How to enter the engineering menu of Huawei and Honor smartphones: codes, how to increase the volume?

Many of us have long fallen in love with smartphones based on the Android operating system. They have always captivated us with their unpretentiousness, good reliability, as well as convenience and ease of use. The same can be said, in particular, about smartphones from the well-known company Huawei, which are also based on this operating system. The company from the Middle Kingdom always keeps up with the times and equips its phones with the latest versions of the operating system and multifunctional firmware, trying to keep up with the generally recognized leaders in the Android smartphone market.

However, few of us know that already quite convenient Huawei phones can be made even better by fine-tuning them to suit your needs. What we can configure in the phone’s main menu is only the tip of a huge iceberg; the rest is hidden from users in order to avoid device failure. However, people who deal with mobile phones not just at the user level, but, for example, work in a service, can easily access advanced settings on almost any phone using the engineering menu.

Looking ahead a little, it’s worth saying that inexperienced users really shouldn’t go into this “forbidden forest”, so as not to simply ruin their device through carelessness. But if you are confident in yourself and think that you understand technology at a sufficient level, then the Huawei engineering menu is exactly what you need to fine-tune your device as much as possible.

What is an engineering menu and what is it for?

The engineering menu for Huawei and Honor is a program built into Android. But keep in mind that some developers deliberately delete the program after all checks. After this action, it will be difficult for the user to customize the application for themselves. Therefore, some people download a separate program with similar actions or use firmware developed by developers of other equipment manufacturing companies. But keep in mind that using unverified sources can harm your device. The consequences of such actions may not be resolved by the company from which the smartphone or tablet was purchased.

It is noteworthy that the option on Huawei phones and tablets is always located in a specific category and is not removed by the manufacturer. Therefore, if you didn’t open it right away, you just need to perform the steps again. Keep in mind that incorrect installation will not improve the performance of your Android-based gadget (smartphone or Mediapad tablet), but rather will aggravate the problems. If such breakdowns occur, the client is solely responsible. It will not be possible to make a warranty claim.

It is noteworthy that the function is not in a prominent place. You need to know exactly how to connect it. This is done to prevent an inexperienced user from messing up the settings. Also, this option is not needed for permanent use. It is enough to set the parameters once and use their results.

Wireless equipment

The item contains information about all equipment that uses wireless transmission technology. It is possible to adjust its operation and conduct a readiness test.

Paragraph	Meaning

The code will work after entering. But some smartphones require confirmation of the action by pressing the call button. There is no point in saving it to Contacts, since it only works after manual entry.

How to turn it on

After the instructions discussed above, the logical question arises of how to enable the proximity sensor on Honor 10 and other devices. After purchasing a smartphone, the option is already enabled and does not require additional configuration. If you decide to disconnect the device and did it earlier, use the instructions discussed above. The difference is that you need to finally move the knob to the Enabled position (if you deactivated the option through the settings) or remove the check mark next to Turn off in proximity when using the Sanity application.

Codes for accessing the Huawei and Honor engineering menu

Do not panic at the first failure, since most devices easily respond to codes. They partially perform functions that are usually available after entering Engineering Mode. Correct input of characters is a guarantee of a successful process.

Service codes have been used by developers for a long time. Widely used before the advent of smartphones. But operating them is not as comfortable as simply activating a certain function in Engineering Mode. Entering an unverified code can also harm the operating system of the gadget.

The most commonly used service codes:

• *#06# — IMEI address is displayed;
• *#*#4636#*#* — checking data about the gadget, charge, rational use of energy;
• *#*#7780#*#* — return to factory settings.
• *2767*3855# — formatting.
• *#*#34971539#*#* — informing about the camera status.
• *#*#7594#*#* — making changes to “Enable”/“Disable”.
• *#*#273283*255*663282*#*# - copying files, used to save the most valuable ones.

There are other codes that allow you to configure your phone and use each function for its intended purpose for simplified operation of the smartphone.

How to increase the volume through the engineering menu of Huawei and Honor

Sound interference is a common problem. The inability to solve it after activating standard criteria motivates us to evaluate the advantages of a special option. Dial *#*#2846579#* (required manually).

Determine the volume change setting option.

1. The sound produced in the built-in speaker.
2. Sound expressed through headphones.

To activate the first option, click on “Type” / “Media” / “Level” / “Level 0”.

The second method involves activating “Value”/“Max. Vol."

Why doesn't the proximity sensor work?

The main visible problem is that the display is activated without your authority while it is in your pocket or other place. That is, the screen remains active and does not go dark during a conversation, which is why accidental clicks are possible.

The main reasons that may affect the operation of the presented technology:

• The system automatically disabled the option due to a malfunction in the system.
• Operating system malfunction.
• Damage to the sensor itself or contamination.
• Unsuitable safety glass.

Alternative – Project Menu

Not many developers want to remove the engineering menu. But if the developers decide to do this in a particular gadget, they offer an alternative - Project Menu.

This program differs in that it only informs you what and how to do, as well as the following data:

• battery charge, rate of discharge;
• SIM card, country and smartphone developer company;
• information about the OS and other installed applications.

The owner can record how quickly the phone has drained since it was last charged and see what applications it has used. And thus determine the programs that are the most energy-consuming. This option is suitable for those who do not have the opportunity to get into the engineering menu. Similar, but somewhat shorter. You won't be able to run testing with it. It's better to use codes.

You can enter Engineering Mode from Honor 4c/7a/7c/7x/8a/9 Lite/10/10 Lite/20 Pro and Huawei Y5/P10 Lite/P 20 Lite/P 30 Pro/P Smart 2019/Nova 2/ phones. Nova 3/Y6 Prime/Y7. Almost all owners of the listed gadgets have heard about this function. But not many dared to test the benefits by their own example. It is noteworthy that Android is a system that is intuitively understandable even to those who have previously used a push-button device for communication. A person who has previously used gadgets exclusively from Apple will not find anything difficult in it. But the options can be simplified even further thanks to the Engineering Mode. But all settings must be carried out very carefully so as not to harm the gadget.

The review describes only the basic features, but you can use it to change the font, optimize energy saving, and learn in advance about possible breakdowns and methods for their further development. And also, if necessary, resuscitate the device. Often used by professional repairmen.

The proximity sensor on Android stopped working

If the proximity sensor of honor and Huawei does not work? Try calibrating it using the application installed on your Huawei phone:

The screen calibration procedure itself is divided into 4 stages. What you will need to do:

1. Performance. Move your hand where the sensor itself is located. A color change from red to green indicates normal operation. On most Android devices it is located on top near the speaker. Click “Next”. It is represented by an arrow at the bottom right of the screen.
2. Stage two is to turn it on. Without touching the sensor itself at a distance of about 1-3 centimeters, move your palm until the color of the indicator changes from red to green.
3. Stage three - disable. To do this, remove your palm from the proximity scanner. The indicator should change from green to red.
4. Saving settings. The checkmark at the bottom means “Save”, so you need to click on it so as not to repeat these steps again.

After these steps, reboot your phone, otherwise the settings will not take effect. When the system boots, you will see a new “Proximity Sensor Reset” icon on your desktop. It's better not to delete this application. The presented calibration may be useful to you in the future. No one is immune from repeated failure.

The developers strongly recommend performing this operation several times if the problem reoccurs when the proximity sensor stops working. To do this, open the installed “Proximity Sensor Reset” program and repeat the steps described above.
