How to enter the highscreen engineering menu. How to enter the phone's engineering menu? Increasing phone volume through the engineering menu

Purchasing a new smartphone or tablet is a real holiday for many. Each owner expects that the gadget will delight you for many years with its reliable operation and the absence of any problems. Moreover, regardless of who the assembler is and what control system is installed.

However, as often happens, modern mobile devices can hardly be called ideal, since some time after the start of use, issues are identified that the owner wants to correct, in one way or another improving the software part of his mobile assistant to the ideal. Of course, in my understanding. One of the available tools is the Android engineering menu.

Secret settings that everyone knows about

At the final stage of configuring the software component of the gadget running the Google system, developers use the so-called Android engineering menu. a special program that allows you to make adjustments to the operation of the device, perform technological tests, and view information from sensors. Since thoughtless use of this tool can lead to unpredictable results, access to it is most often hidden from users. However, in fact, the secret is already known to everyone - to learn how to call up the mentioned menu, you only need to spend a few minutes searching for recommendations.

A few important points

However, not all mobile devices can log into the Android engineering menu. In order to take advantage of its capabilities, you need to make sure that the gadget meets certain requirements.

Firstly, the central processor must be manufactured by MediaTek (or MTK). On inexpensive Spreadtrum models, for example, SC-6825, popular Snapdragon from Qualcomm, various Tegra NVidia and Intel, trying to launch the Android engineering menu is useless. It is not there. It will not be possible to achieve functionality, even if you carefully install the appropriate application.

Secondly, various modified operating systems, for example, CyanogenMod, popular in some circles, do not allow running the configuration program, since they were originally developed for devices with a Qualcomm processor that do not support the Android engineering menu. In addition, it is highly desirable that the operating system be original or created on a basic basis.

Thirdly, the application itself (file) must be present among the programs, even if hidden from the standard Explorer. Thus, some mobile device manufacturers, after completing the software settings, simply delete the “Android” engineering menu. Descriptions and recommendations for use in this case are useless, which is obvious.

Secret combination

There are several ways to get into the engineering menu settings on Android. It is impossible to say which one is better, since a direct comparison is incorrect. Therefore, we will consider them one by one.

One of the most “ancient” options, which was used in the first models of smartphones and tablets, is that the user in the dialer program (the so-called dialer) dials not the subscriber’s number, but a special code of the Android engineering menu, similar to checking funds in the account. If the combination is recognized and accepted, the configuration application is launched. Some mobile device companies use their own modified code, so the standard set does not always work. Otherwise, to call the menu, you should type the following character order without spaces - * # * # 36 46 633 # * # *. It's that simple.

Traditional access method

Using a secret combination is not always convenient, if only because the order of the symbols is easy to forget. Also, in the case of a changed set, it is easier to use the program rather than looking for the correct order of characters. One of the most famous applications is the so-called “Mobile Uncle”, or MobileUncle Tools. It is free, so there are usually no problems with finding and installing it. At the time of writing, the current version is the official 2.9.9 or build 3.1.4, which has additional support for some new processors.

In order for the program to work, the user must first obtain root rights on his gadget. There are a lot of applications for this, for example, KingRoot, SuperSu, etc. In this article we will not talk about the nuances of working with a rooted device, since this is a separate voluminous topic. After launching the application, you should select the third item called Engineer Mode (both in Russian and English versions), and in the window that opens - “Work with MTK”. When prompted to provide root access, you must answer in the affirmative.

How to restore access to the engineer mode

If the manufacturer of the mobile gadget took care of the security of the operating system by prudently removing the configuration program, then it can be reinstalled. To do this, you need to find an installer on the Internet that restores EngineerMode.apk and install it.

We do not indicate the exact name due to the abundance of analogue clones. For example, one of them is called “Engineering Mode”. You can also simply copy the missing file to the system folder located on the system\app path. After this, you can use any method for access: either dialing a number or directly calling from the program interface. Please note that these operations require

Features of the miracle program

Through the engineering menu, despite the ambiguous attitude of gadget owners to this, it makes it possible to solve several important problems. In particular, adjust the sensitivity of the microphone, cure the “childhood disease” manifested in insufficient volume of the system speaker, reduce battery power consumption by disabling scanning of “extra” ranges, and reduce the time it takes the global positioning system receiver to search for satellites. Let's look at the above functions in more detail, since they are the ones that are most in demand.

