Service menu android 4.4 2. Engineering menu on the add-on Android: description

Not a lot of people know about the basis of the engineering menu for the installation of attachments based on the Android OS. The stench can significantly expand the functionality and change a lot of parameters, such as the volume of the sound, making the camera thinner. To go to engineering menu Android needs to enter a special combination of characters in the row for dialing telephone number. When kozhen kozhen vyrobnik maє svіy service code, which consists of digits and symbols "*" and "#". Let's take a look at the main nutrition, connected with the engineering menu, fix the phone: how to get away, how to create that opportunity.

The retailers reverberate and calibrate the skin of their attachments, so that the coristuvachevs in the most vipadkivs do not have to change the way they have been adjusted by themselves. But in certain situations, you may need a little adjustment of a few parameters, for example, the sensitivity of a built-in microphone, or an increase in the loudness of a polyphonic speaker. Specially for such situations, it is assigned to engineering android menu, Access to which can be taken only by entering a single combination of characters. It is significant that changing these parameters is recommended only in a few cases, but it may not be safe for your phone. Therefore, it is recommended to enter the engineering menu on Android only for those who are familiar with it.

How to get to the menu?

The majority of the options for entering the engineering menu have a special combination of numbers and symbols.. You need to enter x in the row to dial a phone number. If the processor of your phone is not MTK, then it is possible to find the brand name of the maker of the code for the engineering menu in Android:

• Samsung. For phones of this brand, there are two options: *#*#8255#*#* or *#*#4636#*#*.
• NTS. Depending on the OS version and model, combinations can be changed: *#*#3424#*#*, *#*#4636#*#* and *#*#8255#*#* .
• Sony. Dial: *#*#7378423#*#*.
• Huawei. Combinations are available depending on the model: *#*#2846579#*#* or *#*#2846579159#*#*.
• Lg. Having typed the combination 2945#*# on most smartphones of the brand, you will go through the menu in the first engineering menu and you can read the instruction manual.

For more Chinese smartphones such as Lenovo, Acer, Prestigio etc. You can open the engineering menu for the help code *#*#3646633#*#*. As soon as the required combination is entered in the row for the phone number, it will appear and the service mode will be changed. If you don't see anything, you need to start it by pressing the wiki button. It is recommended to memorize or write down the values ​​of the external parameters, so that you can remember. So before that, go to the engineering menu, see everything from the dispatcher running programs and active processes.

Alternative way to enter the engineering menu

Possibilities of the engineering menu

Before coristuvach, having removed access to the service settings mode in Android, there are great opportunities to expand the functionality of your device. Through the engineering menu become available:

1. Appointment equal to shkidlivy viprominyuvannya.
2. Testing available types without a dart such as Bluetooth, Wi-Fi, etc.
3. Verification of the GPS signal on Android is the same as the exact alignment.
4. Audio tuning. Installed equal to the sound in the speakers, headphones and microphones.
5. Camera settings.
6. Testing of the central processor, video recording, flash and operational memory.
7. Detailed description of the battery.
8. Testing mirco SD cards.
9. Revising micro USB port.
10. Temperature sensor. Shows the heating of the battery and the CPU.

Zalezhno in vikoristovuvannogo pristroyu, hovering over the list of possibilities when entering the engineering menu may vary. Obviously, the more sensors and modules a smartphone has, the more wines can be installed.

Let's take a look at how to change the density parameters of the butt of a smartphone with an MTK processor. Before that, as I will need the service, it is necessary to enter a combination of characters to enter engineering mode. You can see a long list of completed, in the middle of which you need to select the Audio item and click on the new one. When the menu appears with the number of modes: if nothing is connected to the phone, the headset is connected, the guchnomovets is switched on, etc. More than 5 points are available for skin regulation.

To change the parameters, it is necessary to delete the old value in the middle and write a new one, and then press the “set” button. The value that is assigned is not guilty to go beyond the range specified in the bows. It is also not recommended to beat the maximum available value, the shards will lead to a distortion of the sound.

Android code services

Engineering menu shows access to hand lashing"Zalіznoї" part of the smartphone. To enter, you need to enter a special code, or install the program, and also use a number of features, to get respect for it. If you couldn’t get to the engineering menu the first time, you didn’t care about the specialty of the building. Varto immediately clarify that if you put it into the robot, I can bring it to the point of incompatibility and waste the guarantee.

Attachment of system capability

At the remaining stages of installing a smartphone, retailers test the system for the presence of pardons and check the work of all sensors in the annex. Especially for this, Android has a special subprogram - an engineering menu, which gives access to prihohovanim nalashtuvannyam The Android OS allows you to reconfigure them on your own. In addition, the menu contains information about attachments. New list The possibilities of the menu are less for the retailers of the platform, so make your changes carefully.

