Some smartphone owners complain that they have difficulty hearing the interlocutor, the music is played quietly through the speaker. There are several ways how you can increase the speaker volume on Android. The volume swing is not the only possible method.

Smartphone owners who can hardly distinguish the words of the interlocutor during conversations will be helped by information on how to increase the volume on Android through the engineering menu. In it, you can adjust the volume of the earpiece, headphones.

Initially, the engineering menu is hidden from users. This is explained by the fact that it is necessary only for experienced smartphone owners who fully assume responsibility for possible problems with an electronic device.

Engineering menu available only for owners of smartphones with MediaTek processor. To activate it, there are special codes that may differ depending on the brand of the device.

Entering codes is required as a regular number or USSD request... There is another way how you can call the engineering menu - using special applications.

1. The most popular is MTK Engineering Mode.
2. There is one more free app - “Launching the engineering menu of MTK”.

The choice of the method will practically not affect the algorithm of actions, how to increase the volume of the speakers. After entering the engineering menu, you need to enter the MTK Settings section, then select Hardware Testing Audio. This will open a list of 8 categories. Of these, 5 are categories for increasing or decreasing the volume of sounds.

1. Normal mode. In it, the phone works constantly when no peripheral devices are connected to it.
2. Headset mode, it is activated when you connect speakers or headphones.
3. Hands-free mode, the android starts using it when nothing is connected to the smartphone and the user switches to the speaker mode when making a call.
4. Hands-free headphone mode. The activation of the mode occurs when a person enters the loudspeaker mode with headphones connected to an electronic device.
5. The volume during a call. Its activation occurs when a person is talking to someone in the normal mode and no additional devices are connected to the phone.

In any of the above categories, when you select them, several sections will open.

1. Microphone (Mic)
2. The first and, in some smartphones, the second hearing speaker. (Sph, Sph2)
3. Sid - it is not recommended to change the values \u200b\u200bof this parameter, otherwise you can achieve the effect when the person during the conversation will hear himself and not the interlocutor.
4. Regulation of multimedia. (Media)
5. Volume control for incoming calls. (Ring)
6. Some smartphones have a radio volume setting. (FMR)

Examples of

For example, if the interlocutor practically does not hear you, you need to increase the microphone volume.

To do this, select Mic and the maximum Level, which denotes the maximum step of the volume swing, then change the values \u200b\u200bin the Value section, thereby increasing the microphone volume. After that press Set. If the Setting success window appears, the values \u200b\u200bhave been changed and you can test them.

If a person's smartphone does not have a high volume of incoming calls, it is necessary to do the following. You will need to go to the engineering menu of the electronic device, go to the Audio section, then go to LoudSpeaker and select the Ring value. After that, for each step of the volume swing, you need to increase the values. It is not recommended to set the maximum, for example, with a maximum of 160, it is advisable to set no more than 156. Otherwise, the speaker will emit wheezing and noises when you call.

Finally

After any changes to the Value values, do not forget about the Set button, otherwise the actions will not be fixed and applied. Also, some smartphones, after applying new settings, need to be rebooted and only then test the new values.

Before any changes experienced users smartphones recommend rewriting the standard values. This will allow you to return everything to its place in case of an unsuccessful smartphone volume setting.

Many devices running Android OS are additionally equipped with a special environment - the engineering menu. With its help, the user has the opportunity to test all the sensors and modules of the mobile device, as well as to adjust certain parameters of the gadget for his more comfortable use. In Samsung phones, Engineering Mode is hidden in the system by default. And in different models, the entrance to it is performed differently. And the functionality of this area may also differ. Let's look at how to enter the engineering menu on Samsung Galaxy A5, Galaxy S6, J3 and other smartphones from the Galaxy line.

Where to find the engineering menu on Samsung Galaxy

The main purpose of Engineering Mode is to fully test mobile devices at the final stage of their production. This environment was originally developed for debuggers for smartphones and tablets, but today anyone can use it. The main thing is to know how to open the technical mode on Galax.

You can enter the engineering menu using a special combination (USSD code), which is registered in the dial pad. At the same time, these commands may differ in different phone models:

• in Samsung J7 and J1, the actual combination is * # * # 0011 #;
• for Samsung Galaxy A5, Galaxy S5, Galaxy S6 dial * # * # 8255 # * # * or * # * # 197328640 # * # *;
• on Samsung Galaxy A3 the code is * # * # 9646633 # * # *;
• for Samsung Galaxy S3 - * # * # 0 # * # *;
• in Samsung Galaxy S7 Edge - * # * # 8255 # * # * or * # * # 4636 # * # *.

On other devices from the Galaxy line, you can use the service combinations * # * # 4636 # * # *, * # * # 8255 # * # * or * # * # 3646633 # * # *.

If you can't open the engineering menu using the above commands, you can resort to one of the programs developed specifically for this purpose (EngineerMode, Mobileuncle Tools, Shortcut Master, etc.). To start the technical mode, just install and run one of the utilities. After that, it will automatically enter Engineering Mode.

All applications for opening the engineering menu work only with MTK processors (MT6573, MT6577, MT6589, etc.) and with some Exyon chips. For phones equipped with a Qualcomm CPU (such as Samsung Galaxy A5), this software will be useless.

The main features of the engineering menu on Samsung Galaxy

Having figured out how to enter the engineering menu on Samsung, we will consider its main features. A complete Engineering Mode for MTK chips is equipped with a large number of tools with which you can make a complete diagnosis and precise tuning of Samsung in many parameters.

