Adjusting sound for android through the engineering menu. What is an engineering menu? With the help of specialized programs

Modern smartphones are aimed at universalism - one device combines qualities that would have required several different ones five years ago. But it happens that the volume of the built-in speakers is not enough, and this is of interest not only to music lovers, but also to ordinary users, since sometimes it is simply impossible to hear a call on a noisy street.

This article will cover the main ways to increase speaker volume on Android devices.

Using standard system capabilities

To adjust the sound, use the keys located on the side edge. Sometimes they can just jam or be used in the wrong interface, for example, in some applications, the side buttons perform different functions. Try to set the volume directly in the settings by selecting the "Ringtones" or "Volume"... Also, in some versions, the menu opens after pressing the adjustment keys.

Please note that there are several volume profiles on Android:

• Call.
• Multimedia.
• Messages.
• Alarm.
• There may be others depending on the firmware.

When you press the knob, only one of them is adjusted, while the others remain the same, in particular, the call volume changes on the desktop, and the music volume in the player. One of the call profiles can also be edited.

Through the engineering menu

Advanced users can try, which provides an extended list of tools. For each device, the input combination is different, you can check it on the manufacturer's website or in the technical support service, or read our instructions on Android. Also, the Mobile Uncle utility is used as an alternative method.

After successfully entering this menu, in the Hardware Testing section, select the Audio item and try to slightly increase the volume. But remember that too coarse settings can damage the speaker. Then, check if it worked.

In case of failure, remember to revert to the previous values.

With the help of specialized programs

The most popular speaker setting tool is Volume +... It is free and available for download, but the interface, unfortunately, is only in English.

Another way is to use an equalizer. The jetAudio program has good functionality. Find the item “Volume” and increase the settings to the maximum.

The last program we reviewed, which we can recommend to you, works in automatic mode and does not require any effort from the user, but there is also a significant drawback - the effect is not felt on all devices. It's about the Volume Booster Plus app... Download, install and click on the speaker in the main menu, automatic optimization will start. If the sound does not become louder, then the application does not work on your device.

It is important to remember that the constant use of the speakers at maximum volume, especially if changes have been made to the parameters set by the manufacturer, contributes to the loss of the device's qualities and accelerates its breakdown. This should be done only if necessary.

You should also play only compositions in high quality, because at high volume, interference in the sound track is especially noticeable, but if this does not help correct the sound, then the reason is in the speaker itself, probably, it simply cannot cope with such a volume, but you can try to change the player.

Hardware methods

First of all, it is worth deciding on the task, remember that not a single smartphone, even the loudest, can replace musical equipment, it will not work to arrange a disco with it.

• You can achieve really loud sound using portable speakers, some models are very compact, they can even be fixed directly on the device's case by connecting via a 3.5 mm jack, however, you have to sacrifice their appearance.
• An external USB sound card can be purchased. It spoils the design of a mobile device less, and almost does not change its dimensions, but a high-quality device that can significantly increase the volume will cost a lot, so this is rarely used and only on top models.
• Another way is the laws of acoustics. With a special smartphone stand, you can achieve an increase in volume due to the reflection of sound waves from the surface. But sometimes even this is not required, take a closer look at how you hold the device, if the rear speaker grill is blocked by your palm or finger, then it is enough to remove them, the same happens when the gadget is lying on the table.

Troubleshooting Android

The most common reason is a factory defect. The speaker may initially not work correctly. If someone you know has a smartphone of the same model, then you should compare the sound. The test should only be performed on one MP3 track and in the same player with the maximum volume level, otherwise the results may be incorrect.

When there are problems with the volume of the headphones at the same time, then the cause may be a malfunction of the media converter or codecs. If two weeks have not passed since the purchase, the device can be returned to the store or replaced with another.

Problems can also occur with the software: sometimes using third-party codecs or a player can solve the problem. Also, the sound of a particular song can be very different, you need to download tracks in maximum quality, preferably in FLAC format.

If the device has been used for a long time, and previously there were no problems, then the reason may lie in the contamination of the speaker grille.... Carefully remove the back cover and check for dust or dirt accumulation on it. If they are present, then turn off the device and remove the battery. Next, you need to carefully remove the debris using a damp cloth and let the lid dry a little. The front speaker is more difficult to clean as dirt can seep into the openings. To do this, you will need to dismantle the case, if necessary, it is better to contact the service.

If this does not help, then perhaps the speakers simply lost their former power. Manufacturers of budget models often save on acoustics, especially for tablets. Unfortunately, it will no longer be possible to restore them, you can replace the speaker itself with a new one, or even more powerful, but in this case, you need to pay attention to compatibility. The improvement should be carried out exclusively by a professional, otherwise damage is possible, which can lead to a complete failure of the sound card.