With secret stitches of retailers

To enter the engineering menu, dial the code *#*#3646633#*#*. On some models, press the bell key. Warto call on the features of telephones: for different brands, use different combinations of numbers. The Android version does not affect the functionality of the engineering menu.

Enter a special code to enter the engineering menu

If you don’t have any problems, you can go to the add-on menu for fine-tuning your smartphone.

We enter to the menu update

Depending on the system version and processor model, the engineering menu may be incorrect or different. In the photo, I have added a menu with the elements of testing the sensors of a smartphone, setting up a USB connection, and testing the internal and external memory.

Like the first time I didn’t see

Not on all outbuildings, you can go to the engineering menu. Let's look at the broader problems of those paths of their adoption.

Android is a flexible operating system based on Unix. As if you didn’t know about it, you didn’t care about all the nuances of the functioning of those other subprograms.

List of special codes

One of the most common reasons for blocking the entrance to the engineering menu is an incorrect special code. The combination of numbers can be found not only depending on the model, but also on the type of processor. For example, most outbuildings based on the MTK chip are provided with an engineering menu. Just talking about Qualcomm, not all smartphones based on this platform have a built-in engineering menu. The list of combinations is shown at the table. If you don't need it, try another combination.

Table: code options for different Android models

Do-it-yourself engineering menu

If you want a special code, don’t pidish, don’t get confused. Merezha has a lot of programs with the functionality of the engineering menu. Varto respect that the postscript MTK in the names is promotional to talk about the confusion with MediaTek processors.

The first option is Mobileuncle MTK Tools. In this program, the crime of the necessary set is fixed, є kіlka additional functions: Firmware update, recovery update, GPS receiver downgrade mode and more.

Mobileuncle MTK Tools

Another program is MTK Engineering Mode. The program repeats the regular engineering menu.

MTK Engineering Mode repeats the default engineering menu

For those who do not have an engineering menu, there is one more option: installing third-party firmware. The selections of third-party retailers often have a wide range of customizations “for yourself”.

Why start

When you first enter the menu, you can get lost in the net of parameters.

Improvement of the engineering menu

Nalashtuvannya reveals great opportunities for koristuvachs.

Fallow in the hardware platform, the activities may be inaccessible or daily.

You can set parameters for which branch mobile call.

1. Auto Answer. It is available to switch-off the automatic call to the incoming call.
2. band mode. Allows you to manually select Frequency range to the robotic GSM module. Please select all technologies and frequencies for them, which are supported by your smartphone model. For bazhannym you can uncheck the ranges, if not ticked by your call operator. It is essential to save the battery charge. To save the setup, press the set button.
3. CFU Setting (Call forwarding Settings). The option enables or disables smart forwarding. Vaughn can be supported by the operator.
4. AT Command Tool. Utility for retailers that supports AT commands. This menu item will be selected for programmers and retailers. For the help of this menu, you can change the number of drinks without intermediary to the system without visual overhead.
5. modem test. Configuring the summation of the "access point" option different types attachments that are connected.
6. network selection. Here you can select the standard mobile connection (GSM, WCDMA, LTE). For additional energy saving, it is important that you do not vicorate.
7. NetworkInfo. We select one or more options for displaying information about the parameter setting style tie. After choosing, open the additional menu (three dots right-handed upper codend) and press Check Information. This option is useful for checking the quality of services of a mobile operator.
8. GPRS. Setting up a connection to the mobile Internet, choosing an active SIM-card (as well as a kіlka).
9. HSPA info. Information about the 3G measure at different supports by your mobile operator.

Adjusting the loudness of the speakers

At the splitter, you can set up a deep ribbing of loudness, loudness of the earphones and a loud sound.

Before changing the density settings, the next steps are set respectfully. All parameters are individual for specific model outbuildings. Wrong configuration you can bring to the point of destruction the ostentatiousness.

Є low overhead parameters:

1. MaxVol is a fiery rhіven of highness. The range of values ​​is 0 to 160. The higher the number, the higher the number.
2. Sph - fullness at telephone call.
3. Mic - sensitivity of the microphone.
4. Ring - loudness of the speaker at the input ring.
5. Media - rіven stіnіstі nіd аn hour I'll rewatch fіlmіv, listen to music and in games.

