Kirin 980 sets the direction for the industry

The production technology of mobile processors directly affects their performance and level of energy consumption. Today, the most common manufacturing process is 10 nm, and the Kirin 980 was the world’s first commercial chip manufactured using the latest 7 nm process developed by TSMC.

Improvements in processor production technology go in parallel with the consistent evolution of chip designs. Physically, a silicon semiconductor can be reduced to 7 nm before electrons begin to flow uncontrollably from one gate to another.

Huawei developers began basic research into the new 7nm process three years ago. To effectively solve all the problems of mass production, the industry’s best specialists in integrated circuits and system design were assembled. Featuring a heterogeneous converged system architecture and optimized CPU, GPU, NPU, ISP and DDR, Kirin 980 contains 6.9 billion transistors in an area of ​​less than 1 cm2. Powerful CPU, GPU, DDR, smart NPU, high-quality ISP and fast modem provide the processor with high energy efficiency.

To ensure smooth operation under various modes and usage conditions, the first 7nm Kirin 980 chipset went through a variety of tests aimed at verifying performance and power efficiency. A comprehensive check of all components provides the most reliable guarantees of stability and comfort for mobile device users.

Telephony (telephony)

This tab contains items related to the network and mobile communications. For example, you can test the modem, antenna, or select the optimal settings for the CFU. Usually nothing needs to be changed, since everything works correctly from the start.

To change parameters, you need to open the “BandMode” section, and then simply uncheck unused frequencies. Finding out what you need to leave is no more difficult — the official website of your telecom operator will help with this. And if you scroll down the list a little lower, you will see a sub-item designed for working with networks.

And in some, mostly remote corners of the globe, there may be no modern 4G or 5G mobile Internet standard at all. So why waste your smartphone’s resources trying to find a network that doesn’t exist? That’s right, there’s no need. We simply turn off unnecessary networks and see how much the device’s battery life has increased.

In fact, the average user does not need to enter this tab. In this section of the engineering menu there are no settings that can positively affect the performance of the smartphone. But accidentally changing the parameters of wireless modules incorrectly is quite possible.

As for Bluetooth, you can get information about the strength of the current signal, although this data will not be useful to anyone. Yes, there are special points here that can be changed. But you can’t do without special knowledge in the field of signal transmission. You can try to do everything at random, hoping for an improvement in network performance, but this is not the best option.

Entering the engineering menu on android (command and program)

If you can’t enter the menu

It is quite possible that you will try to enter all the above combinations, but will not get into the engineering menu. This happens on Android 6 and some other fairly recent versions of the operating system. Apparently, the engineering menu is locked, or some specific code is required to call it.

Nowadays, it is difficult to imagine a smartphone that does not have a camera installed. The shooting module has become an integral part of a mobile device, like Wi-Fi or a second SIM card slot. And of course, every user tries to take a good photo using a mobile camera.

Looking at the pictures posted on social networks or blogs, you will notice that even with a high-quality camera it is not always possible to take an equally high-quality photo. Sometimes the reason for this is the human factor — well, in principle, a person is not able to capture a beautiful shot — but most often the matter is that the user ignores or sets the camera settings incorrectly.

You can significantly improve the quality of photos and videos in three ways:

• Using your own camera settings;
• Through the engineering menu;
• Using a special application.

In our article we will give basic tips for improving your photos, and also tell you in detail how to set up the camera on Android.

Before you start setting up your camera, you should understand the basic rules for shooting with a smartphone. By following these recommendations, you will already be halfway to quality photography.

1. Keep the lens clean. Before shooting, wipe the lens with a soft cloth so that the image is not spoiled by smudges and dust particles that inevitably fall on the lens;
2. Consider the light. It is extremely important that the subject is well lit. If you are photographing a person or object in a room, do not place it in front of a window so that the photo does not end up with one solid white spot. We’ll talk about how to adjust the camera to the lighting below;
3. Don’t overuse zoom. Smartphone cameras are usually equipped with a digital enlarger, which greatly distorts the photo. If possible, it is better to come closer to the subject so as not to end up with a similar picture:

1. Use the flash only for its intended purpose. If photography takes place at dusk, sometimes you can’t do without a flash. In this case, set it to Auto mode. The smartphone itself will “figure out” when it needs to be used. During the day, it’s better to avoid flash altogether:

In order to achieve a good picture, the user needs to set the right combination of camera settings that match the shooting conditions.

Let’s look at the main camera menu items in order:

Exposition. This function determines the amount of light that hits the camera sensor. As a rule, the exposure varies from -3 to 3. If you are shooting in the evening, set the exposure to positive. On a bright sunny day, it is better to reduce the exposure.

Xiaomi engineering menu

Despite the fact that our test Redmi 2 runs on a Qualcomm Snapdragon 410 processor, it also has the functionality that interests us. To enter it, you need to tap on the “Kernel version” item several times in a row.

The menu consists of five items:

1. Automatic Test. Automatic test of all device parameters.
2. Single Item Test. Each of the 25 tests is taken separately. We will talk about this in detail below.
3. Test Report. Report on the completed texts and their results.
4. SW add HW version. Information about the smartphone version, IMEI and other numbers.
5. Device View. Smartphone hardware data.

Of course, the most interesting item is the Single Item Test, where you can take a huge number of tests.

Let’s immediately make a reservation that in the device we tested there was no way to configure anything — only a functionality test. At the end of each procedure, you need to note its status: successful (success) or not (failed).

• Key — functionality of physical buttons. Interestingly, it was not possible to complete it successfully, since when checking the power button, the smartphone turns off.
• Backlight — display brightness.

