How to open and configure the engineering menu on Android - instructions and secret codes. Secret codes for HTC Engineering menu htc one s

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.

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.

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.

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.

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.

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.

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.

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 pair of 900/1800 MHz, 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.

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.

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.

*#*#4636#*#* hts one engineering menu

Buying a phone is an exciting process, especially if your choice falls on a top-end device. Of course, any buyer will check that the smartphone is turned on, try to find scratches on the screen or metal case, someone may evaluate the operation of the volume rocker or the presence of “dead pixels”. However, the possibilities of “diagnosis” are much wider - HTC One, like any other Android smartphone from the company, has a built-in testing mode.

Vyacheslav Karaiman, a staff trainer at HTC Russia, well known to our regular readers, published a new video on his YouTube blog about an entertaining and useful testing function in HTC Android smartphones. To start it, just log into the “phone” and enter the code *#*#3424#*#* , which can also be read as *#*#DIAG#*#*. After which a warning appears about the need to adhere to a direct sequence during execution, and the user opens the testing application, on the first screen of which there are 15 items and four buttons.

Each item represents one test, but if you want to do everything at once, just click the Select All button. The test chain is started by the Run button, after which the user can only follow the instructions on the screen, which are also provided with explanatory pictures. This way you can evaluate whether Wi-Fi, proximity and light sensors, speakers and much more work in your smartphone.

But that's not all. By pressing the rightmost More key, the user will be taken to an additional screen where 10 more items are presented. This time you can’t check all the boxes at once - some tests are quite lengthy (for example, checking the battery).

Of course, the testing menu is useful not only when purchasing - inquisitive owners can run a test after some time of use to check the performance of certain functions.

What are service codes for?

As for smartphones from other manufacturers, there are service codes for smartphones manufactured by HTC. They allow you to view information about your smartphone, test some of its functions, and change settings. Basically, these service codes, or secret codes as they are called, are necessary for engineers and technicians who repair phones, but they are also useful for ordinary users. But you should enter with extreme caution, since entering the service code incorrectly can damage your expensive gadget.

Service codes

• When you enter the code *#*#4636#*#*, full information about it, as well as statistics on its use, will be displayed on the communicator screen. If desired, you can view the battery status.
• By entering the code *#*#7780#*#* it becomes possible to reset all your settings and set them to factory settings. When installing factory settings, all system settings will be deleted, as well as application settings that are installed on the device. Google account settings and applications downloaded to the device will also be deleted. Resetting to factory settings will not delete only user files stored on the flash card.
• When you enter the code *2767*3855#, the communicator firmware will be reinstalled.
• Entering the code *#*#34971539#*#* will allow you to update the communicator camera firmware from a memory card, as well as see the number of firmware updates. When you turn off the HTC communicator, a menu is displayed on the screen where you can select operating modes of the communicator.

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):

figure 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 negotiations 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). Be careful when using the maximum values, 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.
