Increase the sound on your phone through the engineering menu. Engineering menu in Android phones. Entering the engineering menu

An optimally selected sound volume allows you to hear an important call, watch a movie or listen to music with pleasure. You can adjust the sound on Android separately for applications, notifications, calls and players. The user has several ways to increase the volume, including through the engineering menu - they are described below.

On smartphones and tablets running Android, you can adjust the sound using the volume key. The key is a “rocker” - pressing up increases the volume, and clicking down decreases it. If an application or movie is open at the moment you press the key, the media volume will change, and if the desktop, the call volume will change.

If the sound spontaneously switches to “Quiet”, check your smartphone for viruses. Remove applications that have access to volume control and evaluate the situation. Also check if the “Ring louder in your pocket” mode is enabled. To do this, go to settings, select “Calls - Call louder in your pocket.” If necessary, disable the feature.

You can configure sound settings in the standard settings of your smartphone or tablet:

Go to Settings and select Sound.
Select "Volume".
Use the sliders to adjust the volume values for each type of sound - notifications, calls, applications.
Click "OK" to save the settings.

Depending on the version of Android, the settings item may be called “Melodies and Sound”, Sound, etc.

Setting up the sound of headphones and speakers using phone or tablet applications - instructions

For users for whom the standard sound volume on a smartphone or tablet is not enough, tone amplifier programs have been developed.

Volume+

Volume+ is a program that allows you to increase the volume of Android 2.3 and higher melodies. Works with the device profile, as well as with a headset and hands-free. The developers offer two versions of the program - free and paid. According to reviews, the first increases the volume by 20–30%, the second by 40–50%. The sequence of sound adjustment in the application:

Install the program from Google Play and run it. There are three or four apps with a similar name in Google's storage. The developer of the required one is Meltus.
In the program window, check the box next to Speaker Modifications.
Go to the speaker settings section.
In the Volume Level menu, change the audio level. At the maximum setting there may be distortion, so check the audio quality and reduce the setting if necessary.
In the Bass Enhance menu, adjust the bass level.

To adjust the sound in a headset and hands-free, perform similar actions in the corresponding sections of the menu.

Once setup is complete, the application will save the settings and run in the background. You won't have to adjust the sound after rebooting the gadget.

How to increase the maximum sound level

The engineering menu differs in different smartphone models, but the structure remains similar. Once you enter the menu, you will see settings sections - find the Audio item. The section includes subparagraphs:

Headset mode. Headset volume control.
Normal mode. General settings for smartphone or tablet speakers.
LoudSpeaker Mode. Hands-free mode.
Headset LoudSpeaker mode. Loudspeaker mode when a headset is connected.
Speech Enhancement. Talk mode without connected devices.

For each mode, it is possible to change the volume. Can be configured:

Mic - microphone sensitivity;
Sph - speaker volume;
Media - volume of multimedia playback and sounds in applications;
Ring - call volume;
Sip - Internet call parameters;
FMR - FM radio.

To configure a specific setting, select it from the menu. For example, to optimize the sound of multimedia files, select Media. Below the selection line you will find options to configure - levels and volume values. Complete the setup:

There are 7 volume levels in total, each corresponding to one press of the rocker key. Level 0 is the quietest level, level 7 is the loudest.
Select level 0 and set the acceptable volume for it in the field on the right - no more than 255. Click the Set button to save the settings.
Do similar steps for each level.
Set the maximum volume value for the profile - it will be the same for each level. Click Set.

Rewrite the manufacturer's volume settings before changing them. If you do something wrong, you can always return the volume to default.

Once you've finished setting up your media, move on to the next steps. The volume control method for the microphone, speakers, and headset is the same.

How to increase the quiet volume of a ringtone

To increase the ringer volume, work with the Ring item in Normal Mode. Change the values for each volume level one by one. Don't forget to click Set to save the settings. Remember - when the maximum values are set, the sound quality decreases significantly.

Increase speaker volume (during a call)

If you can't hear the person you're talking to on the phone, try increasing the speaker volume. Go to the Normal Mode section and select Sph. Increase the values for each volume level by 10–20 units. Set the maximum volume as desired.

Change microphone sensitivity

You can set up your device in the same way if the other person can’t hear you. In the Normal Mode section, select Mic and set the sensitivity to be the same for all levels - approximately 240. Save the setting for each level in turn.