Even more often koristuvachі dissatisfied with the volume of the dynamics of the hour of roaming. To improve the sensitivity, go to the Normal Mode menu and change the Sph parameter to 150. to the entrance week, you need to increase the value of the Ring parameter. Radially do not set a value higher than 200, otherwise you can bring the dynamics out of tune. To make you feel a little better, change the Mic parameter from 100 to 172. To increase the sensitivity of the speaker.

ROOT is a panacea for a smartphone

On smartphones without root rights functionality of the engineering menu of the apartment: the items are not shown, change what to bring in is not saved. For whatever vtruchannya, a robot needs a smartphone open access at the system. Don't forget that root access can harm your device, the device warranty will be voided. Recommended backup copy important information to the memory card and to sync with a google account and to ensure that data is not wasted. To unlock full access to the system, you can use one of the basic methods.

Installing the program directly on the device (KingRoot)

The access of the supercorristor can be accessed from a smartphone, vicorist special programs. Let's look at the sequence of operations with the butt of the KingRoot program:

Then you can safely change the parameters in the engineering menu, all changes will be saved. In case of a negative result, we pass to such a method.

Retrieve the rights of a supercorristuvacha through a PC (Kingo Root)

The purpose of this method is to breathe in the trochs great kіlkistyu preparatory visits:

Engineering menus are designed for configuration and I will build and test the robotic stuffing. The program of the system is sewn in, as an indispensable tool, both for the newcomers to the world, and for the newcomers to the world mobile outbuildings. However, the next thing to say is that manipulations with the engineering menu can bring the gadget to a non-working state.

We should know about the richness of customizing Android devices - a leather smartphone or a tablet can be customized for yourself, activating or enabling these other functions, adjusting these and other parameters. But few people suspect about the basis of such a thing, like the Android menu engineering. It's attached to the eyes, shards simple koristuvachevi there is nothing special to work here. But if you want to get it right, if you want to take it from a finely tuned add-on to that operating system, then you will have a good menu.

Let's figure out why you need an engineering menu on a smartphone? The reasoning is simple - I’ll build it for a thin fit. For example, increase in density on Android is only possible through the engineering menu. Here it is necessary to see the point of adjusting the audio and playing around with the presented parameters. Here you can manually adjust the loudness of the sound in different modes and on different gradations of loudness. Let's look at the example:

• You see what's on maximum density the speaker of your smartphone begins to wheeze;
• We go into the engineering menu for additional help and other commands;
• It is passable in the adjustment of the audio and the minimum volume in the given mode and in the given gradation;
• Apparently, from the engineering menu, the results are checked - the thickness may change.

It is possible to take a lesser degree of regulation through standard menu patching? Obviously, there is nothing similar here and close.

Here you can adjust the sound of the headphones, adjust the sensitivity of the microphone, and adjust the sound with other sounds. Before that, how to lie in the nalashtuvannya, it is necessary to know reporting instructions, in order to help vikonati regulation as correctly as possible, without risk, to disturb the dynamics with a microphone, or to allow a smartphone / tablet to voice.

What other functions are in the engineering menu? Rechecking of intermediary modules, adjusting the range of the receiver, adjusting the autowidth, test the modem, adjusting the connection with other devices, adjusting the receiver, testing the camera, sensor, screen, battery and other modules. In addition, the menu has been added to the menu– here you can reverse the operation of the GPS-chip, enable/disable A-GPS, and reverse the adjustment. You can also adjust the fonts, play around with the USB settings and vikonaty іnshі dії.

Respect that the menu service on Android is recognized for professionals, as they acknowledge their own children. If you got stuck around here with a crow's eye, try not to cheat on your parameters and do not rearrange the bells and whistles.

Entering the engineering menu on Android is usually done with the help of special commands similar to the original USSD commands. Notice to those who do not need to press the call button in the end - after typing the command, it will automatically switch over to the given menu. Universal code of the engineering menu on Android - ce code * # * # 3646633 # * # *. Vіn prаtsyuє on rich phones and allow mittєvo enter to service settings.

Deyakі smartphones and tablets do not respond to the command described above. So you can try the following options:

• * # * # 4636#* # *;
• * # 15963#*;
• * # 8255#*;
• * # * # 7378423 # * # * (for Sony smartphones);
• * # * # 3424 # * # * (code for HTC smartphones);
• * # * # 2846579 # * # * (code for Huawei smartphones).

Entering the engineering menu on Android will be concatenated the next time the command is entered. Depending on the version of the operating system, there is no code for Android 2.2, Android 4.4 and other versions of Android OS. If the code does not match, then search for other combinations.

Deyakі command prizvodlyanya not in the menu service, but in the test menu - it allows you to change the screen, sound, wireless modules, microphone and a lot of other things. The menu for testing can be English and Russified.

