How to enter the phone's engineering menu?

Not every person who has his own mobile phone understands thoroughly the various features of the work of his device and the intricacies of its customization. In particular, many do not know how to enter the engineering menu of the phone and why you should do it at all. In fact, the engineering menu often becomes one of the main tools of specialists of various service centers, which eliminate all possible flaws in the firmware or any malfunctions in the internal program of the device.

How to enter?

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 a specialized utility MTK Recovery.

Audio

There are several categories in this section:

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

Before choosing any possible values, you should make sure beforehand that this will not cause you to encounter any sound problems afterwards. In the majority of cases, it is highly discouraged to do this because the maximum settings can trigger the appearance of a rattling effect and a number of other jamming, as well as create an extra load on the speakers, which provokes their faster failure.

In addition, never forget that before changing any settings, it is mandatory to record the ones that were installed by default, so that in case of any problems you could quickly return them to the original value.

Normal Mode

After you figured out how to enter the phone's engineering menu and what it has the main paragraphs, go to Normal Mode. Here you will see a menu in which there are four positions, among which the first item is the profile number. Paragraph FIR - 0 - you need to leave and do not touch, then go below, in the following characteristics.

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

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

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

If you thought that the music is too quiet in the headphones or the radio, then in this case you can slightly correct the profile for the headset, but do not forget after that to restart the phone in order to keep the settings.

How to change the volume of negotiations?

Speaking volume through the engineering menu changes as follows:

• We go in the menu.
• Select Audio.
• We find the Speech enhancement characteristic, which is responsible for how well we hear the subscriber on the other side.
• Press the button Common Parameter, then select Normal Mode.
• Now look at the Parameter (0) characteristic, then set Parameter - 6.
• Begin to edit this parameter and change it from the standard 400 to 1, then press the Set key.
• Now, audibility will become even more than acceptable, and in some cases even it is necessary to reduce the volume (often such an effect is provided by the engineering menu of Samsung).

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 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 such characteristics, you will get an acceptable loudness while listening to any material. In particular, this allows you to make both the engineering menu of Samsung modern models, and the menu of most other phones.

Service menu

In the service menu there are also several basic items that may interest users:

1. BatteryLog . Engineering menu FLY and other modern phones allows you to get extremely accurate information about the state of the battery, including temperature, voltage and other fine parameters.

2. TouchScreen . Quite a broad parameter, which has the engineering menu FLY and other manufacturers that produce modern touch phones. There are several submenus in this section:

• HandWriting . Quite a simple option - to draw a finger on the screen, which allows you to check how well the sensors respond to touching them.
• PointVerification . Allows you to diagnose screen calibration, and when you click the appropriate button it shows whether there are any errors and, if so, how much they are deviated from the desired value.
• LineVerification . Almost the same as the previous point, only here from one point to another drawn lines.
• ShakingVerification . Check "shaking".

3. Camera . The Android engineering menu in the Camera section includes several submenus that allow you to test or change various camera characteristics:

• AF EM. Selects the test for the camera with autofocus.
• Raw Capture. Launches the mobile device testing procedure of the same name.
• Start Preview. Allows you to view the image on the screen from the camera.

4. Wi-Fi. The submenus of this section are:

• Tx . Tx register tests.
• Rx . Tests of registers Rx.
• EEPROM . Specialized firmware adapter, which also allows you to enable or disable its functions through the addresses. If you use the Android engineering menu, it is strictly recommended not to change any parameters in these characteristics. After such an intervention, it will not be easy to restore them for qualified specialists, even if you try to make a backup as "save as file", because for some reason all values are stored in zeros.
• Temperature Sensor. Allows you to check the temperature of the adapter during its operation.

5. Bluetooth . Virtually every engineering menu of Philips and other modern phones has this paragraph, but at the same time it may not be available in some older or specialized models of devices. Includes several submenus:

• TX Only test. You must specify a value, then click [menu] and Done. Next, the Bluetooth Tx registers are tested.
• Test Mode. Allows you to activate the test mode.
• NetworkInfo. More information regarding RR. In this case, you should select which parameters you are interested in, then press the Menu button, select the Check Information item, and browse the data.
• AutoAnswer. This feature provides the ability to automatically pick up the handset when an incoming call through the engineering menu. Settings are often absent and you can only enable or disable this feature.
• YGPS. Testing, as well as providing information to the user regarding YGPS.
• AGPS. Often the only menu that is provided in Russian. Allows you to configure AGPS.

How to increase the volume?

There are several ways to solve the problem.

Initially, you need to go to Audio, then select one of the following menus: Headset Mode, Normal Mode or Speech Enhancement.

Let's go to Normal Mode, then in the Type list look for the Value paragraph. All values here must be set in the range from 0 to 255, with the smaller the value you set, the higher the volume of the sound.

additional characteristics

In the Type section, you can also change other characteristics that interest you, from the Speech volume to Speech to the Key tone. Again, in all parameters, the value must be set in the range from 0 to 255, after which the Set button is pressed, which saves the characteristics. Precisely the same procedure is also set in the Headset Mode if you want to adjust the volume in your headphones in detail. If you are a fan of a sufficiently high volume that the phone can not initially provide to you, then in this case the optimal values will be from 1 to 5, but not 0.

Immediately worth noting is the fact that here are not specific loudness values, and only the principle is described. Specific values will directly depend on the characteristics of your speaker and microphone, for, for example, those settings provided by the engineering menu of Explay can bring the parameters an order of magnitude higher than the capabilities of your phone, so that, when trying to meet these parameters, it can simply break down. Consider this and try to choose the real characteristics that can meet your needs.

How to check?

In most phones, the engineering menu provides a dedicated Ring Tone that can be used to listen to any standard tunes directly from the engineering menu in order to determine how much we have changed the volume. Of course, it's best after all the settings to call someone and "live" to check the settings, but if you try 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 negotiations

The adjustment via the engineering menu of the volume of negotiations is carried out in the above-described service menu. 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 all the actions manually, since there is no need to type a large number of digits. After all, only the values that will be optimal, sometimes have to be selected within a few hours.

After that you can dial different numbers and check how well your interlocutor and yourself are heard.

Explay Features

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

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