Microphone sensitivity when recording video and audio

If you think that videos and audio recordings are not loud enough, go to the LoudSpeaker Mode section in the engineering menu and select Mic. Make the settings in the same way as the previous point.

When the setup is complete, exit the menu and restart your smartphone or tablet. The device activates the new settings.

Tricks to boost sound on Android

An external speaker solves the problem of insufficient volume on a smartphone or tablet when other methods do not help. The speaker is a small device with a 3.5 mm plug that is inserted into the headphone jack or connected via Bluetooth. Cost - from 700 rub.

A lifehack to increase the volume - while playing a video or playing music, position the smartphone with the speaker towards the painted wall. The sound will be reflected from the surface and at the same time amplified.

Is it possible to remove the volume limit?

Android smartphones have a maximum volume limit to protect the device's speakers and users' eardrums. The engineering menu allows you to increase the upper limit - the Max item. Vol. The maximum value is 255 units. It is impossible to set the value higher, and it is not required - otherwise the speakers will not stand it.

If you do not want to access the service menu, use the Volume Unlock application:

Install the program from the Play Store.
Go to the application and activate the Enable Volume Power item.

The program does not remove the limitation, but increases the maximum value.

Test the methods described above to increase the volume and choose the best one for your device. Work with the engineering menu carefully - incorrect settings can lead to problems with the sound of your smartphone or tablet.

Too low speaker volume is something that can seriously ruin your mobile phone experience. After all, no one wants to miss calls because you simply didn’t hear the call. If you have a similar problem, then do not rush to get upset, in this material you will learn how to increase the volume on Android.

The first thing to do is check the sound settings in Android and make sure that the volume is set to maximum. To do this, open Android settings and go to the Sound section. If you have a Samsung smartphone, then you need to first go to the “My Device” tab.

And then open the “Sound” settings section.

After this, you will see a pop-up window with audio settings.

Here you can set the desired volume for ringtones, notifications, system messages, as well as the volume of music, videos, games and other multimedia programs.

How to increase volume on Android using third-party programs

If everything is fine with the volume settings, then you can try using special applications. One such application is . This application allows you to increase the volume in your headphones, the volume of your Bluetooth headset, as well as the volume of your Android smartphone's speakers.

This application is also equipped with various functions to improve the sound. For example, with its help you can enhance low frequencies or add sound effects. There is also a 5-band equalizer with 20 sound settings available.

The application is distributed in two versions: – a paid version of the application with all functions, and also – a free version with a limited set of features. In addition to Volume+, there are other applications that allow you to increase the volume of your Android device, such as Volume Control.

Often in Chinese (and probably not only Chinese) phones based on Android, in the engineering menu there are far from optimal settings for the volume of the speaker, headset (headphones) and microphone; we will look at fixing them in this article.

How to get to the engineering menu of an Android phone

To get to the engineering menu, open the dialer and enter a special code: *#*#3646633#*#*

Also on some versions of Android the command may work *#15963#* and *#*#4636#*#*

If your phone's processor is not MTK, then different options are possible.

Here are the codes known to me for opening the engineering menu on different phones and tablets:

*#*#54298#*#* or *#*#3646633#*#* – smartphones based on MTK processor

*#*#8255#*#* or *#*#4636#*#* –Samsung smartphones

*#*#3424#*#* or *#*#4636#*#* or *#*#8255#*#* – HTC smartphones

*#*#7378423#*#* – Sony smartphones

*#*#3646633#*#* – smartphones TEXET, Fly, Alcatel,

*#*#3338613#*#* or *#*#13411#*#* - smartphones Fly, Alcatel, Philips

*#*#2846579#*#* or *#*#2846579159#*#* – Huawei smartphones

*#*#2237332846633#*#* - devices from Acer

Immediately after entering, the command should disappear and the engineering menu should open. But on some devices you will still need to press the “Call” key

A list of sections of the phone's engineering menu will appear.

Just in case, take a notepad and pen and take note of the settings that were set on your phone before your intervention. You never know, anything can happen.

On my phone (based on an MTK processor), in order to get to the engineering menu I had to install a free utility (program) from Google Play " Mobileuncle MTK Tools“, which opens access to the engineering menu (that is, it works similarly to dialing the magic combination *#*#3646633#*#*).