However, many smartphones have a stripped-down version of the technical mode, which slightly reduces its functionality. And in mobile devices based on the Qualcomm processor, through the engineering menu, you can only view information about some modules and perform small tests of the main elements of the phone (display, modem, SIM cards and battery).

On Samsung Galaxy A5 and Galaxy S6, the main sections of the engineering menu are:

1. Telephony (Telephony);
2. Wireless interfaces (Connectivity);
3. Testing mode (Hardware Testing).

In the Telephony tab, the user can:

The Connectivity section is intended for diagnostics and configuration of Wi-Fi, Bluetooth and FM wireless modules. It is not recommended to change anything here, as this can lead to the failure of the smartphone.

The most popular engineering menu tab is Hardware Testing. This is where you can test the performance of the processor, battery, speakers, camera, display and GPS module. This area allows you to make a complete diagnosis of Samsung at the time of purchase and identify possible product malfunctions.

In smartphones and tablets based on the Android operating system, there is a so-called engineering menu, in which are hidden additional settings devices. The settings are usually intended for specialists. However, if desired, a simple user can also use them, for example, to increase the sound on their smartphone.

How to enter the engineering menu? Let's show an example on a smartphone based on an MTK processor (MediaTek).

Open the Phone app.

Dial the following combination - * # * # 3646633 # * # *. The screenshot below lacks a symbol at the end, because when you enter a full combination, the engineering menu immediately opens. If nothing opens for you, try pressing the call button.

The engineering menu has opened in front of you.

Here you will see many different items and parameters, many of which can be changed.

It is worth changing the parameters only if you know exactly what you are doing. If you don't know, it's better not to touch anything in the engineering menu at all - in order to avoid problems.

You can also download an application for MTK. IN Google play Market search mtk engineering mode and you will see many applications that support the engineering menu. The application works only for devices based on the MediaTek processor.

On Samsung Galaxy, the engineering menu is opened by typing the command * # 0011 #. In front of you, you will see this:

To use, press the "Menu" button on your smartphone and select Back.

If the code doesn't work, and in a standard way the service menu cannot be launched, use third-party applications - you can download them on PlayMarket. Recommended programs - "Start engineering menu MTK", Mobileuncle Tools, Shortcut Master.

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

"Launching the engineering menu of MTK"

The application allows you to open and configure the engineering menu without typing digital commands. Works correctly on MediaTek processors (МТ6577, МТ6589, etc.) and Android 2.x, 3.x, 4.x, 5.x systems. According to user reviews, the program successfully performs its functions, but after restarting 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 can view information about the screen, sensor and device memory, as well as update the firmware, restore the IMEI number and improve GPS. Root rights are required for stable operation.

Shortcut Master Utility

Shortcut Master is designed to work with shortcuts and system applications: create, search, delete. There is no direct function for entering the engineering menu. But with its help you can view a 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.

Root rights to access the engineering menu

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

Install and run the program. Link in Google Play: https://play.google.com/store/apps/details?id\u003dcom.farmaapps.filemanager&hl\u003dru.

If the application supports the installation of 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 predefined root methods.

The program will start installing.

At the end of the procedure, you will see a message about the successful installing root access.

Possible problems and solutions:

the application closed in the middle of the installation - restart the device and try again;

root rights were not installed - try installing it 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 options for adjusting the parameters may differ depending on the tablet or smartphone model. In the menu, users most often adjust the sound, change the camera settings, and use the recovery mode. The parameters for adjustment and the procedure for action are shown below. Be careful - the names of the menu items may differ in different models devices! You act at your own risk.

Audio: boost volume

If your phone is not ringing 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 \u200b\u200b- set the numbers in ascending order, from 120 to 200. Increase the value in the Max. Vol - maximum 200. Press the SET button to save the settings.

Audio: Increase the volume of a telephone conversation

Battery: cut off unused frequencies

Smartphones quickly drain battery life for running applications, maintaining cellular communication 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. A pair of 900/1800 MHz operates in Russia, 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 items SIM1 and SIM2 in turn and follow the steps indicated in each. Press the SET button to save the settings.

If your smartphone and SIM card work in 3G networks, disconnect 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 snapshots to jPEG format... In the meantime, photographers prefer to shoot and process their footage in RAW for more editing options. The technical menu allows you to select the desired picture 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 images, set the ISO value, enable shooting in HDR for higher details of the photo, set the frame rate for video. After changing each parameter, remember to press SET to save the settings.

Recovery mode

Recovery Mode - analogue of Bios on a computer, allows you to control the device without entering android system... Recovery Mode Features:

resetting the settings to standard;

firmware update;

access to root rights;

creature backup OS;

removal of personal data from the system.

In Recovery Mode, do not perform an action unless you are sure of what it will lead to. Some commands can damage the device and the 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 the SET button at the bottom of the screen. If the parameters are reset after restarting the device, try to enter the technical menu not through the application, but using a digital command.

Service codes for devices on Android

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

Table: list of secret commands for Android

If for some reason the service code didn't work, don't be discouraged - install and run the Secret Codes app (Google Play link: https://play.google.com/store/apps/details?id\u003dfr.simon.marquis. secretcodes & hl \u003d ru). The program will analyze the combinations operating 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 mobile device on Android 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 device breakdown.
