmi Note 4 with the MTK Helio X20 chipset on board. You can use the application only after rooting the device, that is, obtaining superuser rights. After you confirm that you have Root rights, the engineering mode will open, where you need to select the MTK engineering menu. The program is easy to find on the Internet, but recently it has been missing from Google Play. The downside is that the interface is only in English and Chinese.

MTK Engineering

This application is in high demand. Users appreciated its convenience and ease of use. After downloading, you need to find the Android Testing item in the list to gain access to important data about your smartphone. And you enter the engineering menu after clicking on Engineer Mode.

Conclusion

Using the service menu may be a solution to the problem. Nevertheless, you should only contact it if you are absolutely sure that your efforts will benefit the phone and not harm it. If in doubt, it is better to contact your nearest service center or someone you know with the necessary skills.

Almost every smartphone experiences some kind of software glitch from time to time, the reason for which lies in the device’s firmware. In order to determine the cause and type of problem, there is a special engineering (service) menu in which you can test any module of your Xiaomi and find out what the essence of the problem is.

From this article you will learn how to enter the Xiaomi engineering menu, what it is, and what its functions are.

So, it is a set of hidden device parameters, the purpose of which is to test and correct various errors in its operation. There are simply no such settings in the standard menu, since a user who does not have sufficient experience, knowledge and skills can change the correct settings, thereby harming the system - often as a result of such an “intrusion” the connection in the smartphone is lost, it cannot make calls, and so on . Therefore, be extremely careful with the service settings of the engineering menu.

The main functions of the engineering menu on Android

  • Service test of GPS operation;
  • Microphone and camera settings;
  • Many settings for sound and volume in the main speaker, as well as in the conversational one;
  • Setting up communication networks;
  • IMEI number recovery;
  • OS optimization to reduce battery consumption.
  • How to enter the engineering menu

Let's look at two main methods that will help us enter the Xiaomi engineering menu.

  1. Through settings. It is worth noting that this method is universal, that is, suitable for any Xiaomi phone. So, go to your phone settings, at the very bottom of the list, click on the item "About the phone". Find the line "Kernel version» and click on it three times. Most likely, at the bottom of the screen you will see the inscription “You just have to press 2 more times”- perform this action. Ready!
  2. Xiaomi codes. Open the phone dialer and enter the special code *#*#6484#*#* . After pressing the call button, you will see on the phone display the necessary list of modules to check. If entering with this code does not help, try several other codes: you need to replace the numbers with 3646633 or 4636.

If the engineering menu does not open

If you were unable to complete the desired action using the first two methods, try using special software. We have two great applications in stock that will solve the issue: Mobile Uncle Tools and MTK Engineering. You can find several more similar applications yourself.

  • Mobile Uncle Tools is the most powerful program out there. It allows you to perform many different operations with the phone system. After logging in, click on the button "Engineering Mode"", and then select "Engineering menu" (MTK). Important! To use this program you will need root rights (how to get them is in a separate article). Since the author of this program is a resident of China, you may encounter either the Chinese or English version of the program;
  • MTK Engineering. Install the application, log in. Click on the item "Android Testing", after which you will see information about the phone, battery, wi-fi and full usage statistics. But in the paragraph called "MTK Engineer Mode" you will come across all service settings. Probably, the engineering menu that appears will differ slightly from the list of modules in the Mobile Uncle Tools program or from the items called up in the first two methods, but its essence does not change - you can also adjust the volume, battery consumption and generally change almost any parameters of your device.


Bottom line

The most important thing we would like to say at the end of the article is that please be very careful when fine-tuning your Xiaomi by calling up the engineering menu. If you suddenly need to check any of the phone modules or fix problems, you don’t need to immediately change the settings in the smartphone’s engineering menu, but rather look for useful information or an article on a specific topic for a specific case on our portal. For your convenience, we have translated the functions of the engineering menu:

  • Key – test of mechanical keys for functionality;
  • Blacklight – screen brightness test;
  • TouchPanel – phone sensor test;
  • Tflash – check the memory card;
  • Bluetooth – search for all devices in the access area;
  • SIM Card – testing SIM cards and checking their availability;
  • Vibration – testing vibration;
  • LCD – display color check;
  • GPS – search for various satellites;
  • Gyro – gyroscope;
  • G-sensor – testing speed sensors;
  • Proximity Sensor – this function is responsible for fading the display during a call;
  • Optical sensor – optical sensor;
  • Magnetic sensor – magnetic sensor;
  • RTC – clock (built-in);
  • Receiver – test of the main speaker;
  • Speaker – speaking speaker test;

  • Camera – test the camera and its flash
  • Battery – battery charging and operation test;
  • Wi-fi – search for access points;
  • Torch – flashlight testing.