I am sure that you will also find free applications for other phones there.

Volume settings for the speaker, headset (headphones) and microphone of the phone through the engineering menu

For clarity, let’s briefly look at setting the device’s volume level:

We go into the program or dial the magic combination to enter the engineering menu. Next, in the menu that opens, select the section “ Engineer Mode»

A section will open in which you can select the engineering menu of the Android system (we skip it), and the engineering menu of the phone itself.

We need the phone’s engineering menu, so select the “Engineer Mode (MTK)” section. This point is circled in the figure with a red marker.

A very long menu will open, through which you can get to almost any phone settings. But it’s not enough to get to them, you need to know how to manage them.

Therefore, do not change what you have no idea about.

At worst, write down the parameters that were before your intervention, so that you can return them back later. Let's continue!

Since we are interested in adjusting the sound level, select the “Audio” item, I circled it with a red marker.

And... magic! The menu of interest to us for setting the parameters of the speakers and microphone opens.

Why did we actually go into this menu? Doesn't something work like that out of curiosity? Okay, let's continue to figure it out!

It’s worth stopping here and figuring out what all these menu items mean.

Normal Mode(Settings section in normal or normal mode) – this mode is active when nothing is connected to the smartphone;

Headset Mode(headset mode) – this mode is activated after connecting headphones or external speakers;

Loud Speaker Mode(speaker mode) – it is activated when nothing is connected to the phone or tablet, and you turn on the speakerphone while talking on the phone;

Headset_LoudSpeaker Mode(speaker mode with a headset connected) – this mode is activated if you connect headphones or external speakers to your phone or tablet, and you turn on the speakerphone while talking on the phone;

Speech Enhancement(phone conversation mode) – this mode is activated in the normal mode of telephone conversations, and nothing is connected to it (headset, external speakers) and the speakerphone is not turned on.

Debug Info– it’s not clear why – information on backing up information or debugging it;

Speech Logger– I haven’t fully figured it out, most likely it was logging during negotiations or recording the conversation. If you check the box next to “Enable speech log”, then after the end of the phone call, the corresponding files are created in the root directory of the memory card. Their name and structure take the following form: Day of week_month_year__hour_minutes_seconds (for example, Friday_July_2016__time17_12_53.pcm).

What these files serve and how they can be useful to us is unclear. The /sdcard/VOIP_DebugInfo directory (which is the storage location for files with backup information) is not created automatically; if you create it manually, it will remain empty after the conversation.

Audio logger– used to record sound that supports quick search, playback and saving.

When you enter any of the modes, you will have access to different volume settings (Type). Here is a list of basic settings you need to know:

Sip – settings for Internet calls;
Mic – microphone sensitivity settings;
Sph – earpiece speaker settings (the one we put on our ears);
Sph2 – settings for the second speaker (I don’t have one on my phone);
Sid – skip, if you change these parameters during negotiations on your smartphone or tablet, you can hear yourself instead of your interlocutor;
Media – adjust the multimedia volume level;
Ring – adjust the volume level of the incoming call;
FMR – FM radio volume settings.

Under the settings selection item, a list of volume levels (Level) is available (see figure).

There are usually 7 such levels, from level 0 to level 6. Each such level corresponds to one “click” on the volume rocker of your smartphone or tablet.

Thus, level 0 is the quietest level, and level 6 is the loudest signal level. Please note that each level can be assigned its own values, which are located in the Value is 0~255 cell. They should not go beyond the range from 0 to 255 (the lower the value, the quieter the volume).

To change this parameter, you need to erase the old value in the cell and write a new one, and then press the “Set” button (the one next to the cell) to assign.

Finally, at the bottom you can see the Max Vol section. 0~255 (on my smartphone, for example Max Vol. 0~255, it all depends on the manufacturer). This item sets the maximum volume level; it is the same for all levels.

Dear friends. The names of the items may differ on different models. This is an MTK platform, so be prepared to rack your brain and look for a match in your menu. I have a Jiayu G3 phone.

For me the changes were applied immediately, but someone may need to restart the phone for them to take effect.

Although, it seems like you shouldn’t break anything, and if you don’t like the changes, you can always enter the old value..
But still..
YOU MAKE ALL CHANGES AT YOUR OWN RISK!!! Don't forget to turn on your thinking!

