Not every person who has their own mobile phone, thoroughly versed in the various features of the operation of the device and the intricacies of its settings. In particular, many do not know how to enter the phone’s engineering menu and why do they need to do it. In fact, the engineering menu often becomes one of the main tools of specialists of various service centers, which eliminate all kinds of firmware errors or any malfunctions in the device’s internal program.
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 the number * # * # 3646633 # * # * and pressing the Audio button or simply by using the specialized MTK Recovery utility.
Audio
There are several categories in this section:
- Set Mode - select a profile.
- Normal Mode - a standard profile.
- Headset Mode - a mode for using a special headset.
- LoudSpeaker Mode - a mode in which the speaker in the phone is activated.
- Speech Enhancement - a mode in which a fully automatic correction of speech signals is carried out.
Before choosing any maximum possible values, you should make sure in advance that this will not make you encounter any sound problems. In the predominant majority of cases, it is highly discouraged to do this for the reason that the maximum settings can provoke the appearance of a rattling effect and a whole host of other interference, 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 imperative to record those that were installed by default, so that in case of any problems you can quickly return them to their 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 - must be left and do not touch, and then go below to the following characteristics.
Initially, you should configure the general modulation of the Tone volume, for which, in the corresponding Value section, you will need to set the optimal volume value 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 maximum possible volume. But, as mentioned above, it is highly discouraged to set the value to zero, as the speakers will begin to produce a wide variety of side effects, such as rattling sound and much more.
Now go to the Type Side tone menu, but here it is initially not recommended to touch anything, as it may happen that during the conversation you will hear only yourself, but not the interlocutor. Or try changing the values at your own peril and risk in different ways. The following characteristics are most suitable:
- Audio - 1.
- Speech - 1.
- FM - 1.
- Mikrophone - 1.
- Key-tone - 70.
If it seemed to you that the music or the radio is playing too quietly in the headphones, then in this case you can slightly adjust the profile for the headset, but do not forget to restart the phone after that so that the settings are saved.
How to change the volume of negotiations?
The conversation volume through the engineering menu changes as follows:
- Go to the menu.
- Choose Audio.
- We find the Speech enhancement characteristic, which is responsible for how well we hear the subscriber on the other side.
- Click on the Common Parameter button, and then select Normal Mode.
- Now we look at the parameter Parameter (0), after which we set Parameter - 6.
- We start editing this parameter and change it from the standard 400 to 1, after which we press the Set key.
- Now audibility will become even more than acceptable, and in some cases you even have to lower the volume (often this effect is provided by the Samsung engineering menu).
Headphone Volume
By setting the following characteristics, you can adjust the volume of the 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 volume when listening to any materials. In particular, this allows you to make both the engineering menu of Samsung modern models and the menu of most other phones.
Service menu
The service menu also has several main points that may interest users:
1. BatteryLog . The engineering menu of FLY and other modern phones allows you to get extremely accurate information about the state of the battery, including temperature, voltage and other subtle parameters.
2. TouchScreen . A fairly wide parameter, which has the engineering menu of FLY and other manufacturers who produce modern touch phones. There are several submenus in this section:
- Handwriting . A fairly simple option is to draw with your finger on the screen, which allows you to check how well the sensors respond to touching them.
- PointVerification . It allows you to diagnose the screen calibration, and when you press the corresponding button, it shows if there are any errors and, if so, how much they are deviated from the desired value.
- LineVerification . Almost the same as the previous paragraph, only here from one point to another lines are drawn.
- ShakingVerification . Shake check.
3. Camera . The Android engineering menu in the Camera section includes several submenus that allow you to test or change various camera features:
- AF EM. Selects a test for a camera with autofocus.
- Raw Capture Launches the same procedure for testing a mobile device.
- Start Preview. Allows you to view the camera image on the screen.
4. Wi-fi. The submenus of this paragraph are as follows:
- Tx . Tx register tests.
- Rx . Rx register tests.
- EEPROM . Specialized adapter firmware, which also allows you to enable or disable its functions through addresses. If you use the Android engineering menu, it is strongly recommended not to change any parameters in these characteristics. After such an intervention, it will not be easy for qualified specialists to restore them, even if you try to make a backup “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 . Almost any 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 device models. Includes several submenus:
- TX Only test. You need to specify a value, then press [menu] and Done. Next, testing the Bluetooth Tx registers starts.
- Test mode Allows you to activate the test mode.
- NetworkInfo Details regarding RR. In this case, you need to select with a tick which parameters you are interested in, then press the Menu button, select the Check Information item and view the data.
- AutoAnswer This function provides the ability to automatically pick up the handset with an incoming call through the engineering menu. Settings are often missing and you can only turn this feature on or off.
- YGPS. Testing, as well as providing the user with information 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 options for solving the problem.
Initially, you need to go into Audio, and then select one of the following menus: Headset Mode, Normal Mode or Speech Enhancement.
Go to Normal Mode, after which in the Type list we look for the Value section. All values here should be set in the range from 0 to 255, while the lower the value you set, the higher the sound volume.
additional characteristics
In the Type section, you can also change other characteristics that interest you, from the speaker volume during negotiations (Speech) to the volume of keystrokes (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. Exactly 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 cannot provide you initially, then in this case, values from 1 to 5, but not 0, will be optimal for you.
Immediately it is worth noting the fact that here are not specific volume values, but only the principle is described. The specific values will already directly depend on the characteristics of your speaker and microphone, because, for example, those settings provided by the Explay engineering menu can bring the parameters an order of magnitude higher than the capabilities of your phone, as a result of which, trying to match these parameters, it can simply break. Keep this in mind and try to choose real characteristics that can satisfy your needs.
How to check?
In most phones, the engineering menu provides a specialized Ring Tone item that can be used to listen to any standard melodies directly from the engineering menu in order to determine how much we have changed the volume. Of course, it’s best to call someone and “live” to check the installed settings after completing all the settings, but if you are trying to do everything quickly and do not want to spend a lot of time, this function is most optimal for you.
Increase the volume of negotiations
Setting through the engineering menu the volume of negotiations is carried out in the above service menu. You can enter it as follows:
- Dial * # * # 3646633 # * # *.
- Install the specialized Mobileuncle Tools program on your phone. The first menu in this program is the entrance to the engineering menu of the phones. Using the program is much more optimal than performing all the actions manually, since there is no need to type a large number of numbers. After all, only values that will be optimal sometimes have to be selected within a few hours.
After that, you can dial various numbers and check how well you can hear your interlocutor and yourself.
Explay Features
A separate feature of the Explay engineering menu is the Battary parameter, which is responsible for battery levels. This characteristic determines the battery charge level and tells the phone when to turn off the power during charging. Thus, you can slightly increase the battery life of the phone, 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 the new type of phones has a function when you cannot call other subscribers when the battery is low. It is in this situation that knowledge about how to enter the phone’s engineering menu to change the battery’s characteristics can come in handy, which will allow you to spend more time on outgoing calls.
