Manufacturers are always tweaking their interfaces, and with EMUI you can easily see changes from a Chinese manufacturer. The user interface offers an experience that is different from the original Android. In this article, we'll look at some of the features worth knowing to get the most out of your smartphone, be it the , or the Honor View 10, to name just a few devices from the ever-growing Huawei/Honor family.

Important: There may be slight differences between Honor and Huawei devices.

How to configure the interface?

One of the advantages of EMUI is, without a doubt, the level of customization. Use your own photo as a background, organize apps in a separate tray, customize physical or virtual keys, rearrange the order of apps on screens to tailor the interface to your tastes and needs in just a few steps.

Change background: Settings - Display - Wallpaper - Set wallpaper - Gallery / Other.

Application tray: Settings - Display - Home screen style - Application tray.

Battery

Unfortunately, there are no miracles here. You won't be able to get your smartphone's battery to last more than two days. However, you can monitor and manage battery consumption using special settings. If your smartphone supports this technology, you can use fast charging to get the energy you need in a short time.

Turn on power saving mode. To limit apps running in the background, turn off automatic email sync and system sounds.

Select power saving mode: for emergency situations, this mode allows you to limit the use of applications, which will significantly limit the user's capabilities.

Understand what's draining your battery: Settings - Battery - Battery usage.

Scheduling an alarm on your smartphone: Settings - Intelligent Help - Enable / Disable schedule. Set the wake-up time and then the alarm time.

Transfer data from your old smartphone: Download Phone Clone on both devices (Huawei, Honor or Apple), select the data you would like to transfer.

Improved sound quality: Settings - Sound - Huawei Histen Sound Effects (connect headphones to your phone, otherwise the item will not appear in the menu).

In almost all applications in this category, you will see the same sound settings. This is because equalizers for Android use the same set of system functions (APIs), open in the OS to third-party developers. As a result, such programs differ only in the interface, the presence of additional features, the amount of advertising and the price.

Therefore, in order to find equalizers worthy of attention, it is best to weed out applications that are inconvenient, buggy, too expensive, and that abuse advertising. Listed below are programs that have undergone such selection.

1. Equalizer FX

Minimalistic equalizer with 12 preset profiles for different musical styles. You can edit them to your liking and save your own profiles. The application can create a surround sound effect, enhance bass and limit the volume of the device.

After installing Equalizer FX, an icon appears on the notification panel with which you can quickly go to the equalizer menu from any open program. In addition, Equalizer FX can turn on and off automatically when you play or pause audio playback.

The free version has no restrictions, but displays advertisements. Ads can be disabled for 99 rubles.

2. Equalizer - Bass Boost

This equalizer is comparable in capabilities and level of convenience to FX. Its arsenal includes 10 presets for various genres, and the user can create his own. The app also supports all the standard effects: bass boost, volume boost and surround sound.

The equalizer icon on the notification panel provides quick access to sound settings. The program can turn on itself when you connect headphones or start the device - depending on the selected settings. But after turning it off, it does not remember the last active profile and changes it to the standard one.

The advantages of Equalizer - Bass Boost include beautiful interchangeable design themes, but most of them are available after making a payment of 99 rubles. You can also create more than one music profile and increase the maximum volume only in the paid version, which is also devoid of advertising.

3. Precise Volume

This app combines equalizer features with additional options for audio control. Like both previous programs, Precise Volume has a set of ready-made profiles for musical styles (seven pieces) and the ability to customize new ones. The application can also increase the maximum volume level, enhance the bass and create a surround sound effect.

Thanks to the Precise Volume icon in the notification panel, you can always quickly open the equalizer menu.

Among the additional features of the program is setting the maximum volume of headphones, which can protect your hearing. Moreover, Precise Volume allows you to customize profiles for all system sounds. So, you can set volume levels for multimedia, calls and other sounds and save them as a sound scheme, for example, for an office or cinema. In the future, it will be enough to activate this circuit to prepare the device for the required operating conditions.

All of the listed features of Precise Volume are available for free. To get even more options to control the device’s sound and remove advertising, you need to pay 140 rubles.

The external speaker of modern phones performs its functions well during a telephone conversation. But given that smartphones are becoming thinner and thinner every time, it is almost impossible to fit a high-quality speaker into such a phone body. Therefore, it is not practical to demand the highest sound quality from a mobile phone.