P.S.: I found a font size setting on my phone. It turns out you can increase it MORE!
P.P.S.: if something is still not clear, here is a video on setting up sound in the engineering menu:

Manufacturers of Android smartphones implement and use the engineering menu to test devices. It contains all kinds of tests and device settings that are not available to ordinary users. However, today, knowing the USSD command or downloading the application from PlayMarket, anyone can go to the engineering menu.

Why do you need a hidden engineering menu in Android?

Engineering Menu (Engineering Mode) is essentially a hidden application that developers use to test and set the optimal parameters of a mobile phone or tablet. Specialists check the operation of the sensors and, if necessary, make adjustments to the functioning of system components.

When working with the Android technical menu, be careful - changing some functions leads to malfunctions of the device.

How to enter the menu

To open the menu installed by the manufacturer, activate the dial pad on your smartphone and enter one of the USSD commands presented in the table. After entering the command, the numbers will disappear from the screen, and a menu will open instead.

In the dial pad, enter a combination of numbers and symbols to enter the menu

If the code does not work and you cannot launch the service menu using the standard method, use third-party applications - you can download them on PlayMarket. Recommended programs - “Launch the MTK engineering menu”, Mobileuncle Tools, Shortcut Master.

The manufacturer menu does not work on some device models with Android 4.2 JellyBean (x.x.1, x.x.2), as well as on Android 5.1 Lollipop. The menu is also invalid when the Cyanogen Mod firmware is installed. In Android 4.4.2, when you reboot, changes made in the application are reset.

“Launch the MTK engineering menu”

The application allows you to open and configure the engineering menu without typing digital commands. Works correctly on MediaTek processors (MT6577, MT6589, etc.) and Android systems 2.x, 3.x, 4.x, 5.x. According to user reviews, the program successfully performs its functions, but after rebooting the smartphone, the settings made using the application are reset.

Mobileuncle Tools program

The functionality of the application is similar to the previous one, but, in addition to accessing the engineering menu, the user has the opportunity to view information about the screen, sensor and device memory, as well as update the firmware, restore the IMEI number and improve GPS. For stable operation, root rights are required.

To enter the engineering menu, select Engineer Mode

Shortcut Master utility

The Shortcut Master program is designed to work with shortcuts and system applications: creating, searching, deleting. It does not have a direct function for entering the engineering menu. But with its help you can view the list of secret commands operating on your device. And by clicking on the name of the command, you will see a drop-down menu in which there will be an item “execute”. Convenient and does not require unnecessary actions.

In the program, call up the additional menu and select Secret code explorer to see a list of codes

Root rights to access the engineering menu

To get to the service menu on some versions of Android, the user must have superuser rights (root). You can obtain rights using specialized applications: Farmaroot, UniversalAndRoot, Romaster SU and others. To get Root access to your device using Farmaroot:

Install and run the program. Link to Google Play: https://play.google.com/store/apps/details?id=com.farmaapps.filemanager&hl=ru.
If the application supports installing root rights on your device, then on the screen you will see a list of possible actions, among them - “Get root”. Select this item.
Choose one of the preset root methods.
The program will begin installation.
At the end of the procedure, you will see a message about the successful installation of root access.

Instructions for obtaining root access through the Farmaroot application

Possible problems and solutions:

the application closed mid-installation - restart the device and try again;
root rights are not installed - try installing using a different method (select a new exploit in the application).

What can be configured in the menu

The appearance of the engineering mode and the ability to adjust parameters may vary depending on the tablet or smartphone model. In the menu, users most often adjust the sound, change camera settings and use recovery mode. The parameters for adjustment and the procedure are given below. Be careful - the names of menu items may differ in different device models! You act at your own risk.

Audio: Increase volume level

If your phone does not ring loudly enough, find the Audio section in the engineering menu and go to LoudSpeaker Mode. Select Ring. For each signal level (level 1–6), change the values - set the numbers in ascending order, from 120 to 200. Increase the value in the Max item. Vol - maximum 200. Press the SET button to save the settings.

Sequentially change the maximum volume values for each level

Audio: Increase phone call volume

To enhance the speaker tone for conversations, in the Audio service menu section, select Normal mode and open the Sph item. Set the values for signal levels (level 1–6) from 100 to 150, and the number for Max. Vol. – up to 160.