Hello.

Unfortunately, the volume on the phone (or tablet) is not always sufficient: it is not so rare to have to listen ... Even worse, many people miss calls (sometimes important) when they are on the street or in some noisy place (just quiet the bell is almost inaudible).

In general, the reason for this "behavior" of the phone can be as those. malfunction and software (on some devices, developers deliberately underestimate the maximum possible sound for the sake of user safety - after all, too loud sound can cause hearing problems!). Well, since it was programmatically limited, it means, if you wish, this restriction can be removed!

Actually, in this article I want to show several options for how you can solve the problem of too quiet sound on devices running on Android.

Note! By the way, if you have weak sound only when playing some multimedia files (and in other situations everything is fine), I would recommend trying alternative audio-video players first:

Using the settings menu

I want to start with the elementary, despite possible objections ... (it's just that there is a little confusion with this, so it's clearly worth noting).

Volume control in Android (when you press the side buttons on the phone case) can be carried out both for a specific application separately and globally (general volume). For example, if you watch a video and turn up the sound, then the volume will be increased specifically in this application, the call volume will not increase from this!

In general, for detailed sound settings on Android devices, you need to open the parameters, section "Sounds and notifications" and then move the slider to the right for the required line (for example, you can change the volume of ringtone, notifications, music, video, alarm, etc.). See screenshot below.

With the help of specials. applications

Because the problem of low volume is quite popular, many developers have released specials. applications that can use some of the "hidden" capabilities of your device. In principle, for their work (as a rule) you do not need root rights, so you can use it without fear of "spoiling" something in the settings ...

A simple free application that will help increase the sound of your phone speaker (or headphones). Can be used when watching movies, listening to audio books, music.

Note that before using the application, it is recommended to unscrew the system sound slider by 100% (and then boost ...).

Developer warning: be careful! Increasing the volume can damage the device speaker (or your hearing). Carry out the addition in small steps (testing each change), without sudden jerks to the maximum!

Sound booster

Sound Booster differs from other applications of this kind in that it processes sound even before it reaches the sound card (i.e. acts as a kind of intermediary). Of course, with the help of this technology, it is possible to increase the volume in any other application, games, listening to music, watching movies, etc.

The application allows you to increase the sound up to 500% of the original level! Recommendation: do not add immediately to the maximum, go in small steps, testing each addition ...

It is also worth noting that a special is built into the application. filter that helps to eliminate hiss and jitter of the sound track, after processing and amplification. In general, I recommend you for review!

Sound amplifier

Screen from application developers

Another free and very simple application for amplifying sound on Android devices (I note that this application is completely in Russian, which pleases).

Of course, like its counterparts, it allows you to adjust the sound when playing media files (music, video, etc.), audiobooks, etc. It supports both headphones and system sound.

Using the engineering menu

Android smartphones have a hidden engineering menu, which is used by developers for final testing of the device (including fine-tuning the sound). As a rule, the device is never tuned to maximum volume, and a potential reserve of 20-30% (sometimes more) remains.

Those. if you go into this engineering menu yourself and make "small" manipulations, you can significantly increase the volume of the phone.

I note that for this procedure, root rights are not needed (which means the risk of spoiling something is reduced), but I still urge you to be careful and change only those parameters that you know ...

Entrance to the engineering menu

To do this, you must enter a special. code. Each device (depending on the manufacturer and model) may have its own. I have collected some popular options in the table below. (if your device is new, you may need to refer to its instructions, official website of the manufacturer).

Note: enter the codes at your own peril and risk (despite the fact that they are collected, including from official sources from manufacturers).

Entering engineering (sometimes called service) menu, open the "Audio" section (the "Hardware Testing" tab). Next, pay attention to a few points (see screen below):

1. Normal Mode - normal (general) volume level;
2. Headset Mode - the level responsible for working with headphones, headsets, etc .;
3. LoudSpeaker Mode - speakerphone setting;
4. Headset_LoudSpeaker Mode - speakerphone mode with a headset;
5. Speech Enhancement - the level responsible for the talk mode (without a headset).

Enter the desired menu (in my example, Normal Mode).

In the Level column, select each of the 14 levels in turn (you need to click everything) and increase the "Value" (by 15 points, for example) and "Max. Vol" (up to 155-160). By the way, "Max. Vol" cannot be higher than 160.

I note that after setting the numbers - click on the button Set (translation: install / ask).

Note: in the "Type" column, you can specify Sph (this is the sound of the spoken speaker).