Quite often, users encounter such an unpleasant phenomenon as reduced sound on their smartphone. There is interference, it is impossible to understand speech, and the music in the headphones is quiet. In this article we will talk about how to increase the volume on Xiaomi through the engineering menu and by changing system files, adjust the sound in the headphones and check the effectiveness of the earpiece without the help of specialists.

3 reasons why your phone has bad sound

The most common reason is initially lowered factory settings. The smartphone has its own set volume, but its quality is quite poor (or low). But do not forget that the following factors often affect the sound:

  1. Mechanical damage. For example, the phone fell on a hard surface. The screen was not damaged, everything worked, but after a while it became noticeable that the sound began to disappear. Here, unfortunately, a trip to the SC is almost always required. We also recommend reading articles from the repair section.
  2. Incorrect settings. The user can accidentally switch modes: “Quiet”, “Outdoor”, “Airplane”, “Meeting”, etc. Usually everything returns with a couple of clicks.
  3. Problem after update. After the next MIUI update (this often happens on weekly firmware), you can notice a significant decrease in the volume of the speaker, both conversational and main. There can be many reasons, but the main one is a simple bug on the developers’ side. In this case, you need to wait for the fix.

How to change the speaker volume through the engineering menu

UPDATE! Starting with version MIUI 9.2, the engineering menu was replaced with a superficial test of your device, so this item can only be performed on lower versions!

This is the most common way to solve the problem. However, it also requires care, since during the setup process it is very easy to mess up the basic parameters, thereby disrupting the stable operation of the device.

Open “Phone” on the desktop and enter the following number: *#*#3646633#*#* (if the first code didn't work, as in my case: *#*#6484#*#* or *#*#4636#*#* ). Then we find the “Hardware” – “Audio” tab. An extensive list of options opens. We need the first five from above, namely:

  • Connected headset;
  • Standard mode;
  • Speakerphone;
  • Speech;
  • Setting up headphones.

Please pay attention! Each section is configured individually. For example, if you are worried about bad sound only during speakerphone, click directly on “Speakerphone”. Next, open “Headset Mode”. “Type” comes first, let’s start with it. Several words in English are displayed: “ring” – “media” – “sph”, etc. Select the one you need and configure it.

Set the value

Go to the “Level” item. Everything is simple here. You need to select the sound volume in the range from 0 to 255. As we understand, 0 is the minimum volume, that is, its virtual absence; 255 is the maximum the device is capable of. You can choose between them: 50, 100, and so on are allowed. The microphone, multimedia, and speakers are configured in a similar way.

Remember that if you select the maximum level of 225, you risk completely ruining the speaker. It will simply stop working. Why does the factory initially set the minimum power for speaker volume? Because this way the phone will last longer.

Increasing the speaker volume

Proceed with this procedure only if you are confident in your technical knowledge, better do it! If your gadget malfunctions after this process, contact the service center immediately.

In MIUI 9.5 and higher, you only need to edit the files " mixer paths". There is no need to download anything, as you may accidentally replace important system files. Go straight to editing.

For this method to work, you must. If you have not received them yet, then read our instructions for obtaining Root rights on Xiaomi phones.

Editing the mixer_paths_tesha file

To work, you will need any explorer with access to system files (in our example we use ES conductor). We find the item “Root Explorer”, go to it, using the search we look for the file mixer_paths_tesha. Open the editor.

A system code window will open in front of us, we need to find these lines:

The values ​​11 will be highlighted in red, change them to 16, save the file and reboot the device.

If these lines are not found, then we search using the words: HPHL Volume.

Increasing volume on Xiaomi: the easiest way (without root rights)

Due to the fact that some countries have certain restrictions on the level of noise produced, Xiaomi must comply with these laws in order to sell its phones in their territories. Therefore, if after changing the system files nothing has changed, or you want to increase the volume of the speaker without root rights, we recommend using this method.

