Getting a new smartphone or tablet is a real treat for many. Each owner expects that the gadget will delight for many years with its reliable operation and the absence of any problems. Moreover, regardless of who is the collector and what control system is installed.
However, as often happens, modern mobile devices can hardly be called ideal, because after a while after the start of use, moments are revealed that the owner wants to fix, in one way or another, finalizing the software part of his mobile assistant to the ideal. Of course, in your understanding. One of the available tools is the Android engineering menu.
Secret settings everyone knows about
At the final stage of configuring the software component of a gadget running a 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 operation of the device,perform technological tests, 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 spend only a few minutes searching for recommendations.
A few important points
Nevertheless, not all mobile devices can be entered into the Android engineering menu. In order to take advantage of its features, you need to make sure that the gadget meets certain requirements.
Firstly, the CPU must be manufactured by MediaTek (or MTK). On inexpensive Spreadtrum models, for example, SC-6825, popular Snapdragon from Qualcomm, various Tegra NVidia and Intel, it is useless to try to launch the Android engineering menu. It is missing there. It will not work even if you prudently install the appropriate application.
Secondly, various modified operating systems, for example, CyanogenMod, popular in some circles, do not allow you 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 (file) itself mustbe present among programs, even being hidden from the standard explorer. So, some manufacturers of mobile devices, after making the settings for the software part, simply delete the Android engineering menu. The description and recommendations for use in this case are useless, which is obvious.
Secret combination
There are several ways to get into the settings of the engineering menu 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) does not dial the subscriber's number, but a special code of the engineering menu "Android " by analogy with checking the funds in the account. If the combination is recognized and accepted, then the configuration application is launched. Some mobile device assembly companies use their own modified code, so the standard set does not always work. Otherwise, to call the menu, you should dial the following character order without spaces - 36 46 633. It's that simple.
The usual way to access
Using a secret combination is not always convenient, if only because the order of the characters is easy to forget. Also, in the case of a modified set, it is easier to use the program, rather than looking for the correct order of characters. One of the most famousapplications - this 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 this writing, the current version is 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 root-rights on his gadget. There are many 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, select the third item, called Engineer Mode (both in Russian and in English versions), and in the window that opens - "Work with MTK". When prompted to grant root access, you must answer in the affirmative.
How to restore access to engineer mode
If the manufacturer of the mobile gadget took care of the security of the operating system by prudently deleting the configuration program, then it can be reinstalled. To do this, you need to find an installer on the Web 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 along the system\app path. After that you canuse any method for access: both by dialing a number, and by direct call from the program interface. Note that these operations require root rights.
Features of the miracle program
Setting up "Android" through the engineering menu, despite the ambiguous attitude of gadget owners to this, makes it possible to solve several important tasks. In particular, adjust the sensitivity of the microphone, cure the "childhood disease" manifested in insufficient volume of the system speaker, reduce battery consumption by turning off the scanning of "extra" bands, and reduce the time it takes for the global positioning system receiver to search for satellites. Let's dwell on the above functions in more detail, since they are the most in demand.
Ring volume
It's very easy to increase the ringer volume. To do this, select the “Audio” section with a swipe 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 one you can enter a higher value. Developers can initially set an indicator 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 disable the scanning of "extra" frequencies. In our country, when working in conventional 2G / 3G networksstandard frequencies are 900 and 1800 MHz. The other pair, 850 and 1900 MHz, is the American standard. To enable or disable, you need to select the Band Mode item, go to the settings for SIM-1 and SIM-2 one by one and remove / put the desired notes. Confirmation is pressing the Set button.
How to improve GPS? To improve the work of global positioning, you need to turn on Wi-Fi, select the Location item in the Android engineering menu, go to Location Based Service and open EPO. Here you need to make sure that there are ticks on the Enabled and Download items (if they are present). After that, you should return to YGPS and in the information section, press "Full", "Cold", "Restart" one by one. Next, you need to select the "Satellites" item and wait until the answer is fixed (green dots on the map). Everything 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 running the Android operating system opens up opportunities for the owner of the gadget, the use of which allows you to configure the device in the best way. Often this is 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 the tablet, navigator or smartphone.