Ringer volume

Raising the ringer volume is very easy. To do this, select the “Audio” section by swiping to the right. A list of modes will appear. LoudSpeaker Mode, Ring subsection, is responsible for the system speaker. The parameter in the first window should not be changed, but in the second you can enter a higher value. The developers may have initially set the indicator to 130, which is quite quiet, but 156 is already close to the limit. The maximum is 160. After editing, you need to press the Set button, located here, and reboot the device, correctly exiting the program.

Mobile operator frequencies

To optimize the power consumption of a mobile communication device, you can disable scanning of “extra” frequencies. In our country, when working in regular 2G/3G networks, the standard frequencies are 900 and 1800 MHz. The other pair, 850 and 1900 MHz, is an American standard. To enable or disable it, you need to select the Band Mode item, go to the settings for SIM-1 and SIM-2 one by one and uncheck/check the desired boxes. Confirmation is by pressing the Set button.

How to improve GPS? To improve performance, you need to turn on Wi-Fi, select Location in the Android engineering menu, go to Location Based Service and open EPO. Here you need to make sure that the Enabled and Download checkboxes are checked (if present). After this, you should return to YGPS and in the information section, alternately click “Full”, “Cold”, “Restart”. Next, you need to select the “Satellites” item and wait until the answer is recorded (green dots on the map). Everything takes from 2 to 5 minutes. After this, all that remains is to exit the menu, close the program and restart the gadget.

Summing up

The engineering menu of devices operating under control opens up opportunities for the owner of the gadget, the use of which allows you to configure the device in an optimal way. This is often the only way to delay the purchase of a new mobile assistant. This menu is contraindicated only for those who are already completely satisfied with the operation of their tablet, navigator or smartphone.

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 mine 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

A beginner who has bought a smartphone or tablet based on the Android operating system, after a while, feels the need to reconfigure something in it or adjust it more precisely. Entering the Android engineering menu is simple: you just need to know the special commands.

The hidden engineering menu in Android devices allows you to manage system settings of your smartphone or tablet that are not available in the standard menu. For example, they allow you to increase the speaker volume during calls, forcefully select the frequency range of the network being used, enable a photo or video format that is not in the main camera settings, etc.

Parameters configured in the engineering menu

Using the engineering menu you can access functions such as:

• speaker or headphone volume;
• improved speech recognition;
• microphone sensitivity;
• voice quality when making calls;
• forced cellular network selection mode: “GSM only”, “WCDMA only”, “LTE only” (some network modes may not be available in the standard settings);
• binding to one base station, frequency or channel number;
• choice of technology and cellular data speed;
• testing and overclocking the processor;
• enable/disable sleep mode;
• testing Wi-Fi and Bluetooth radio modules;
• auto-switching 2G/3G/4G in sleep mode;
• camera test drive;
• changing the photo format (default is JPEG or PNG);
• fine-tuning the display brightness and its response to illumination;
• locking/unlocking auto answer settings for incoming calls;
• improved GPS performance;
• full “reset”, including factory formatting of the smartphone;
• testing and setting motion sensors;
• testing color rendering on the display;
• testing and setting up vibration alerts;
• backup of multimedia files;
• determination of the level of harmful radiation (SAR) on a single device;
• FM radio settings and behavior.

Commands for accessing menus

Commands for accessing the engineering menu vary depending on the manufacturer. There are also common commands for all versions of Android that allow you to configure individual device functions.

Main codes for entering the engineering menu

The commands you enter vary for different brands of devices - select the ones that suit you. It is not forbidden to check everything - commands that do not correspond to a specific manufacturer simply will not work.

Table: commands for accessing the engineering menu of various manufacturers

Google Commands for Android OS

Factory Android service codes, which show technical information about the device, are often not associated with the manufacturer. Basically, they are all built into Android by default. The range of “numbering” of commands has been agreed upon by Google - as the creator of the Android operating system - with manufacturers of tablets and smartphones.

Table: Android factory service codes

The most popular service codes of the engineering menu

The most popular codes that allow you to change smartphone settings through the engineering menu do not depend on the phone brand or Android version.