And if you want to use your smartphone as a music player, then you will only have to listen through headphones.

Since modern life is full of active events, this leads to the fact that it becomes impossible to retire to listen to music in conditions of ideal acoustics. Therefore, you have to listen to your favorite music with headphones on the go, and, as a rule, in the loud noise of an “active” metropolis.

In this regard, HUAWEI (honor) smartphones have very good software that allows you to improve the sound in the headphones, so that their owners are satisfied with the sound and can customize the sound to their tastes.

How to adjust the sound in Huawei (Honor) smartphones?

It is necessary to immediately clarify that everything that will be described below applies to listening to music only through wired headphones. Huawei's proprietary Histen sound processing algorithms implement various audio effects, which can only be accessed when headphones are connected.

In the audio effect settings, there are three types of headphones to choose from:

• Intrachannel;
• Plug-in;
• Invoices.

Therefore, the presented typical sound settings were developed for each type of headphones.

When developing Huawei Histen audio processing algorithms, the entire variety of settings options was reduced to two main sections:

• 3 D-audio;
• Equalizer.

Section 1 - 3 D-audio.

When mode 3 D-audio sound settings are selected to achieve the effect SURROUND SOUND.

In this mode, there are only three surround sound modes for each type of headphone:

• “Close” for classical music;
• “Front” with stereo zoom and for watching video;
• “Surround” to simulate the acoustics of a concert hall.

These effects are recreated using echoes and dips in various areas of the Amplitude-Frequency Characteristics (AFC), achieving an increase in the “imaginary” distance between instruments and expanding the stereo panorama.

Section 2 - Equalizer.

To realize your individual preferences and fine-tune the sound, there is a 10-band mode Equalizer. Here you can make the most precise sound adjustments in order to adjust the sound of different headphones in order to hide their shortcomings and emphasize their advantages.

In the Equalizer settings there are 5 ready-made settings for the type of music:

• Classic;
• Jazz,
• Dance.

Moreover, for each setting there is the possibility of additional bass enhancement.

And for particularly advanced music lovers, there is a mode for individual Equalizer settings.

How to set up audio effects on your phoneHUAWEI (honor)

1. Go to your smartphone Settings by clicking on the icon « » .

2. If wired headphones are not connected to the mobile device, then we will not be able to enter the “Huawei Histen Audio Effects” section. Therefore, we insert the headphone jack into the appropriate socket.

3. Now you need to select the type of headphones you have. To do this, click on the icon "Headphone type".

• Intrachannel;
• Plug-in;
• Invoices.

4. Further settings depend on the type of sound perception preference:

• 3 D-audio— in case of preference for the surround sound effect;
• Equalizer- in case of preference for individual sound settings.

If you select the SURROUND SOUND mode, you need to press the switch " 3 D-audio".

5. When selecting the individual settings mode, click on the “ Equalizer».

Here you can select one of 5 ready-made equalizer settings or go to the individual “Settings” mode of the 10-band Equalizer.

By selecting a ready-made mode (in our case "Pop"), you can further enhance the sound of low frequencies. To do this, move the slider "Bass Boost", set the desired sound of low frequencies.

To customize the equalizer you need to click on the icon "Tune".

Clicking on the icon "three dots" in the upper right corner of the screen, and then to the icon "Save", you will save your individual settings.

Many of us have long fallen in love with smartphones based on the Android operating system. They have always captivated us with their unpretentiousness, good reliability, as well as convenience and ease of use. The same can be said, in particular, about the well-known smartphones, which are also based on this operating system. The company from the Middle Kingdom always keeps up with the times and equips its phones with the latest versions of the operating system and multifunctional firmware, trying to keep up with the generally recognized leaders in the Android smartphone market.

However, few of us know that already quite convenient Huawei phones can be made even better by fine-tuning them to suit your needs. What we can configure in the phone’s main menu is only the tip of a huge iceberg; the rest is hidden from users in order to avoid device failure. However, people who deal with mobile phones not just at the user level, but, for example, work in a service, can easily access advanced settings on almost any phone using the engineering menu.

Looking ahead a little, it’s worth saying that inexperienced users really shouldn’t go into this “forbidden forest”, so as not to simply ruin their device through carelessness. But if you are confident in yourself and think that you understand technology at a sufficient level, then the Huawei engineering menu is exactly what you need to fine-tune your device as much as possible.

