Sony xperia engineering menu team. Android service codes and useful key combinations on Sony Xperia

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:

1. Install and run the program. Link to Google Play: https://play.google.com/store/apps/details?id=com.farmaapps.filemanager&hl=ru.
2. 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.
3. Choose one of the preset root methods.
4. The program will begin installation.
5. 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 the camera settings and use the 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, it 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.

Table: list of secret commands for Android

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).

Share with your friends! Not many people know about the existence of a menu in the Android OS with advanced device settings - engineering menu
. And someone knows, but doesn’t know how to enter it and what to do with it.

In this article we will show how to enter the engineering menu and some of its capabilities.

You can enter the engineering menu simply by entering a special command (but I must add that this method does not work on all versions of Android and not on all devices) *#*#3646633#*#*

Command to enter the engineering menu: *#15963#* Also on some versions of Android the command may work*#*#4636#*#*

And

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

If this method does not have any effect, you can use an alternative! And it consists of installing the program (which, by the way, is freely available on Google Play) " 2.4.0"

Mobileuncle MTK Tools*#*#3646633#*#*)

There are a lot of settings there! There is huge scope for experimentation! Almost EVERYTHING can be debugged and adjusted!

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

Go to the program ---> select the "Engineer Mode" section

Because We are interested in adjusting the sound level, select ---> "Audio"

And voila, the menu we are interested in opens.

Max Vol - the same for the entire subsection, as a rule, it is set to 150 (you can change 0-160 - it changes if you select the Media item in the subsection).

If in some submenu, for example, Audio - Normal - Sph, the general level is not available for regulation, then enter another submenu, for example, Audio - Normal - Media - there will be an opportunity to adjust the general volume level.

Sub-items:
Sph - volume levels during telephone conversations,
Mic - microphone sensitivity levels,
Ring - ringer volume,
Media - volume when playing music, movies, and games.

Ring volume levels are set in Audio - LoudSpeaker - Ring
Max Vol = 150
Levels: 120 130 145 160 180 200 (starts to wheeze more)

Phone speaker conversation volume levels in Audio - Normal - Sph
Max Vol = 150
Levels: 100 120 130 135 140 145 150

Microphone conversation volume levels in Audio - Normal - Mic
Levels: 100 172 172 172 172 172 172

Media volume levels are set in Audio - LoudSpeaker - Media

Levels: 110 130 160 190 210 230 250

All the same can be configured for the Headphone mode, by analogy:

Speakerphone volume levels are set in Audio - LoudSpeaker - Sph
Max Vol = 150 (it is the same for the entire section)
Levels: 80 100 110 120 130 140 150 (more wheezing starts)

Now all volumes are adjusted within adequate ranges.
If you are not satisfied with the volume levels, you can set your values ​​(the higher the value, the greater the volume when adjusting with the volume keys, or the greater the sensitivity of the microphone)

By analogy, you can configure most sections! Experiment!

Probably many smartphone owners have encountered volume problems. For example, I was not happy with two things. The first is the quiet sound of the speaker when there is an incoming call, and the second is the very loud sound in the headphones when there is an incoming call.

A little about how Android controls volume

If no headset is connected to your gadget (headphones, hands-free, etc.), then the volume settings will be the same, but as soon as you connect the headset, the settings will be different. For a general understanding, I will tell you a few examples.

Example 1. You listen to music on your phone, turn on the loud speaker at full power, and when you connect a headset to it and turn on the loud speaker again, the volume may differ (it can be louder or lower, depending on what model of phone or firmware version).

Example 2. You are watching a movie with headphones, the volume (meaning the multimedia volume) is set to 40% and then after a while you have an incoming call, then the volume in the headphones will change to the general volume, in which case you can get a powerful sound shock to your ears. Believe me, I jumped off the couch more than once in such cases, the fact is that the programmers did not set up the volume modes well.

Example 3. You're on a call and need to switch to speakerphone mode, and you notice that the speaker isn't as loud (or vice versa) as when listening to music; or your partner has become difficult to hear you, this is because in different modes the microphone may have different sensitivity. Also, when you connect a headset in the same situation and turn on the speakerphone mode, the settings are different again. This is how Android controls volume.

Let's learn the theory of the engineering menu

So let's look at what and how you can do if you tinker a little with the “Engineering Menu”.

Before making any changes, we recommend that you read the entire article, understand it, and then experiment. Also, take a piece of paper and write down all the default values ​​in case something goes wrong. You can launch the engineering menu using a telephone dialer: enter the following combinations on it (Fig. 1):

picture 1

*#*#54298#*#* or *#*#3646633#*#* or *#*#83781#*#* – smartphones based on MTK processor

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

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

*#*#7378423#*#* – Sony smartphones

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

*#*#2846579#*#* – Huawei smartphones

Congratulations, you have entered the engineering menu (Fig. 2). Keep in mind that the menu structure on different phones may differ slightly in structure. Find the “Audio” section and go into it. After logging in, we see a bunch of unknown lines (modes) (Fig. 3). Here's what these modes mean in Android:

Figure 2 Figure 3

— 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 smart phone, and you turn on the speakerphone while talking on the phone;

— Headset_LoudSpeaker Mode(speaker mode with a headset connected) – this mode is activated when you connect headphones or external speakers to the smart phone, 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.