Table: service codes for changing phone settings

When using commands, keep the following in mind:

• By updating the camera firmware through the engineering menu, you can find out about the version of this firmware and the number of its updates - and also save this update to an image in the internal memory and on the SD card. It is not recommended to reflash the camera again - if it fails, you will simply ruin it;
• When you reset your Android system and delete all Google user data, a message asking you to confirm the reset will appear on the screen.

How to enter the engineering menu

To get to the engineering menu, follow these steps.

Video: how to open the engineering menu on Android

What to do if you can’t enter the menu

It happens that none of the commands intended for a particular brand of device are suitable - this is how the manufacturer protects inexperienced users from not fully thought-out actions. Some manufacturers, after software debugging of a smartphone, completely remove the engineering menu, and all of the above commands simply do not work. For example, Samsung does this. Some of the commands you enter can harm both the Android software and the device itself.

Often, instead of general service commands, more specific ones are triggered. If, despite all your attempts to “reach out” to the engineering menu, none of the service codes work, you need special applications.

Install the free Mobileuncle Tools application - it will distinguish between hardware and system settings. You may need to obtain Root access on Android. There are other applications: EngModeMtkShortcut, BetterCut, etc.

How to save settings

In order for the settings made using the Android engineering menu to be saved, you need to exit it correctly. While in any section of the engineering menu, use the on-screen “Back” key either in the menu itself, or press the cancel call button or the “Back” key under the display - it is indicated as a reversal arrow - to go to a higher level of the engineering menu.

It is not recommended, after setting the value of any setting and confirming it with the Set key, turning off or rebooting the smartphone by pressing the power button, removing the battery from the device, etc. Exiting the engineering menu can involve pressing - sometimes holding for a few seconds - the same “Back” key below the display. When you exit the engineering menu, a message will appear on the smartphone screen asking you to save the settings you have made - confirm it. There are tips on some of the sections of the engineering menu:

The reason why the engineering menu still does not save the settings may be “raw” firmware. Find out which Android versions and builds are right for your device. If you have a branded smartphone with a version of Android that has pre-installed programs and components from Beeline, MTS, MegaFon or Tele2, feel free to install a “custom” version, for example, the well-known CyanogenMod assembly. Any earlier - or, conversely, the most recent - version of Android may be suitable.

In some cases, it is impossible to enter the engineering menu without obtaining Root rights. The task is to make an Android smartphone “rooted”. In other words, get “superuser” capabilities on your smartphone, allowing you to take the smartphone under the clearest and most complete control. This is achieved in the following ways, use any of them.

1. Install a custom (modified) version of Android on your smartphone. It already includes the Superuser software component, which provides access not only to the engineering menu, but also to the system folder.
2. Download from the Android Market any of the apps that can hack Android without using a computer. Different programs are suitable here: Universal AndRoot, Unlock Root, z4root, Revolutionary, etc. Not all of them can help - you will have to test everything until it works.
3. You can also try applications for Windows that perform all manipulations with Root access on a smartphone directly from the PC - for example, the VRoot program. You also need a USB-microUSB cable - it is impossible to hack Android on a smartphone via Wi-Fi.

After receiving Root privileges, the smartphone is ready to activate the engineering menu using third-party Android applications.

The more recent the version, the more settings in the engineering menu will be in Russian. In the earliest versions of Android (1.x, 2.x), all service settings were in English. Having learned a little technical English, you can easily remember the purpose of each of the settings and, if necessary, you can change them all in a few minutes.

The availability of the engineering menu - in whole or in part - is decided not by the Android version, but by the make and model of the smartphone. Try different combinations and programs, but don't get too carried away.

If you perform inept actions or forget the entered codes, there is a risk of turning your smartphone into a lifeless device, and only a service center will be able to restore it to you. And since if you “root” the device, you automatically lose the warranty.

The Android engineering menu is one of the most useful tools for an “advanced” user, preventing him from wasting the hardware resource of his device and the resource of cellular and wireless networks. And it doesn’t matter what version of Android you have - 2.2, 4.2.2, 4.4.2 KitKat, 5.1, 6.0 or another - the engineering menu codes are determined only by the manufacturer. By completely subjugating your smartphone or tablet, you will deprive it of the opportunity to “live its own life” not according to your schedule, but according to the scenario of the manufacturer itself, cellular operators and other intermediary companies that are in one way or another involved in the operation of mobile equipment in cellular networks. This is the shortest path to professionalism.