The instructions are very simple, we only need 2 minutes of time and standard phone settings.

  1. Let's go to settings.
  2. Next, go to “Advanced Settings”.
  3. Now click on “Region”.
  4. We change our region to one of the available ones: North Korea, Taiwan or India.
  5. We check the volume after changing the region, preferably.
  6. If the problem is solved, we adjust the time zone.

Note! If it is stated for your model, it may not work in some regions.

Increase volume on headphones

This method partially repeats the one described above, but now we will change the values ​​for the sound volume in the headphones.

  1. Open Root Explorer, go to the “Root Explorer” line.
  2. Finding the file mixer_paths(path:/vendor/etc/mixer_paths.xml), open it.
  3. Searching for a string .
  4. If you have a European region, then you need to change the value from 72 to 82 ( higher is possible, but changes should be made several points at a time).
  5. After this you need to restart your phone.

If none of the above helps, there is only one way out - the help of a specialist.

A couple of tips:

  1. See what mode you have. It is quite possible that they switched to “Quiet”, “Meeting” by mistake. It is best to set it to “Standard” or “Outdoor”, then vibration is added. Don't use Airplane mode unless necessary. Yes, when you turn it on, there are no ads in applications and unnecessary spam messages, but the volume may deteriorate.
  2. Check if there is contact between the headphones and the device. Since the cause of interference may be a faulty headphone or dirty connectors.
  3. And the simplest thing: set the volume scale to maximum. Volume up button and you're done.

How to increase the volume on Xiaomi on different models

After updating your Xiaomi to MIUI 9, you can increase the volume using any of the methods. Previously, it was possible to download files with settings through recovery, but now it is better to change them using Explorer.

Mi Max 3

If you have global firmware, then there is one quick way. But you need Root and extended recovery - TWRP. Download the file AudioBoostEnable.zip(enter in search and download from 4pda). These are the settings of the Chinese firmware, there are simply no sound restrictions. Everything is set within reason, and the difference in sound is clearly felt. Tested on MIUI 8.6.1.0.

Redmi 3S, 3X

Download the audio mod (also download via 4pda Sound_Mod.zip). Thanks to the collaboration of forum members, lengthy tests and settings, a golden mean in sound was found (tested for headphones). This point can be considered universal, and can be applied even to more serious Xiaomi models.

Redmi 4X, 4A

Go to Google Play, enter the name in the search Sound Booster (Volume Boost), download, customize it to your liking and enjoy the good sound.

This means, as we noted above, the failure is mechanical.

As you can see, improving the sound on Xiaomi phones at home is not always easy. You must have at least minimal technical skills. If you carry out the procedure correctly and carefully, following our instructions, the result will undoubtedly please you.

Almost all phones experience software glitches, the source of which may be in the firmware. To identify them and determine the type of failure, there is a special service menu through which you can test each module in the phone and identify the essence of the problem.

In this article, we will tell you what the xiaomi engineering menu is, login methods, as well as the main functions that may be useful to you.

What is the engineering menu and main functions

These are hidden smartphone settings aimed at testing and correcting errors. These settings are not available in the regular menu, because... inexperienced users may mess up the correctly set parameters, after which the phone may stop ringing, the connection may be lost, etc. Therefore, be very careful not to harm the system.

The engineering menu on the xiaomi redmi 3 phone performs the following functions:

  • Setting the sound in the main speaker;
  • Setting the sound in the conversational speaker;
  • Microphone settings;
  • Setting up networks;
  • Camera setup;
  • Testing GPS operation;
  • IMEI repair;
  • Ability to optimize the system for less battery consumption.

These are not all functions, but rather the main ones that are in greatest demand.

How to enter the engineering menu

Let's look at ways to enter the engineering menu using the example of Xiaomi Redmi note 3 pro. There are only two standard methods. The third option is through applications, which is worth using if standard methods do not work.

Through settings

Note that this method is universal; it is also suitable for Xiaomi redmi 3s. So, let's go to the smartphone settings. Scroll down and tap on “About phone”. We look for the line “Kernel version” and slowly click on it three times. Perhaps the message “You only have to press two more times” will appear at the bottom. In the same way, slowly press two more times.