By adjusting the speaker volume, you will be able to hear your interlocutor better during a call.

To increase the sensitivity of the microphone, go to the menu Audio - Normal mode - Mic. For each level, assign the same microphone sensitivity values, for example, 200. Press the SET button, reboot and check whether the other party can hear you better.

Increased microphone sensitivity will allow the other person to hear you better

Battery: Disable unused frequencies

Smartphones quickly drain battery life running applications, maintaining cellular communications, and network connections. Using the engineering menu you can increase the battery life.

Modern devices scan several GSM frequencies - 900/1800 MHz and 850/1900 MHz. In Russia there is a 900/1800 MHz pair, which means there is no need to scan the network at other frequencies. The radio signal for the second pair can be turned off, which will significantly save the charge level.

In Engineer Mode, open Band Mode. Disable unused frequencies by unchecking the corresponding items - PCS1900 and GSM850. If the device supports two SIM cards, open the SIM1 and SIM2 items one by one and perform the indicated steps in each. Press the SET button to save the settings.

Disabled frequencies save battery power

If your smartphone and SIM card operate in 3G networks, disable the networks that are not used in Russia: WCDMA-PCS 1900, WCDMA-800, WCDMA-CLR-850. Press the SET button again.

You can enable scanning of disabled networks by returning to the same menu and checking the boxes.

Camera: photo and video settings

By default, Android devices save pictures in JPEG format. Meanwhile, photographers prefer to shoot and process material in RAW to gain more editing options. The technical menu allows you to select the desired image format.

Find Camera in the menu and select Capture Type. Set the photo format to RAW and press SET. Also in the Camera menu you can increase the size of pictures, set the ISO value, enable shooting in HDR for higher photo detail, and set the frame rate for videos. After changing each parameter, remember to press SET to save the settings.

Recovery Mode

Recovery Mode is an analogue of Bios on a computer, allows you to manage the device without logging into the Android system. Recovery mode features:

resetting settings to standard;
firmware update;
access to root rights;
creating a backup copy of the OS;
removal of personal data from the system.

In Recovery Mode, do not perform an action if you are not sure what it will lead to. Some commands may harm the device and system.

If the settings are not saved

Users who have access to the technical menu complain that the parameters changed in it are not activated or are reset when the device is restarted.

To activate the settings after changing the parameters, tap on the SET button at the bottom of the screen. If the parameters are reset after rebooting the device, try accessing the technical menu not through the application, but using a digital command.

After setting the settings, do not forget to press the SET button

Service codes for Android devices

In addition to the technical menu, secret USSD codes - combinations of numbers and symbols, which the user types by typing to perform an action, allow you to control the functionality of Android smartphones. Secret codes for different devices are given in the table.

If for some reason the service code did not work, do not worry - install and run the Secret Codes application (Link on Google Play: https://play.google.com/store/apps/details?id=fr.simon.marquis. secretcodes&hl=ru). The program will analyze the combinations active in the device and offer you a list. You can activate the combination directly in the application with one click on the name.

There are many ways to improve your Android mobile device using the engineering menu. The menu structure differs in different device models, but the basic functionality is preserved everywhere. When opening and changing parameters in the service section, be careful - some commands lead to system failures and damage to the device.

The engineering menu on Android devices is a special “built-in” application into the operating system that allows you to fine-tune the device. This is necessary to debug the operation of the hardware and, of course, the software. But often users want to change some settings at their own discretion. In this case, the question arises of how to enter the Android engineering menu. This can be done using special service codes or third-party software.

Developer menu: what are the options?

Settings and menu design on Android devices may vary depending on the phone manufacturer. In general, users resort to using the engineering menu for the following reasons:

Setting up audio on the phone (ringer volume, interlocutor’s voice during a conversation);
Changing camera settings;
Using recovery mode;
Setting microphone sensitivity;
Disabling unused frequencies to save phone battery;
Obtaining information about the device's MAC address;
Setting up Bluetooth and Wi-Fi.

The Android engineering menu provides the user with almost limitless possibilities. But you should always remember that only advanced users can use it. Changing some settings may lead to incorrect operation of your smartphone or tablet. If you don't know what each menu item directly does, simply leave it alone.