Few people know, but in Android there is a menu of advanced settings, the so-called “Engineering menu”. And if anyone has heard about this, they may not know how to enter this very menu on Android. It is in this article that I want to tell you how you can get into this section.

Engineering Codes for Android: Video

How to get to the Engineering Menu

Entering this menu on Android 4 occurs by entering a special key combination in the dialer, the so-called code; each manufacturer usually has its own combination. So, you need to go into the dialer and dial:

After typing the code, the “Engineering Menu” should open immediately, but if this does not happen, you should try pressing the call button.

What features are available

After logging in, a large number of settings will be available (for advanced users). One of the simplest is changing the volume at each level, that is, you can specify what volume will be at the 1st level, what at the 2nd and so on. This will be useful for phones whose standard volume is too quiet, making the value at the last level higher than usual. I suggest you look at everything using an example.

• Then select the “Engineer Mode” section

• Since we need to change the volume value, select “Audio”

• Next you will need to experiment with the values; as a rule, the numbers can be set from 0 to 160. Where 0 is no sound at all, and 160 is the maximum volume.

Also, you can make many other changes, in theory, almost the entire functional part, for example, adjust the vibration strength of the phone, the reception strength of the radio module, and much more. If you like to experiment, then there is just something to have fun with, just be careful when changing the values, because in the wrong hands, you may not customize the device for yourself, but on the contrary, only make it more inconvenient to use.
This is actually the entire manual on how to get to the advanced settings menu on Android 4. Nothing complicated!

Not every person who has their own mobile phone thoroughly understands the various features of their device and the intricacies of its settings. In particular, many people do not know how to enter the phone’s engineering menu and why they need to do this at all. In fact, the engineering menu often becomes one of the main tools of specialists from various service centers, who eliminate all kinds of firmware errors or any malfunctions in the internal program of the device.

How to login?

Many people have heard about the engineering menu and know that you can enter it, but do not know how. You can enter the engineering menu by dialing *#*#3646633#*#* and pressing the Audio button, or simply by using the specialized MTK Recovery utility.

Audio

There are several categories in this section:

• Set Mode - select a profile.
• Normal Mode - standard profile.
• Headset Mode - mode for using a special headset.
• LoudSpeaker Mode - a mode in which the loudspeaker in the phone is activated.
• Speech Enhancement is a mode in which fully automatic correction of speech signals is carried out.

Before choosing any extreme values, you should make sure in advance that this will not cause you to experience any sound problems later. In the vast majority of cases, it is highly not recommended to do this for the reason that maximum settings can provoke the appearance of a rattling effect and a whole range of other interference, and will also create an extra load on the speakers, which provokes their faster failure.

In addition, never forget that before changing any settings, you must write down those that were set by default, so that if any problems arise, you can quickly return them to their original value.

Normal Mode

After you have figured out how to enter the phone’s engineering menu and what its main paragraphs are, go to Normal Mode. Here you will see a menu in which there are four items, among which the first item is the profile number. Paragraph FIR - 0 - should be left and not touched, and then move on to the next characteristics.

Initially, you should configure the overall volume modulation Tone, for which in the corresponding Value paragraph you will need to set the optimal volume value and press the Set button. Initially you can set it to 1, or try a variety of options from 0 to 100. The higher the value, the quieter the sound, while 0 is the maximum possible volume. But, as mentioned above, it is highly not recommended to set the value to zero, since the speakers will begin to produce a wide variety of side effects, such as sound rattling and much more.

Now we go to the Type Side tone menu, but here initially it is not recommended to touch anything, since it may happen that during the conversation you will only hear yourself, but not the interlocutor. Or try changing the values ​​in different ways at your own risk. The most suitable characteristics are the following:

• Audio - 1.
• Speech - 1.
• FM - 1.
• Microphone - 1.
• Key-tone - 70.

If it seems to you that the music or radio is playing too quietly in the headphones, then you can slightly adjust the profile for the headset, but do not forget to restart the phone after that so that the settings are saved.