To adjust the volume of an incoming call in the "Audio" section, open "LoudSpeaker Mode", and set "Ring" in the "Type" column. Further, by analogy with the example above.

After setting the settings, exit the engineering menu and restart the phone. In such a simple way, it is possible to raise the volume by 15-20% (and more).

Alternative solutions in the comments are welcome ...

Happy work!

Often in Chinese (and certainly not only Chinese) Android-based phones in the engineering menu, far from optimal volume settings of the speaker, headset (headphones) and microphone are set, their correction will be discussed in this article.

How to get into the engineering menu of an Android phone

To get into the engineering menu, open the dialing and enter a special code: *#*#3646633#*#*

Also on some versions of Android the command may work * # 15963 # * and * # * # 4636 # * # *

If your phone's processor is not MTK, then there are different options.

I will give the codes known to me for opening the engineering menu on different phones and tablets:

*#*#54298#*#* or *#*#3646633#*#* - smartphones based on MTK processor

*#*#8255#*#* or *#*#4636#*#* –Samsung smartphones

*#*#3424#*#* or *#*#4636#*#* or *#*#8255#*#* - HTC smartphones

*#*#7378423#*#* - Sony smartphones

*#*#3646633#*#* - smartphones TEXET, Fly, Alcatel,

*#*#3338613#*#* or *#*#13411#*#* - smartphones Fly, Alcatel, Philips

*#*#2846579#*#* or *#*#2846579159#*#* - Huawei smartphones

*#*#2237332846633#*#* - devices from Acer

Immediately after entering, the command should disappear and the engineering menu should open. But on some devices, you still need to press the "Call" key

A list of sections of the engineering menu of the phone will appear.

Just in case, grab a notebook and pen and take a look at the settings that were set on your phone before you intervened. You never know, anything can happen.

On my phone (based on the MTK processor), in order to get to the engineering menu, I had to install a free utility (program) from Google Play " Mobileuncle MTK Tools", Which opens access to the engineering menu (that is, it works similarly to dialing the magic combination * # * # 3646633 # * # *).

I am sure that there you will also find free applications for other phones.

Volume settings for the speaker, headset (headphones) and microphone of the phone through the engineering menu

For clarity, let's briefly analyze the volume level setting of the device:

We go into the program or type a magic combination to enter the engineering menu. Further, in the menu that opens, select the section " Engineer Mode»

A section will open in which you can select the engineering menu of the Android system (skip it), and the engineering menu of the phone itself.

We need the phone's engineering menu, so we select the "Engineer Mode (MTK)" section. This item is circled in the figure with a red marker.

A very long menu will open, through which you can get to almost any phone settings. But it is not enough to get to them, you need to know how to manage them.

Therefore, do not change what you have no idea about.

At worst, write down the parameters that were before your intervention, in order to return them back later. Let's continue!

Since we are interested in setting the sound level, select the "Audio" item, I circled it with a red marker.

And ... magic! The menu that interests us for setting the parameters of the speakers and microphone opens.

And actually why did we get into this menu? Does something work like this out of curiosity? Okay, let's continue to figure it out!

Here it is worth stopping and figuring out what all these menu items mean.

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;

LoudSpeaker Mode(loudspeaker mode) - it is activated when nothing is connected to the phone or tablet, and you turn on the loudspeaker while talking on the phone;

Headset_LoudSpeaker Mode(loudspeaker mode with a headset connected) - this mode is activated if you connect headphones or external speakers to the phone or tablet, and you turn on the loudspeaker while talking on the phone;

Speech Enhancement(telephone conversation mode) - this mode is activated in the normal telephone conversation mode, and nothing is connected to it (headset, external speakers) and the speakerphone is not turned on.

Debug Info- it is not clear why - information on backing up information or debugging it;

Speech Logger- did not fully understand, most likely, logging during negotiations or recording a conversation. 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 gets the following form: Day of the week_month_year__hour_minutes_seconds (for example, Friday_July_2016__time17_12_53.pcm).

What these files are for and how they can be useful to us is not clear. The / sdcard / VOIP_DebugInfo directory (which is the storage location for files with backup information) is not automatically created, if you create it manually, then after a conversation it will remain empty.

Audio logger- serves for sound recording, which supports quick search, playback and saving.

When entering any of the modes, you will have access to various volume settings (Type). Here is a list of the basic settings you need to know:

• Sip - settings for internet calls;
• Mic - microphone sensitivity settings;
• Sph - spoken dynamics settings (the one that we apply at the ears);
• Sph2 - settings for the second spoken speaker (I don't have one in my phone);
• Sid - skip, when you change these parameters during negotiations on your smartphone or tablet, you can hear yourself instead of the interlocutor;
• Media - setting the multimedia volume level;
• Ring - adjust the volume level of the incoming call;
• FMR - FM radio volume settings.