The developer mode includes setting up Hardware Testing equipment and also contains the following items:

Audio – volume control in the phone speakers.
Camera – allows you to configure various camera parameters (image size, type, etc.).
Diving current camera shows the current of the camera.
CPU Stress Test performs a test load on the central processor.
De-sense is a device manager that manages configuration parameters.
Display – setting the frequency of the outgoing signal.
IO – setting up input/output operations.
Memory – key information about memory.
Power – information about the battery.
SD Card Test - testing a memory card.
TouchScreen – setting up the touch screen, checking sensitivity.
USB - testing the operation of the USB port on your phone.

In the Connectivity tab you can get information about devices that work with the outside world. These include Bluetooth, Wi-Fi and FM module. The Log and Debugging tab allows you to view the battery log, set the debugger level and run a special MTK log. In the Others tab you can change fonts, as well as view the temperature of the processor and battery.

Entering the menu: using code combinations

To enter the engineering menu as quickly and easily as possible, you will need special engineering codes. Each manufacturer has its own combination, which opens access to the engineering menu in Android.

To enter the menu you need to:

In most cases, this technique allows you to open the service menu. Below are some combinations for the most popular phones:

Models from HTC - *#*#3424#*#*, *#*#4636#*#* or *#*#8255#*#*;
Samsung devices - *#*#197328640#*#* or *#*#8255#*#*;
Sony smartphones - *#*#3646633#*#*, *#*#7378423#*#* or *#*#3649547#*#*;
Huawei phones - *#*#2846579#*#* or *#*#14789632#*#*;
Mobile from ZTE - *#*#4636#*#*.

There is also a universal code that is suitable for most smartphones and tablets running on an MTK processor. You can look in the specifications of your device to see what processor you have installed. If this is a MediaTek (MTK) product, then try using the combination *#*#54298#*#* or *#*#3646633#*#*.

If it works, you will see the developer menu in front of you. Some engineering codes for Android do not work in operating versions 4.2.1 and 4.2.2.

Using Third Party Applications

How to enter the engineering menu on Android if the Android codes do not work? There is a way. To enter the engineering menu, you will need one of the applications that will allow you to enter developer mode without entering a combination. There are several similar programs in the official Google Play store. One of them is “Launch the MTK engineering menu”.

To use it, you need:

Go to the Play Market and enter the name of the program in the search bar.
Download and install it.
Launch on your phone.

After that, you will see a couple of tabs with different settings.

The application allows you to perform various tests (for example, a processor stress test), obtain information about the modem or memory, and much more. You can also make changes to the hardware. To do this, you just need to open the appropriate sections and configure the settings. In this case, the phone will be on all the time.

An alternative option is the Mobileuncle tools program. You can download it on the Internet. Install the application, and then go to the “Engineer Mode” submenu. Almost all developer menu items will be available in it.

Now you know how to enable Android developer mode. It will help you quickly make the necessary settings or monitor individual components of your smartphone.

Smartphones and tablets running Android have many interesting features hidden from prying eyes.

Why are they hidden? Firstly, so that an inexperienced user does not break anything, and secondly, they are needed in especially rare cases and are not used regularly. Today we will talk about the engineering menu.

What is it and why is it needed?

We are talking about a special program that developers use at the final stage of configuring the software platform of a mobile device. With its help, they make final changes to the operation of the device, check the functioning of various sensors and test system components. Hidden functionality is also used to obtain a large amount of system information and conduct various tests (about 25 pieces).

Attention! This section is intended for experienced users who bear full responsibility for the consequences.

The engineering menu is available on smartphones and tablets running on a MediaTek processor. On the Qualcomm chipset it is either reduced or absent altogether.

How to open the engineering menu?

To enter the engineering menu, you need to enter a special command in the dialing application: *#*#3646633#*#*. On some versions the code *#*#4636#*#* or *#15963#* may work.

If the code did not work or you do not have a dialing application (relevant for tablets that do not support calls), the MobileUncle Tools or MTK Engineering applications, which can be downloaded for free via Google Play, will help.

Advanced users of modern smartphones and tablets use the numerous functions that the Android engineering menu has. It allows you to obtain information about the mac address, check or configure the operation of Wi-Fi, Bluetooth, update the software of the camera, speakers. Very often, using such a menu you can improve the sound on your device and make other fine adjustments. For example, return the original Google account settings, specify settings for blocking and turning off the device, and set settings that allow you to create a backup copy of important information. Before entering the engineering menu, you need to understand that rash actions can lead to a malfunction of the device. It is advisable for the user to remember what changes were made to the system in order, if necessary, to return all settings to their previous state.

