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 receive interesting information about the phone and battery. It shows the following 4 menus on the screen:
— Phone information;

— 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 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 shown 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.

Articles and Lifehacks

Just a few years ago, devices with touch displays have become 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 a 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 main feature the device has become touch screen, which could be controlled using fingers rather than a stylus. Of course, even before 2007, unprecedented communicators were produced on Windows based Phone, however, they still remained devices of a completely different class than Prada.

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

Unfortunately, not every owner mobile device knows what constitutes a service, or engineering menu, and why it is needed. Please note that you only need to enter it experienced users, otherwise you may 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 besides service menu

The device was released in January 2013. It works for Android based 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 proven itself as a chipset High Quality. 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. Xperia Z has 2 gigabytes random access memory and 16 gigabytes of built-in flash array. 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 front-camera 2.2 megapixel (with auto focus and flash function). There is support for 1080p video when shooting at 30 frames per second. The smartphone runs on lithium-ion powerful and non-removable battery capacity 2330 mAh.

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 very loud noise in 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 common understanding I'll tell you a few examples.

Example 1. You are listening to music on your phone, turned it on 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 begun to hear you poorly, this is because 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 telephone dialing numbers: we write 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 smartphones, Alcatel, Philips

*#*#2846579#*#* – Huawei smartphones

Congratulations, you have entered the engineering menu (Fig. 2). Please note that the menu is 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 device and you turn on 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 completion phone call V root directory memory cards, corresponding files are created. Their name and structure are next view: 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 it.

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, your view will become available various settings volume (Type). 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 conversational dynamics(the one we apply to the 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– volume level adjustment 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 maximum (I set it to 155, with 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 we already know, press the “Audio” section, go to special mode“Normal Mode”, in it we select Sph - this parameter is responsible for changing the value of all signal levels in the range from level 0 to level 6. Set the level we need. In the Max Vol. 0~160, also can be changed to more high value volume power.

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 after each edit a certain parameter press the “Set” button. This action should capture and accept your command. Otherwise, user installed the parameters are not activated. In addition, a certain amount 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.

Video: how to work in Engineer Mode

If the code does not work and in a standard way it is not possible to start the service menu, 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 installed firmware Cyanogen Mod. 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: creation, search, deletion. It does not have a direct function for entering the engineering menu. But with its help you can view the list secret commands, valid 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 extra 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 in 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 you will see a list on the screen possible actions, among them - “Get root”. Select this item.
  3. Choose one of the preset root methods.
  4. The program will begin installation.

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

Appearance engineering mode and options for adjusting settings 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 - menu item names may vary depending on various models devices! 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.

Change the values ​​one by one maximum volume 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 same values microphone sensitivity, 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 consume 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(Recovery mode) – analogous to Bios on a computer, allows you to control the device without logging into Android system. Recovery mode features:

  • resetting settings to standard;
  • firmware update;
  • access to root rights;
  • Creation backup copy 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 service code didn’t work, don’t be upset - 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.