The engineering menu gives the user access to manual configuration of almost all phone parameters. Typically, engineer mode is used by developers at the stage of final configuration of the device before it goes on sale. With its help, they check the device for various errors, malfunctions, and also check the functionality of all device systems. In addition, the engineering menu contains detailed information about the capabilities of the device and its programs.

The engineering menu is built directly into the Android program, however, on some phone models, developers intentionally remove it from the phone after final testing. In such cases, it will be problematic for the owner to configure the device “for himself” directly from the phone and he will have to either use special programs that can be downloaded, for example, on Google Play, or use firmware from third-party developers.

The engineering menu for Huawei smartphones is usually always in place and is never deleted, so if you were unable to get into these settings the first time, then most likely you simply did not take into account the unique features of your device. It is also worth repeating once again that if you are not sure of what you are doing, and working with such menus is new to you, then you should carefully consider this step. Remember that unsuccessful settings in the engineering menu may not improve the functioning of the smartphone, but, on the contrary, make it much more inconvenient, and if you change the system settings, you lose the warranty and bear full responsibility for the device yourself.

How to get to the engineering menu?

In order to get into the engineering menu of a phone based on the Android operating system, you need to enter a certain secret code in the phone dialing menu. Most often on Android devices you need to dial the combination *#*#3646633#*#*. This code is suitable for most Android smartphones, but sometimes developers can change it, for example, entering the Huawei engineering menu most often occurs using the codes *#*#2846579#*#* or *#*#2846579159#*#*.

Also, codes can often change depending on the specific device model and the type of single-chip system used in it. Also, it often depends on the phone’s single-chip system whether the smartphone even has a built-in engineering menu or not. So, on devices with MTK processors, such a menu is available on almost every device, but on devices equipped with Kvalcom processors, on the contrary, in most cases this menu is completely absent.

The code should be applied immediately as soon as you enter it on the call screen, but on some phones you sometimes also need to press the call button for the code to work properly. It is also worth noting that the code must be entered and not copied, since otherwise it will not work. It is also quite useless to save such codes in the phone book, that is, manual entry is a prerequisite for the code to work.

Commands for accessing menus

If you don’t know how to enter the Huawei engineering menu — smartphone, or you can’t do it, then this is not a reason to be upset. Most Huawei devices support so-called “service codes”, which partially duplicate the functions of the engineering menu.

Service codes have been used in mobile phones for a very long time and many of them appeared long before the first Android smartphones came out. However, although such codes repeat some of the functions of the engineering menu, using them is not at all as convenient and completely unsafe. Some of them can literally delete all data stored on the phone or disable certain functions of the device. So, if you are not one hundred percent sure what a particular code means, we do not recommend that you use it for the simple reason that they may interfere with the normal functioning of your phone.

Now let's look at some examples of the most useful, in our opinion, engineering codes:

1. *#06# — using this code you can find out your IMEI address.
2. *#*#4636#*#* - This code provides you with some information about the phone, namely: device data, battery information, battery statistics and phone usage statistics.
3. *#*#7780#*#* - this code resets settings such as Google account data, system data and settings, downloaded applications to the factory state.
4. *2767*3855# — this code performs a complete formatting of the smartphone. So think twice before using it.
5. *#*#34971539#*#* — this code is intended to obtain information about the smartphone’s camera.
6. *#*#7594#*#* — used to change the on/off button modes.
7. *#*#273283*255*663282*#*# - Using this command, you can open the file copy screen and use it to backup your most valuable photos or audio recordings.

There are also many other service codes that allow you to very carefully check and configure your telephone. However, due to the fairly large number of them, this will perhaps be a topic for a separate article, and we will move on.

Engineering menu functions

Huawei's engineering menu offers a wide variety of settings for experienced users. On most models of phones from the company from the Middle Kingdom, volume adjustments, camera settings, navigation, telephony and many other functions are available that you can change at your discretion.

In fact, there is nothing complicated in the adjustment itself. Just look for the parameter you need, for example, volume level, open it and experiment with the values ​​until you achieve the ideal result for you. However, let us remind you once again that you should only change those parameters that you are sure of, otherwise you risk getting not a perfectly fitted smartphone, but a piece of irritating plastic.