How to enter the engineering menu using the standard capabilities of the device?

The list of functionality can be opened by typing a specific combination of characters in the device call window. The Android engineering menu code varies depending on the brand of phone or tablet. Each manufacturer sets its own combination. Such information is usually indicated in the instructions for the phone and on official websites. Users of modern devices usually have no difficulty finding the required code.

Below we provide a table of the most common combinations. It is not recommended to use them unless your device is one of the listed brands.

The developers do not recommend executing such commands without certain knowledge and experience. But often only this method helps to quickly solve a number of problems related to returning the device to its original state, obtaining additional information about the device. The engineering menu is presented in English, which makes it understandable for most users.

Using additional programs

It is not always possible to find out the combination that is suitable directly for your device. In such situations, you can install special software on your mobile device, which will allow you to open a list of the functionality of your smartphone or tablet with a few clicks. It is publicly available for different versions of Android and device models.

The program for entering the Android engineering menu can be installed via a USB connection to a personal computer or laptop. One of them is called Mediatek Engineer Mode. It is a file EnMode.apk, which must be transferred to the device memory and installed in the usual way. This program is suitable for devices operating on the MTK processor. The user has the opportunity to download free and paid versions of the software.

In the Google Play store you can download the Mobileuncle MTK Tools utility. It is designed for smartphones and tablets running Android 2.1. and later versions. The description says that such a utility is also only suitable for devices equipped with an MTK processor.

The Mobileuncle Tools program is suitable for owners. There are other utilities, for example, Shortcut Master, MTK engineering menu, launching MTK engineering menu. Before installing them, we recommend that you read the application rating, reviews from other users, and also check your device for compatibility.

Setting up optimal sound by opening the engineering menu

One of the most common reasons why users look for information on how to enter the engineering menu is the need to fine-tune the sound. The following situations may occur:

Poor audibility when the speakerphone is on
Sudden changes in the sound of an incoming call while listening to audio
Insufficient signal volume
Quiet sounds while recording video
Quiet operation of the headset and microphone.

This is just a small list of installed settings that can be changed through the engineering menu of a modern mobile device. Sound settings are done through the Audio section, which is displayed immediately after entering the menu. Then various tabs will appear on the screen, such as Headset Mode. This tab allows you to set sound parameters that are activated when you connect a headset. Normal Mode sets the sound in the normal state of the mobile device (without connecting headphones or speakers).

LoudSpeaker Mode tab, which are activated when the loudspeaker is turned on. Headset LoudSpeaker Mode allows you to make settings for the active loudspeaker mode while a headset is connected to it. The Speech Enhancement tab provides settings that come into play when communicating over a mobile network.

In any of the modes, you can fine-tune the microphone or increase the volume (see table).

The volume of any sound parameter has seven levels - from 0 to 6. The higher the value, the louder your device will sound. We do not recommend setting the maximum settings, as this promotes faster performance. In many devices, setting the volume to maximum can result in unpleasant noise.

The engineering menu is a mechanism for fine-tuning mobile devices operating on the Android platform

Often in Chinese (and probably not only Chinese) phones based on Android in the engineering menu there are far from optimal volume settings for the speaker, headset (headphones) and...

On the pages of our website we have already described how to do it on an Android device. It may be needed if you need to change any parameters, including the volume of your smartphone. Next, you will find out what needs to be changed and where.

We immediately draw your attention to the fact that you perform all actions at your own peril and risk, the editors do not bear responsibility for your actions, since the likelihood of clicking the wrong way or adjusting something incorrectly, although small, is still there. Be careful. If you have never encountered an engineering menu before, ask someone who has already dealt with adjusting the volume programmatically to help you!

Instructions

First you need to get into the engineering menu. We will show an example on a smartphone that is based on an MTK (MediaTek) processor. On your smartphone, dial *#*#3646633#*#* (the last character is not shown in the screenshot, since the engineering menu immediately opens and you won’t be able to take a screenshot).

Codes for entering the engineering menu on other devices (operability has not been tested):

If you need to turn up the speaker volume, select Normal Mode.

Sip - volume of Internet calls.

Mic - microphone volume.