Deyakі virobniki pozbavlyayut smartphones and tablets access to the engineering menu, replacing it with numerical commands for testing modules or adjusting the silence of other parameters. For example, so rob the Samsung company - a lot of new models have been added to a single service menu. Information about available service commands can be found on specialized resources and on the websites of service centers.

To access the engineering menu, you can twist special programs . A typical stock is the Mobileuncle MTK Tools program. It is allowed to allow otrimati different access to the settings and settings of the operating system. The program is effectively handy, but it has a shortcoming - it works exclusively on outbuildings with MTK processors.

If your smartphone/tablet works on another platform, you can try searching for alternative programs to access the Android engineering menu.

Nalashtuvannya Android through the engineering menu is connected with singing risks. For example, for newcomers, it is possible to switch on the same functionality. Determining from the recognition of quiet and other points, it is necessary to be aware of the relevant instructions. In another day, the weather is possible. You're afraid of being naughty and evil, you're afraid backup copy I’ll build my own - at times fatal pardon you can vikonati hard reset and change your smartphone or tablet.

Never enter commands that you don't recognize. On the right, in the fact that some of them are created for the operational change of critical parameters of the system, or for vikonannya zagalnoy skidannya. Moreover, the deacons command to win the wildest throwing off without confirmation, mittevo erasing the whole place.

Corylists of mobile accessories often confuse the engineer of the Android menu with the menu of retailers, although most of the coristuvachivs don’t know anything and don’t think about it.

Age ti, who does not marry new products and does not buy when a new skin appears android versions, also think about expanding the capabilities of your device

In order to solve the problem, you can go in a number of ways:

Zmist:

Yak to go

The most expanded version of the wiki on Android devices is the introduction of a combination "*#*#3646633#*#*".

Respect! There are a couple of nuances here:

• firstly, after the combination is entered, it is not necessary to press the button, after a couple of seconds after the introduction of the remaining symbol, the required interface will appear on the smartphone screen;
• zastosuєmo method to greater, but not to all devices and firmware versions, especially to Chinese outbuildings;
• old look and functions, which are hoped, may be changed on different devices (number of categories, names, details of versions, etc.).

On other models try to enter *#*#4636#*#* otherwise *#15963#* . Combinations for mobile attachments in the most popular types are listed in the tables below.

Just don't give a damn

It is even rarer, but perhaps more likely, that one of the suggested combinations did not lead to the week of the necessary victory. At this time, the Mobileuncle MTK Tools program is vanquished (seen from ).

It works similarly to the methods described above, with the same authority that the commands for entering the codes are available on the mobile phone operating system automatically, having selected the version of that gadget model after the prompt of the Engineer Mode command.

It is strongly recommended to the program users, it’s not for nothing that they saw the add-ons from the store - a lot of dozens of coristuvachiv “driven” the firmware of their attachments through a nevmila and nedbale cause with the software. Let's open the option window and the program allows:

Extended interface warehouse

Engineer Mode for the koristuvach is presented in the rich window, and on the skin of the tabs of the selected sing functions.

Telephony

On the first tab, the placement of functions for the viconann infamous lashing by phone: , testing of measures and otrimannya of information about vicory mesh technologies, changing the GPRS parameters, configuring the camera and the mass of the unknown for the newcomer subpoint.

Connectivity

Reply for changing parameters and displaying information about ports for communication:

About the skin module, you can ask for secondary information, protest against the robot, change the configuration and burn out the logs.

hardware testing

I have named a section on those tools that are present here for work out of doors: conducting a test, removing any information about hardware components, changing the modes of their function.

On Android, there are more than ten modes for creating audio for different minds ( , call, ).

As far as the camera is concerned, there is a wide range of parameters available, which include changing the preview of the videos and the frame rate of the video for closing and anonymous points.

To check the stability, you can run a stress test of the processor through it.

Change the voltage and operating frequency with a method of overclocking or save batteries next to the edge carefully and ascertain possible risks.

For the processor, the option of putting yoga into sleep mode is available for singing minds, as well as the display being turned off.

Also, in Engineer Mode, there are selected anonymous items for removing data and adjusting the robotic processor, touch display, and sensors.

Establish the function of the teeth and change the operating mode.

location

For those who like to bask in the possibilities of GPS, as they don’t need to fix it, there are plenty of points available in this deposit.

Log & Debugging

Logs and files with information about the modes for the battery, memory and a large number of settings for the inclusion of non-essential information from the logs, change the directory of their savings.

Other

Rest tab I took in myself everything that I did not know the place in the front. Price (size change, size change) and number of inaccessible without root-privilege functions.
