The acquisition of a new smartphone or tablet is a real celebration for many. Each owner expects that the gadget will be pleased for many years with its reliable operation and the absence of any problems. Moreover, regardless of who the collector is, and what control system is installed.
However, as it 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 my understanding. One of the available tools is the Android engineering menu.
Secret Settings Everybody Knows About
At the final stage of configuring the software component of the gadget running the Google system, the 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 thoughtless use of this tool can lead to unpredictable results, access to it is most often hidden from users. However, in fact, the secret is already known to everyone - in order to learn how to call up the mentioned menu, it is enough to take only a few minutes to find recommendations.
A few important points
However, not all mobile devices can be entered into the Android engineering menu. In order to take advantage of its capabilities, you need to make sure that the gadget meets certain requirements.
Firstly, the central processor must be necessarily produced by MediaTek (or MTK). On inexpensive Spreadtrum models, for example, SC-6825, popular Qualcomm Snapdragon, various Tegra NVidia and Intel, trying to launch the Android engineering menu is useless. It is not there. Performance cannot be achieved, even if prudently installing the appropriate application.
Secondly, various modified operating systems, for example, the popular CyanogenMod in some circles, do not allow you to run the configuration program, as 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 is original or created on a basic basis.
Thirdly, the application itself (file) must be present among the programs, even being hidden from the standard explorer. So, some manufacturers of mobile devices after completing the settings of the software part simply delete the engineering menu "Android". 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 cannot be said which one is better, since a direct comparison is incorrect. Therefore, we will consider them one at a time.
One of the most “ancient” options, which was used in the first models of smartphones and tablets, is that the user in the dialer (the so-called dialer) does not dial the subscriber’s number, but the special Android engineering menu code, similar to checking funds in the account. If the combination is recognized and accepted, the setup application starts. Some mobile device builders use their own modified code, so the standard set does not always work. Otherwise, to invoke the menu, type the following character order without spaces - * # * # 36 46 633 # * # *. So simple.
The usual way to access
Using a secret combination is not always convenient, if only because the sequence of 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 sequence of signs. One of the most famous applications is the so-called "Mobile Uncle", or MobileUncle Tools. It is free, so there are usually no problems finding and installing. At the time of writing, the current version is official 2.9.9 or assembly 3.1.4, which has additional support for some new processors.
In order for the program to work, the user must first obtain 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 starting the application, you should select the third item called Engineer Mode (both in Russian and in English versions), and in the window that opens - "Work with MTK". If you are prompted for root access, you must answer in the affirmative.
How to regain access to the mode for engineers
If the manufacturer of the mobile gadget has taken care of the security of the operating system by prudently deleting the configuration program, then it can be reinstalled. To do this, find the installer on the Web that repairs EngineerMode.apk and install it.
We do not indicate the exact name due to the abundance of analog clones. For example, one of them is called “Engineering Mode”. You can also simply copy the missing file to the system folder located on the system \ app path. After that, you can use any method for access: either dialing a number or directly calling from the program interface. Note that for these operations, root rights are required .
Features of the miracle program
Setting up "Android" through the engineering menu, despite the ambiguous attitude of the gadget owners to this, makes it possible to solve several important problems. In particular, to adjust the sensitivity of the microphone, cure the "childhood illness", manifested in the insufficient volume of the system speaker, reduce battery power consumption by turning off scanning of the "extra" ranges, and reduce the time of satellite search by the receiver of the global positioning system. Let us dwell on the above functions in more detail, since it is they that are most in demand.
Ringer volume
Raising the ringer volume is easy. To do this, select the “Audio” section with a swipe to the right. A list of modes appears. For the system speaker is responsible LoudSpeaker Mode, subsection Ring. The parameter in the first window should not be changed, but in the second you can register a higher value. Developers can initially set the indicator to 130, which is quite quiet, but 156 is already close to the limit. The maximum is 160. After editing, you need to click the Set button, located here, and reboot the device by correctly exiting the program.
Mobile carrier frequencies
To optimize the energy consumption of a mobile communication device, you can turn off scanning of "extra" frequencies. In our country, when working in ordinary 2G / 3G networks, the standard 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, proceed to the Location Based Service and open the EPO. Here you need to make sure that the checkboxes are checked for Enabled and Download (if they are present). After that, you should return to YGPS and in the information section alternately click “Full”, “Cold”, “Restart”. Next, you need to select the “Satellites” item and wait until the answer is fixed (green dots on the map). Everything takes 2 to 5 minutes. After that, it remains to exit the menu, close the program and restart the gadget.
To summarize
The engineering menu of devices running the Android operating system opens up opportunities for the gadget owner, 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 for those who are already completely satisfied with the work of a tablet, navigator or smartphone.