A list of volume levels (Level) is available under the item for selecting settings (see figure).

There are usually 7 such levels, from level 0 to level 6. Each such level corresponds to one "click" on the volume rocker of your smartphone or tablet.

Thus, level 0 is the quietest level and level 6 is the loudest signal level. Please note that each level can be assigned its own values, which are located in the cell Value is 0 ~ 255. They should not go beyond the range from 0 to 255 (the lower the value, the quieter the volume).

To change this parameter, you need to erase the old value in the cell and write a new one, and then press the "Set" button (the one next to the cell) for assignment.

Finally, below you can see the Max Vol. 0 ~ 255 (on my smartphone, for example Max Vol. 0 ~ 255, it all depends on the manufacturer). This item sets the maximum value of the volume level, it is one for all levels.

Dear friends. The name of the items may differ on different models. This is the MTK platform, so be prepared to strain your brain and search for a match in your menu. I have a Jiayu G3 phone.

My changes were applied immediately, but maybe someone needs to restart the phone for them to take effect.

Although, it seems, you shouldn't break anything, and if you don't like the changes, you can always enter the old value ..
But still..
ALL CHANGES YOU MAKE AT YOUR OWN RISK !!! Do not forget to include the thought!

P.S.: I found the font size setting on my phone. It turns out that you can still increase it!
P.P.S .: if something is still not clear, then here is a video on setting up sound in the engineering menu:

Sound is one of the most important features of any smartphone or tablet, so it is vital that the sound is loud enough and of high quality. In this article, we will talk about how to adjust the volume on Android, as well as raise the sound quality.

How to adjust volume on Android

Of course, we will not talk about professional sound tuning, but we will try to touch on the necessary basics. Sound quality can be divided into several main parameters:

• Sound volume - it should be sufficient to hear the phone ringing in a very noisy place or listen to music like from a tape recorder
• Accurate reproduction of the audio file, matching the amplitude to the desired frequency
• The amount of noise - you are unlikely to enjoy listening to a “wheezing” or “choking” speaker at full or even medium volume

And we will dwell on each of these parameters in more detail. Let's start with the latter.

Sound purity on Android

The amount of noise on Android directly depends on the hardware of your device, or rather on the audio chip and sound output device, be it a speaker, headphones or an external speaker. In devices of the upper price segment, high-quality audio chips with excellent sound performance are usually installed, and as the cost of the device decreases, the quality of the audio chip also decreases, with rare exceptions. With an external speaker, this trend continues, so it is almost impossible to reduce the amount of noise on a well-tuned device.

So we should pay more attention to the other two sound parameters on Android.

Improving sound quality on Android

The second indicator can be the most subjective, so most likely you will need to customize it for yourself. Many firmwares for Android have pre-installed equalizers, which will help in setting up Android sound. But we will consider a universal method, a special application that has proven itself well among thousands of users. Its only drawback is the need Root is right to change system files.

Let's take a closer look at the program and find out how to adjust the sound quality on Android. First, download the program and install it on your Android device. Next, let's go point by point:

• Launching the program
• Asks to update the driver, agree and select the desired sound quality - High quality, Medium and Economy (it is worth noting that the quality level affects the battery consumption)
• After choosing the quality, it will ask for permission to use Root rights, we provide
• After updating the driver, do not press anything, we reboot the device
• Now you can start setting up the sound

Viper4android allows you to achieve simply incredibly juicy and high-quality sound, even with a low initial potential of the device.

We'll go over the best customization options for this feature-rich app.

In the program, press the menu button, “ Interface”And select“ Expert”. Now you have access to all the functions of setting the sound in the application.

In addition, the program has the ability to install ready-made driver settings from such popular "enhancers" as Beats Audio, Ipod, Sony Ericsson and others. To do this, scroll down to Convolver, turn it on and select “ Pulse”, Initially of course there will be nothing there, but you can download the required configuration file ( .irs) from this link and install it in the ViPER4Android / Kernel folder in the device's memory. After that you will be able to select the installed enhancer in the item “ Pulse”. Next, we adjust all other settings to the best level to our liking.

If, after numerous adjustments, the proper effect of improving the sound quality did not follow, there may be some kind of conflict with another program. Try to disable any other sound enhancers in your firmware, and also try to enable compatibility with other players in the program settings.