It’s best not to poke your nose into the last three sections:

— Debug Info– it’s not clear why – info 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 chatter. 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: Wed_Jun_2014__07_02_23.vm (Wednesday_July_2014__time07_02_23.vm).

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– good software for recording sound that supports quick search, playback and saving.

If you approach these modes wisely, you can adjust the volume of Android smartphones or tablets the way you want. When you enter any of the modes, different volume settings (Type) will become available to your view. Here is a list of the basic settings you need to know (Fig. 4):

figure 4

—Sip– settings for Internet calls;

— Mic– microphone sensitivity settings;

— Sph– settings for the earpiece speaker (the one we put on our ears);

— Sph2– settings for the second speaker (I don’t have one);

— Sid– skip, if you change these parameters during conversations on your smartphone or tablet, you can hear yourself instead of your interlocutor;

— Media– adjusting the multimedia volume level;

— Ring– adjusting the volume level of the incoming call;

— FMR– FM radio volume settings.

Next, under the settings selection item, we have access to a list of volume levels (Level) (Fig. 5). For a better understanding, there are 7 such levels, from level 0 to level 6. Each level corresponds to one “click” on the volume rocker of a smartphone or tablet. Accordingly, level 0 is the quietest level, and level 6 is the loudest signal level. Each level can be assigned its own values, which are located in the Value is 0~255 cell, and should not go beyond the range from 0 to 255 (the lower the value, the lower the sound). To do this, you need to erase the old value in the cell, then enter a new one (desired) and press the “Set” button (the one next to the cell) to assign (Fig. 6). When using the maximum values, be careful as the speakers may produce uncharacteristic unpleasant sounds in the form of rattling and other unpleasant effects.

Figure 5 Figure 6

Warning! Before making changes, rewrite all factory values ​​(in case something goes wrong).

You should know this!

Editing modes in the engineering menu

Example 1. How to increase the volume of an incoming call?

To do this, you need to go to the engineering menu, select the “Audio” section, go to the “LoudSpeaker Mode” and in the volume settings select “Ring” - the volume settings for the incoming call. Then sequentially change (increase) the values ​​of all signal levels (level 0 – level 6). Also, for greater effect, you can increase the value of the Max Vol section. 0~160, if it is not the maximum (I set it to 155, with a higher value the speaker starts to “wheeze”).

Example 2. How to increase the volume when talking on the phone? (Increasing the volume level of the small speaker that we put to the ear).

Again, we go to the engineering menu that we already know, press the “Audio” section, go to the special “Normal Mode” mode, select Sph in it - this parameter is responsible for changing the value of all signal levels in the range from level 0 to level 6. Set the desired one for us level. In the Max Vol. 0~160, can also be changed to a higher volume power value.

Example 3. Increasing the volume and sensitivity of the smartphone's conversational microphone

To adjust and set the required volume level and sensitivity of the spoken microphone, you need to go to “Engineering Menu”> “Audio”> “Normal Mode”> select Mic - microphone sensitivity settings, and for all levels (level 0 - level 6) assign one and the same value, for example 240. Now the interlocutor should hear you better.

Example 4. How can I increase the audio recording volume during video recording?

Let’s say there is a need to increase the volume level of sound recording when shooting video, then in the engineering menu for our loudspeaker (LoudSpeaker Mode), change the microphone sensitivity settings (mic), increase all values ​​at all levels (level 0 – level 6), for example, set to 240 at every level. I remind you to press the (set) button - reboot your favorite gadget and rejoice.

By the way, do not forget to press the “Set” button after each edit of a certain parameter. This action should capture and accept your command. Otherwise, the user-specified parameters are not activated. In addition, a certain number of mobile devices require a reboot for the changes to take effect (turn off and on the device).

Good luck in your experiments, if something is not clear, write in the comments. We are waiting for your answers.

Code table for entering the engineering menu

Note: the table is constantly updated

Many users of Android smartphones and tablets are not even aware of the existence of so-called engineering or service codes. Service codes on smartphones and regular phones appeared much earlier than the first version of the Android OS was released. They are intended mainly for service center engineers and advanced users, so we immediately want to warn readers: if you don’t know what this code is for, then you shouldn’t enter it, and if you still decide to enter the code, then do it at your own peril and risk. It is worth thinking before entering any code for Android, because... this may lead to partial or complete loss of data and damage the device itself. If you decide to use codes, let's look at each engineering code in more detail:

*#06# - Find out IMEI;

*#*#4636#*#* - Information and settings;

*#*#8351#*#* - Voice Dialer Logging Enabled;

*#*#4636#*#* - This code can be used to get interesting information about your phone and battery. It shows the following 4 menus on the screen:
— Phone information;
— Information about batteries;
— Battery statistics;
— Usage statistics.