Sph - speaker volume.

Sph2 is the second conversational speaker.

Sid - cannot be touched, since problems may occur if this parameter is changed.

Media – playback volume of media files.

Let's say you selected the Media item. See the numbers in the image below? Write them down on a piece of paper or take a screenshot! They may be needed to restore sound if something goes wrong.

In the Value column, you can write the value yourself, or you can click on Level and select one of the levels, for example, Level 2. To save, click Set.

Please note that Value can be set in the range from 0 to 255. It is not recommended to insert the maximum; the speaker may wheeze and quickly fail. Using the trial method, select the optimal value yourself. Just don't overdo it and ruin your device! Item Max Vol. do not touch.

Many smartphone users need to increase the sound level on the device. This may be due to either the maximum volume of the phone being too low or due to some kind of breakdown. In this article we will look at the main methods that allow you to perform all sorts of manipulations on the sound of your gadget.

In total, there are three main methods for manipulating the sound level of a smartphone, there is one more, but it is not applicable to all devices. In any case, each user will find a suitable option for themselves.

Method 1: Standard volume increase

This method is known to all phone users. It consists of using the hardware volume up and down buttons. As a rule, they are located on the side panel of the mobile device.

When you press one of these buttons, a characteristic menu for changing the sound level will appear at the top of the phone screen.

As you know, the sound of smartphones is divided into several categories: calls, multimedia and alarm. Pressing the hardware buttons changes the type of sound that is currently being used. In other words, if any video is played, the audio of the media will change.

It is also possible to adjust all types of sound. To do this, when increasing the volume level, click on the special arrow - as a result, a full list of sounds will open.

To change sound levels, move the sliders around the screen using regular taps.

Method 2: Settings

If the hardware buttons for adjusting the volume level break down, you can perform the same steps as described above using the settings. To do this, follow the algorithm:

Method 3: Special Applications

There are cases when it is not possible to use the first methods or they are not suitable. This applies to situations where the maximum sound level that can be achieved in this way is not satisfactory to the user. Then third-party software comes to the rescue, presented in a fairly wide range on the Play Market.

Some manufacturers have such programs built into the standard configuration of the device. Therefore, it is not always necessary to download them. Directly in this article, as an example, we will look at the process of increasing the sound level using the free Volume Booster GOODEV application.

Method 3: Engineering menu

Not many people know that almost any smartphone has a secret menu that allows you to perform some manipulations on the mobile device, including adjusting the sound. It is called engineering and was created for developers to finalize the device settings.

First you need to get into this menu. Open the phone number dialer and enter the appropriate code. This combination differs for devices from different manufacturers.

Manufacturer	Codes
Samsung	##197328640##
	##8255##
	##4636##
Lenovo	####1111#
	####537999#

Asus	#15963#
	##3646633##

Sony	##3646633##
	##3649547##
	##7378423##
HTC	##8255##
	##3424##
	##4636##
Philips, ZTE, Motorola	##13411##
	##3338613##
	##4636##
Acer	##2237332846633##
LG	3845#*855#
Huawei	##14789632##
Huawei	##2846579##
Alcatel, Fly, Texet	##3646633##
Chinese manufacturers (Xiaomi, Meizu, etc.)	##54298##
Chinese manufacturers (Xiaomi, Meizu, etc.)	##3646633##

After selecting the correct code, the engineering menu will open. Use swipes to go to the section "Hardware Testing" and tap on the item "Audio".

Be careful when working in the engineering menu! Any incorrect setting can seriously affect the performance of your device for the worse. Therefore, try to adhere to the algorithm presented below as much as possible.

There are several sound modes in this section, and each can be customized:
- Normal Mode - normal sound playback mode without using headphones and other things;
- Headset Mode — mode of operation with connected headphones;
- LoudSpeaker Mode - speakerphone;
- Headset_LoudSpeaker Mode - speakerphone with headphones;
- Speech Enhancement - conversation mode with an interlocutor.
Go to the settings of the required mode. In the points marked in the screenshot, you can increase the current volume level, as well as the maximum allowable one.

Method 4: Installing the patch

For many smartphones, enthusiasts have developed special patches, the installation of which allows you to both improve the quality of the reproduced sound and simply increase the playback volume. However, such patches are not so easy to find and install, so it is better for inexperienced users not to take on this matter at all.