Telephony

One of the main points that catches your eye when you first enter the engineering menu of an Android Huawei smartphone , This is the telephony menu. In this menu you will have access to many useful settings, including such important items as:

1. Auto Answer. Here you will be able to enable or, conversely, disable auto answer to an incoming call.

1. Band Mode. Here you can manually select frequencies for the GSM module. This menu will show you all the frequencies your phone supports. You can uncheck those bands that your mobile operator does not provide, which will ultimately save your battery power.
2. CFUSetting. This option enables or disables conditional call forwarding.
3. AT Command Tool. A utility for developers that supports AT commands.

That's probably all, dear friends. We hope this article was useful to you and answered most of your questions. We wish you excellent setup of your phone, and may it bring you only pleasant emotions.

Sound is an important characteristic of any communication device, because a lot depends on it: sufficient volume allows you not to miss a call, and the correct microphone setting allows the interlocutor to hear you loudly and clearly. But what if the maximum sound volume of your headphones, microphone or speaker is not enough? Sound settings change spontaneously, and the maximum volume is limited by an automatic “safe limit”?

There are several ways to increase the sound volume on Android: using standard sound controls, using equalizer programs, and also through the engineering menu. But first things first.

An easy way to control the audio level on your phone

The fastest way to adjust the volume on an Android device is with the Volume+ and Volume- keys, usually located at the end of the device. They are responsible for the volume of the active mode. If you press a key on the main screen (desktop), the volume of notifications is adjusted; in a game or player, the media volume is adjusted. Most often, in the pop-up window with the volume slider, you can select “More” (usually looks like a down arrow) and adjust the volume of all possible sounds on the device.

Other settings options are available at: “Settings” menu, “Notifications” item. There are several standard sound profiles to choose from; you can change the “General” profile to suit your needs.

Photo gallery: setting up sound on Android in detail for smartphones and tablets

Setting the ringer volume Setting the volume of media effects The pop-up window can be expanded by clicking on the down arrow
In the menu, you must select “notifications.” The “Notifications” item presents basic sound settings, profiles and alert modes. The “General” profile is available for detailed settings.
On different device models, additional options for improving sound may differ. The number of options, except for the device model, depends on the Android version

In addition to the standard settings, in different versions of Android you can find other useful functions: options for improving sound for headphones, increasing speaker volume, surround sound effects and others.

How to improve the quality and volume of sound using programs

Typically, Android devices have standard applications for sound control - equalizers. But if the manufacturer did not bother to add such a program, or the standard one does not meet all the requirements, dozens of analogues for every taste are always available for download from the official Play Market application store. Let's look at the main ones.

Volume Booster Plus

When you need to increase the Android volume level, but there is neither time nor desire to go into the engineering menu, the Volume Booster Plus program will come to the rescue. The lack of Russian language in the interface will not prevent you from using the program: after the first launch, the application will inform you that it will analyze the characteristics of the device and select the optimal settings for amplifying the sound. To do this: press the Start keys successively, Next twice, then Boost, and then wait for the setup process to complete. The result will be a window with the title Success. All! The device volume is increased by 2 by the specified percentage. You can close the application.

Increase ringtone volume using Simple EQ

For detailed sound settings, Simple EQ is one of the simplest free equalizers on Android. Increasing the volume can be achieved by controlling the frequency sliders 60 Hz, 230 Hz and others. Bass and stereo effect enhancement is also available. After the first launch, the program remains running in the background and provides the specified level of volume and sound quality in all usage scenarios.

In the image: setting up sound on Android using the Simple EQ Equalizer

You can download the program from its official page in the Android application store - download Simple EQ Equalizer.

How to make a loud call through the engineering menu

The most advanced volume settings are available through the device's engineering menu.

Engineering menu (mode) is a special service program on devices with the Android operating system. Developers use it to finalize the device, make final changes, check the operation of various sensors, and perform system testing. The same application is used to obtain a large amount of system information, and among other things, helps to fine-tune the sound volume.

It is worth noting that an ignorant user should not wander around the engineering menu without a clear goal. A careless “poke” or a tick in the wrong place can both format the device and deprive the radio module of its treasured frequencies: the device will stop “catching” the Internet or making calls. But if you do everything according to the instructions and do not deviate from the letter of the manual, you can adjust the sound volume in no time.

You can enter the engineering menu using the service code or through an intermediary program - MTK Engineering Mode (only for devices with an MTK processor).