How to change the conversation volume?

The conversation volume changes through the engineering menu as follows:

• Let's go to the menu.
• Select Audio.
• We find the Speech enhancement characteristic, which is responsible for how well we hear the subscriber on the other side.
• Click on the Common Parameter button, and then select Normal Mode.
• Now look at the parameter Parameter (0), after which we set Parameter - 6.
• We begin to edit this parameter and change it from the standard 400 to 1, after which we press the Set key.
• Now audibility will become even more than acceptable, and in some cases you even have to lower the volume (Samsung’s engineering menu often gives this effect).

Headphone volume

By setting the following characteristics, you can adjust the volume of headphones or speakers in the direction you need while watching a video, as well as listening to music or the radio:

HeadSet Mode (type):

• Audio = 10.
• Side Tone = 50.

LoudSpeaker Mode (type):

• FM = 10.
• Side Tone = 50.
• Audio = 15.

Normal Mode (type):

• FM = 10.
• Side Tone = 50.
• Audio = 20.

By setting these characteristics, you will get an acceptable volume while listening to any material. In particular, this allows you to create both the Samsung engineering menu of modern models and the menu of most other phones.

Service menu

The service menu also has several main items that may be of interest to users:

1.BatteryLog. The engineering menu of FLY and other modern phones allows you to get extremely accurate information about the condition of the battery, including temperature, voltage and other subtle parameters.

2.TouchScreen. A fairly wide parameter that has the engineering menu of FLY and other manufacturers that produce modern touchscreen phones. There are several submenus in this section:

• HandWriting. A fairly simple option is to draw with your finger on the screen, which allows you to check how well the sensors respond to touching them.
• PointVerification. Allows you to diagnose and, when you press the corresponding button, shows whether there are any errors and, if so, how much they deviate from the desired value.
• LineVerification. Almost the same as the previous point, only here lines are drawn from one point to another.
• ShakingVerification. Shake test.

additional characteristics

In the Type paragraph, you can also change other characteristics that interest you, from the volume of the speaker during negotiations (Speech) to the volume of keystrokes (Key tone). Again, all parameters must be set to a value between 0 and 255, after which the Set button is pressed, which saves the characteristics. The exact same procedure is also established in Headset Mode if you want to fine-tune the volume of your headphones. If you are a fan of a fairly high volume, which the phone cannot initially provide you with, then in this case the optimal values ​​for you will be from 1 to 5, but not 0.

It is immediately worth noting the fact that these are not specific volume values, but only the principle is described. The specific values ​​will directly depend on the characteristics of your speaker and microphone, because, for example, the settings provided by the Explay engineering menu can bring the parameters an order of magnitude higher than the capabilities of your phone, as a result of which it may simply break while trying to meet these parameters. Take this into account and try to choose realistic characteristics that can meet your needs.

How to check?

In most phones, the engineering menu provides a specialized Ring Tone item, which can be used to listen to any standard melodies directly from the engineering menu in order to determine how much we have changed the volume. Of course, it is best to call someone after completing all the settings and check the settings live, but if you are trying to do everything quickly and do not want to spend a lot of time, this function is the most optimal for you.

Increase the volume of conversations

The conversation volume is adjusted through the engineering menu in the service menu described above. You can enter it as follows:

1. Dial *#*#3646633#*#*.
2. Install the specialized program Mobileuncle Tools on your phone. The first menu in this program is the entrance to the engineering menu of phones. Using the program is much more optimal than doing everything manually, since there is no need to enter a large number of numbers. After all, only the values ​​that will be optimal sometimes have to be selected within several hours.

After this, you can dial different numbers and check how well you can hear your interlocutor and yourself.

Explay Features

A separate feature of the Explay engineering menu is the Battary parameter, which is responsible for battery levels. This characteristic determines the battery charge level and tells the phone when to turn off the power while charging. Thus, you can slightly increase the battery life of the phone, but you must understand that this also affects the battery life, so changing these characteristics is not always the optimal solution.

It is also worth noting that the new type of phones have a function where when the battery is low, you cannot call other subscribers. It is in this situation that knowledge of how to enter the phone’s engineering menu to change the battery characteristics may come in handy, which will allow you to use its resource longer on outgoing calls.