Finally, let's move on to the most important question: How to increase and adjust the volume on Android? First you need to understand what volume we want to increase. This can be the volume of the external speaker, in order to better hear the call or listen to music, the volume in headphones or a headset, or the volume of the Android speaker in order to better hear the interlocutor, and maybe the volume of the Android microphone.

First, let's make sure that we have increased the volume of Android as much as possible in the settings of the device. To do this, go to " Settings» -> « Sound» -> « Volume". In this menu, you can adjust the volume of calls and SMS notifications, the volume of the alarm, as well as the volume of music and video.

It is very pleasant to listen to music through a loud speaker, especially when it is built into your phone or tablet, but in most cases, the manufacturer of Android devices does not turn the volume up to the maximum, so we have the opportunity to increase the volume of the android using various methods. One of these ways is the engineering menu. However, if you are afraid to press something wrong, it is better to use a safer method.

Unfortunately, not all smartphones have access to the engineering menu, so this method is suitable for devices based on the Mediatek processor and some others. So, to enter the engineering menu, you need to enter the code through the dialer, the codes can be found in the table below.

If your device has an MTK chipset and you have root rights, you can download the application, it will greatly facilitate the setup process.

After entering the engineering menu, you need to find the Audio section, everything is hidden in it:

• Normal Mode- in normal mode, without external audio devices
• Headset Mode- connected headset (headphones) mode
• LoudSpeaker Mode- hands-free mode
• Headset_LoudSpeaker Mode- hands-free mode with a connected headset
• Speech Enhancement- phone conversation mode

Select the desired mode for setting - Normal Mode, then you need to select the type of the configured device:

• Sip- volume of internet calls
• Mic- microphone volume
• Sph- the volume of the earpiece (for talking on the phone)
• Sph2- second earpiece (rare)
• Sid- do not touch (problems are possible!)
• Media- what we need! Media playback volume (Music, Games, Video)
• Ring- also, what you need! ringer volume
• FMR- FM radio volume

Attention! Before changing the volume settings, overwrite the factory defaults so that if the change is unsuccessful, it will return to the previous settings.

Most likely, we need the maximum level, namely 6. And we change the value to the desired one, maximum 255, but I do not advise setting it, the sound quality may deteriorate and the life of the speaker will decrease, the optimal value will be 220-240.

In the video you can see an example of setting up the program:

This method is more universal, you just need to download a program to increase the volume of Android - Volume + and run it. Next, we select the desired mod, as in the engineering menu. Speaker is an external speaker, Headset- headset, and Bluetooth- wireless headset or speaker.

• We include Speaker Modifications
• Click on Volume level
• Select the desired gain level, up to +4
• You can also boost the bass right away - Bass Enhance

That's all, in a few minutes we increased the volume of the Android to the desired level.

The Android operating platform is distinguished by its functionality, wide customization possibilities and thousands of applications that are released almost every day. However, many basic functions, such as speaker volume, may not work correctly even with devices that have just rolled off the assembly line. In this essay, we will take a closer look at the question of how to increase the sound on Android.

Increase methods

There are various ways to raise the maximum audio limit. Let's describe each of them:

1. Using standard tools in the device itself. To do this, go to the settings, then "Melodies and volume"

   and select the "Volume" parameter

   In this menu, you can configure the settings for ringtone, messages, media and alarm. If you need separate settings for each profile, then you need to go to the "Sound Profiles" menu,

   and set the required values.

2. The second way to increase the Android volume is through. It is activated in each device in a different way. You can find out the combination for entering in the instructions that come with the kit, or in the support service from the manufacturer. Further, after activating this mode, you need to go to "Hardware testing" - "Audio" - select one of the modes in which you need to increase the volume, and try to slightly increase the value. After that, exit the engineering menu, check what happened, and experiment further.
3. Before you can increase the volume on Android in this way, you need to obtain superuser rights. Install the special utility Mobile Uncle with them, which can be found here. Go into it, select "Engineering Mode",

   there, too, select the "Hardware testing" tab

   "Speech enhancement" is responsible for the speaker when talking with another subscriber.

4. Another way to increase the speaker volume on Android is the dedicated Volume + utility. You can find it by following the link. The program does not work with all devices. To use it, go to the "Speaker Settings" or "Headset settings" menu

   and use the "Volume level" setting.

Sound amplifier

Consider another interesting program - volume booster for Android - Volume Booster Plus. It is downloaded from the link. After installation, you need to launch the application. It's very easy to use: in the main menu

the speaker is shown. If you click on it, an optimization will be performed and the speaker volume will increase by more than 20%. This program does not work on all gadgets.