You can download the program to enter the engineering menu from a device on an MTK processor from its official page in the Android application store - MTK Engineering Mode.

Video instructions on how to increase the speaker volume:

You need to enter the service code in the dialing field (in the “dialer”), which one depends on the device manufacturer.

Table: service codes for different models of Android devices

After which the engineering menu will open. In it, by swiping from right to left, you need to go to the Hardware Testing page and open the Audio item.

Photo gallery: how to add sound using the Android service menu

There are several items in the Audio section, we will focus on the first five:

• Normal Mode - is responsible for the volume level in normal mode, without headphones or other audio devices;
• Headset Mode - operating mode with a connected headset (headphones, portable speakers, etc.);
• LoudSpeaker Mode - speakerphone mode;
• Headset_LoudSpeaker Mode - hands-free mode with a headset;
• Speech Enhancement - conversation mode (without a headset).

Is the music coming from the speaker not loud enough? Your choice is Normal Mode. Can't hear your interlocutor? Click Speech Enhancement. Is the sound from the game wheezing in your headphones at maximum volume? Headset Mode. And so on, depending on the circumstances.

When you have decided on the mode, tapping on it takes you to a settings page with several values.

Photo gallery: how to change the sound of a microphone, headphones, strengthen conversational and music speakers on Android

Type - the list contains the type of equipment being configured, its items mean:

• Sip - volume of Internet calls;
• Mic - microphone volume;
• Sph - speaker volume (for talking on the phone);
• Sph2 - second earpiece (rare);
• Sid - do not touch (problems are possible!);
• Media - playback volume of media files (Music, Games, Video);
• Ring - ringer volume level;
• FMR - FM radio volume.

Next is a list of volume levels - Level, usually there are seven of them. Each level corresponds to one press of the volume key. Level 0 is the quietest, and Level 6 is the loudest signal level. Here you can set your values, in the input cell opposite the inscription “Value is 0~255” (the specified limits may differ from device to device). Accordingly, the lower the value in this cell, the lower the volume. After making changes, you must click the Set button and the settings will be saved.

The bottom one in the window will be “Max Vol. 0~160", the value in the input field is responsible for the maximum possible volume, one for all Levels.

Attention! Before changing the default settings, overwrite the factory settings or save screenshots (usually a snapshot can be taken by pressing the Volume Down key and the Power key at the same time) so that if the change is unsuccessful, you can return to the previous settings. It is also highly recommended not to use maximum values: try to limit yourself to an increase of 10–20 points. Otherwise, the risk of speaker failure increases: the appearance of noise, distortion, or completely turning off the speaker or microphone of the device.

When you have decided on setting the required sound mode, you can close the engineering menu and reboot the device, then all changes will be applied.

What to do if the volume limit turns on - how to remove it

Some device models, as well as versions of the Android operating system, automatically limit the maximum sound volume when you connect headphones or increase the volume above a certain value, in this case, you can use the Volume Boost program or its analogue. Just install, launch, and in the Settings tab check the box next to Auto Start (this will allow the application to load automatically and always run in the background). There you can also check the box and activate the application control widget, and by placing it on the desktop, you can independently turn on and off the volume limit so as not to keep the program always active.

Eliminate spontaneous volume changes

Sometimes users encounter the rare problem of spontaneously switching the volume level; this can be caused by several factors:

• Most often, this problem is found in owners of overly “smart” Samsung or HTC devices, as well as little-known Eastern brands. First of all, in the “Settings” > “Sound” menu, you need to check the presence of the “auto volume control” item. The name may differ and contain phrases: in the case, in the pocket, on the table. If you have problems with sound, try starting by disabling such options.
• Owners of older Samsung smartphones, such as the Galaxy S4, can find malicious settings at: Settings > My Device > Calls > Ring Loudly in Bag.
• Also, similar settings can be in the “Settings” > “Accessibility” menu and called: Smart Case, Auto Volume, Pocket Mode.
• If the device is equipped with a protective bumper or case, it would be a good idea to check whether the physical sound control keys are stuck.

But remember! If on your device, when you connect a headset (headphones, portable speakers), the message “safe limit” appears and reduces the maximum volume, this limit is set by the manufacturer for a reason. First of all, we are talking about the health of the person using the headset. Protect your hearing.