*#*#7780#*#* - This code resets the following settings to factory settings:
— your Google account settings stored on your smartphone;
— data and settings of the system and applications;
- downloaded applications.
The code does NOT remove:
— current system applications and applications supplied with the smartphone;
— data on the SD card (photos, videos, etc.).
PS: Before resetting the settings, the smartphone will ask for confirmation, so until the very last moment you will have a chance to change your mind.

*2767*3855# - Think before entering this code. This code is used for factory formatting, that is, it triggers the deletion of all files and settings including those stored in the internal memory. It also reinstalls the smartphone’s firmware.
PS: After entering the code, there is only one way back - quickly remove the battery and start data recovery via PC.

*#*#34971539#*#* - This code is used to obtain information about the phone's camera. It shows the following four parameters:
— Updating the camera firmware into the image (do not try to repeat this option);
— Updating the camera firmware on the SD card;
— Get the camera firmware version;
— See how many times the firmware has been updated.
WARNING: Never use the first option, otherwise your phone camera will stop working and you will have to take your phone to a service center to reinstall the camera firmware.

*#*#7594#*#* - This code can be used to change the mode of the End/On/Off button. By default, when you long press the button, a screen will be displayed asking you to select any option: “Switch to silent mode,” “Airplane mode,” or “Turn off smartphone.”
You can change the suggested options using this code. For example, you can make the phone turn off immediately, without selecting the desired option from the menu.

*#*#273283*255*663 282*#*#* - The code opens the file copy screen where you can make backup copies of your data (photos, audio, etc.)

*#*#197328640#*#* - This code can be used to enter maintenance mode. You can run various tests and change settings in service mode for WLAN, GPS and Bluetooth;

*#*#232339#*#* or *#*#526#*#* or *#*#528#*#* - WLAN (use the Menu button to run various tests);
*#*#232338#*#* - shows WiFi MAC address;
*#*#1472365#*#* - GPS test;
*#*#1575#*#* - Another GPS test;
*#*#232331#*#* - Bluetooth test;
*#*#232337#*# - Shows the Bluetooth device address;

Codes for running various factory tests:
*#*#0283#*#* - Batch Loopback;
*#*#0*#*#* - LCD test;
*#*#0673#*#* or *#*#0289#*#* - Melody test;
*#*#0842#*#* - Device test (vibration test and backlight test);
*#*#2663#*#* - Touch screen version;
*#*#2664#*#* - Touch screen, test;
*#*#0588#*#* - Motion sensor;
*#*#3264#*#* - RAM version.

These are the basic codes for Android that an advanced smartphone user may need. Let us repeat once again: do not enter codes if you are not sure of their purpose! But to solve some problems in the operation of the Android device, these codes are extremely useful.

Articles and Lifehacks

Just a few years ago, devices with touch screens became incredibly popular. However, many still do not know how to get to the service menu, for example, on Sony Xperia Z or any other smartphone.

The beginning of the “boom” of touch screen devices occurred with the advent of the well-known Prada model from LG in 2007, and very soon this trend was picked up by other manufacturers. The model itself was interesting due to its number of characteristics and stylish design. For example, the video shooting speed was 30 frames per second, and for that year it was very decent. However, the main feature of the device was still the touch screen, which could be controlled using your fingers rather than a stylus. Of course, even before 2007, unprecedented communicators based on Windows Phone were released, but they still remained devices of a completely different class than Prada.

What is the Xperia Z service menu from Sony and how to get there

Unfortunately, not every owner of a mobile device knows what the service or engineering menu is and what it is needed for. Please note that only experienced users should enter it, otherwise you can cause irreparable damage to your device.

The service menu contains information about the smartphone and also allows you to configure certain parameters. In addition, it collects data about the use of the device (information about GPRS, battery, network, etc.). It should be used only if you have the appropriate skills and with extreme care, since any changes made will affect the operation of the device.

So, how to get to the service menu on Sony Xperia Z? To do this, just dial the combination *#*#7378423#*#*. Now you can start using the menu.

Other specs and features of Sony's Xperia Z beyond the service menu

The device was released in January 2013. It runs on Android JB and has dimensions of 139 x 71 x 7.9 millimeters. The smartphone weighs 146 grams. Its body is made of glass. The built-in 4-core processor has a Qualcomm MDM9215M chipset, which has already established itself as a high-quality chipset. Although some believe that the devices on it have , but this is not entirely true.

The smartphone has a capacitive Full HD display with a resolution of 1920 by 1080 pixels and a diagonal of 5 inches. It is made using TFT technology. The screen is protected from moisture and dust. The glass itself is resistant to cracks and scratches. The Xperia Z has 2 gigabytes of RAM and 16 gigabytes of built-in flash storage. There is also support for micro-SD memory cards, which will increase its capacity up to 64 gigabytes.

The device has a built-in 13.1 megapixel main camera and a 2.2 megapixel front camera (with auto focus and flash function). There is support for 1080p video when shooting at 30 frames per second. The smartphone runs on a powerful and non-removable lithium-ion battery with a capacity of 2330 mAh.