The “secret settings” look like this (depending on the phone, the view may differ slightly):

Using a special code

Open the dialer and dial the code *#*#6484#*#*. The same thing will appear as above in the screenshot. This code should be suitable for all Xiaomi devices. If nothing happens when you dial this combination, you should try the following codes: *#*#3646633#*#* or *#*#4636#*#*.

On some other models, the engineering menu looks like this:

If you can’t open the engineering menu

If Xiaomi redmi note 3 pro does not enter the engineering menu, then you should use alternative login methods, namely special software. Let's look at two programs that will help you: MTK Engineering and MobileUncle Tools. You can find many more similar applications on your own.

MTK Engineering is a fast and convenient program, it looks like this:

In the Android Testing section there are Android settings, namely:

  • Phone information;
  • Battery information;
  • Usage statistics;
  • Wi-Fi information.

We need the MTK Engineer Mode item - this is the engineering menu itself. The appearance may be slightly different, but the essence will not change.

MobileUncle Tools is a more powerful program than the previous one, in that it additionally allows you to perform many other operations with the system, however, only for devices with MTK processors, which are not found in all Xiaomi devices.

To get started, you need to click “Engineering Mode” and then select “Engineering Menu (MTK)”. It is worth adding that this program requires root rights. Currently, this program has been removed from the Play Market, but it is not difficult to find on the Internet. Since this application is developed by a Chinese author, you may encounter an English or Chinese version.

Conclusion and translation of functions

Finally, we would like to caution you to be careful with your many system settings. If you need to repair or check any module in your phone, you should not immediately change the parameters of the engineering menu yourself; it is better to first look for instructions on our website or on the Internet specifically for your case. For convenience, we have translated all functions (the Xiaomi Redmi Three smartphone was taken as an example).

Xiaomi smartphones have a wide variety of settings, ranging from customization and themes to all kinds of firmware and launchers. In this article we will tell you what the engineering menu is in Xiaomi smartphones, how to enable it and configure various parameters there.

What is the engineering menu in MIUI

The Engineering Menu is a built-in feature in Xiaomi smartphones that allows MIUI users to run a hardware check on their devices. This is to ensure that all hardware components are working as expected. For example, in the engineering menu you can check for dead pixels on the display, adjust the volume, and also calibrate the operation of various sensors. The advantages of this mode are as follows:

  • Easy to use
  • Works on all Xiaomi phones: Redmi and Mi
  • No external hardware components required
  • You can avoid service centers and repair everything yourself

How to get to the engineering menu on Xiaomi

To enter this mode, you just need to open the standard “Phone” application and use the touch keyboard to enter the following combination: *#*#6484#*#* . This should work in most cases. If your phone does not respond, try these combinations.

  • *#*#3646633#*#*
  • *#*#4636#*#*

If this doesn't work, try going to Settings > About the device and click on the kernel version several times in a row. Do this until the menu opens.

Great, you've reached the menu, now we'll tell you about the main features of this utility. Below is how to check your Mi smartphone and how to fix what is not working properly.

How to run a hardware test in the engineering menu

In this menu you will see an item Automatic Test. Click on it, the automatic test will take you through each test of each component separately, including testing sensors, volume, cameras, vibration motor, Bluetooth, Wi-Fi, touch screen, etc., even for simple things like LED indicator and check buttons

When you click on the item Single Item Test(Checking One Item) will show you the names of all the hardware components of the device. If you are having problems with a specific component, such as the speaker and volume, you can select this option and calibrate the setting.

For example, click "WLAN" if you want to test your Wi-Fi module, click "Gyroscope" to test the gyroscope capabilities. Likewise, you can test any hardware component, one at a time, using Single Item Test.

Button Test Report will show you detailed iron test results. This way you can determine if any hardware components are faulty or broken. The test report indicates the failed component as "FAIL" and the functioning component as "PASS". If any test fails, it says "NOT TEST".

SW and WH Version- Software and Hardware Version provides all the information about the version of device software currently running on the device. As well as all the hardware version information along with IMEI numbers if you need to know this information.

Device View contains information about the processor, display panel, battery, Bluetooth and other things along with information about the manufacturers of these components. All this information can also be used to check whether your device is original or counterfeit.

It is worth noting that the engineering menu works on all Xiaomi devices and is a universal way to check equipment for originality and performance.
