Engineering menu "Android": description, settings

The acquisition of a new smartphone or tablet is a real holiday for many. Each owner expects that the gadget will be pleased for many years with its reliable work and lack of any problems. And regardless of who is the assembler, and which management system is installed.

However, as it often happens, modern mobile devices can hardly be called ideal, because after a time after the start of use, the moments that the owner wants to fix are revealed, by somehow improving the program part of his mobile assistant to the ideal. Of course, in my understanding. One of the available tools is the engineering menu "Android".

Secret settings that everyone knows about

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

A few important points

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

First, the CPU must be necessarily produced by MediaTek (or MTK). On inexpensive models Spreadtrum, for example, SC-6825, popular Snapdragon from Qualcomm, various Tegra NVidia and Intel try to run the engineering menu "Android" useless. It is not there. Performance can not be achieved, even if it is prudent to install the appropriate application.

Secondly, various modified operating systems, for example, popular in some circles of CyanogenMod, do not allow to run 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) should be present among the programs, even being hidden from the standard explorer. So, some manufacturers of mobile devices after performing the settings of the software part simply delete the engineering menu "Android". The description and recommendations for use in this case are useless, which is obvious.

Secret combination

You can get into the settings of the engineering menu on "Android" in several ways. It is impossible to say which of them is better, since a direct comparison is incorrect. Therefore, consider them in turn.

One of the most "ancient" versions, which was used even in the first models of smartphones and tablets, is that the user in the dialer program (the so-called dialer) does not dial the subscriber's number, but the special code of the engineering menu "Android" by analogy with the verification Funds on the account. If the combination is recognized and accepted, the setup application starts. Some mobile assembly 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.

The usual way of access

Using a secret combination is not always convenient, if only because the order of characters is easy to forget. Also, in the case of a modified set, it is easier to use the program, rather than look 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 is usually no problem with the search and installation. At the time of this 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 get on his gadget root-rights. For this, there are a lot of applications, for example, KingRoot, SuperSu, etc. In this article we will not talk about the nuances of working with a ruled device, since this is a separate three-dimensional topic. After starting the application, select the third item, named Engineer Mode (both in Russian and English versions), and in the opened window - "Work with MTK". If you are asked to provide root-access, you must answer in the affirmative.

How to restore access to the mode for engineers

In the event that the manufacturer of the mobile gadget takes care of the security of the operating system, by prudently removing the configuration program, it can be reinstalled. To do this, it is necessary to find an installer in the network that restores EngineerMode.apk and install it.

The exact name we do not indicate because of the abundance of clone analogs. For example, one of them is called "Engineering mode". You can also simply copy the missing file to the system folder that is located on the system \ app path. After that, you can use any method for access: either by dialing a number or by directly calling from the program interface. Note that these operations require the rights of rut.

Features miracle program

Setting "Android" through the engineering menu, in spite of the ambiguous attitude to this gadget owners, makes it possible to solve several important tasks. In particular, adjust the sensitivity of the microphone, cure the "childhood illness", manifested in insufficient volume of the system speaker, reduce the battery power consumption, disabling the scanning of "extra" ranges, and reduce the search time of satellites by the global positioning system receiver. We will dwell on the above functions in more detail, since they are the most in demand.

Call volume

Increase the volume of the call is very simple. To do this, you need to select the "Audio" section to the right. A list of modes appears. For the system speaker is responsible LoudSpeaker Mode, a sub-section of Ring. The parameter in the first window should not be changed, but in the second one you can assign a higher value. Developers can initially be set to the index of 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.

Frequencies of mobile operators

To optimize the power consumption of a mobile communication device, you can turn off scanning of "extra" frequencies. In our country, when operating in conventional 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, select the Band Mode item, alternately enter the settings for SIM-1 and SIM-2 and remove / put the desired notes. Press the Set button to confirm.

How to improve GPS? To improve the work of global positioning, you need to turn on Wi-Fi, in the engineering menu "Android" select the Location item, proceed to the Location Based Service and open the EPO. Here you need to make sure that there are checkboxes on the Enabled and Download items (if they are present). After that, you should return to YGPS and in the information section click "Full", "Cold", "Restart" one by one. Next, you need to select the "Satellites" item and wait until the answer is recorded (green dots on the map). All takes from 2 to 5 minutes. After that, it remains to exit the menu, close the program and restart the gadget.

Summing up

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