• TFlash. Testing a memory card with two results: either everything is fine, or the card is damaged.
• Bluetooth. Searches for available devices.
• SIM Card. Test for the presence of SIM cards.

• Vibration. The gadget vibrates — everything is ok.
• RTC (Real Time Clock) — operation of the built-in clock.
• Speaker. Testing the conversational speaker. We didn’t understand how to get through it. We will be grateful if you can tell us in the comments.
• Receiver. Translated as receiver, receiver, but music plays during testing.
• Headset. Testing the 3.5mm jack to detect headphones, play sounds, and support headset control buttons.

• Wi-Fi. Detection of nearby access points. There are no settings.

• Torch (flashlight): shines / does not shine.
• The loopback test includes a spoken microphone test. First, click Recording, then Playing.
• LCD. Screen colors.
• GPS. Detection of available satellites.
• Gyro (gyroscope). Three parameters — X, Y, Z — change depending on the position of the device in space.
• G-sensor (Accelerometer). Rotate the gadget in all planes and turn it over. The three parameters should be ok.
• Proximity Sensor. It is usually located near the speaker and is designed to dim the gadget screen during a conversation, thereby eliminating accidental clicks.
• Optical and Magnetic Sensor (optical and magnetic sensors) — points we don’t understand, share your knowledge in the comments.

After passing all tests, you can go to the Test Report section. As you can see, our “animal” is in excellent shape and has passed all the tests, which is very pleasing.

Intelligent features of the kirin 980 processor

The first processor equipped with artificial intelligence technologies, the Kirin 970, introduced in 2020, opened up the possibilities of local artificial intelligence for users. Today, Kirin 980 offers even more powerful and functional tools for processing applications using artificial intelligence technologies.

A list of settings that catches your eye when you first enter the secret menu. Here the developers have provided many important points:

Reliable connection and Internet speed up to 1.4 Gbps

As smartphone users spend more time in apps and games, and use a wide variety of services, from contactless payment for purchases to navigation and search on the Internet, their lives become increasingly dependent on the speed and stability of wireless communications. The new Kirin 980 processor has improved 4G communication functions.

Kirin 980 received support for the LTE Cat.21 standard. In addition to download speeds reaching up to 1.4 Gbps, it is able to flexibly use combinations of frequency bands from different telecom operators. This allows users to be guaranteed high data transfer speeds on any network around the world.

The developers of the Kirin processor took into account the requirements of real-time online applications, such as resource-intensive multiplayer games, which are highly dependent on the quality of communication with data networks. Engineers were able to achieve stable and smooth gameplay in the most difficult conditions — for example, on high-speed trains, in the subway, on highways and in crowded spaces.

The processor was tested by over 100 experienced gamers who tested devices for over 30,000 hours in 50 of the world’s largest cities, identifying potential issues with mobile networks. Based on the results of this testing, the Kirin 980 underwent additional optimization, which reduced the number of lags and freezes to ensure maximum comfort for mobile gaming fans around the world.

In addition, Kirin 980 was equipped with the world’s fastest mobile Wi-Fi chip Hi1103, supporting a frequency of 160 MHz. This combination has a theoretical peak download speed of 1.7 Gbps, which is 1.7 times faster than last year’s industry average.

Moreover, the Hi1103 chip supports the industry’s best ultra-precise dual-frequency L1 L5 GPS positioning. The L5 frequency range improves positioning accuracy by 10 times, allowing you to accurately determine your location in difficult urban environments and on high highways.

New phone settings

To learn and set up a new phone, the built-in “Tips” application will help, which is indicated by an icon with the English letter “i”. It will offer feature descriptions and links to manuals. After some time of using the smartphone, prompts are automatically turned on based on the owner’s use of the phone.

The pre-installed application allows you to quickly connect to any Huawei brand device to download or transfer files. Communication channels used: Bluetooth and Wi-Fi. When the application starts, the specified communication modules automatically switch to the active state.

How to transfer files to another Huawei device: – Select the files you want to send. – Click: Send. – Select the recipient device from the list of available devices and confirm sending.

I can’t enter the Android engineering menu: reasons

• Firstly, many smartphones or tablets with Qualcomm Snapdragon, Intel or Tegra processors either do not have a menu or are very difficult to access. In some cases, you don’t even have to try.
• secondly, custom firmware may be the cause of the problems. In a number of them, access to configuration tools is simply absent or blocked. For example, you will not find an engineering menu in the CyanogenMod firmware, which is very popular among users. The reason is simple — the firmware was originally developed for Snapdragon-based devices.
• thirdly, the source of the problems may be the manufacturer himself, who hid the engineering menu more reliably or decided to remove it altogether. This also includes various types of errors from which none of the devices are insured.

Actually, solutions to problems lie on the surface. If the smartphone is powered by Snapdragon, Intel or Tegra, then in most cases nothing can be done. However, even on these devices you can access a number of hidden settings, which we will discuss below.

By the way, on Xiaomi smartphones, which are mostly based on chips from Qualcomm, you can access the engineering by clicking several times on “Kernel version” in the smartphone settings (section “About phone”). Finally, in some cases, flashing your Android device to stock (official) firmware will help.

The second way to open access to the engineering menu is through applications. There are quite a few of them, you can download them for free from, but almost all of them are designed for smartphones based on the MediaTek processor. The MTK Engineering Mode application has proven itself quite well.

Again, it’s not a fact that each of the programs will work smoothly on your device — there are a hundred reasons why they will refuse to function. These tools are developed by small companies, so you’ll probably have to try a few.

People’s reviews

Do owners of Honor and Huawei smartphones use engineering mode in everyday life? Let’s find out from their reviews:

1. Anton. I have Huawei P20. After six months of use, the sound began to disappear. I answer people, I hear them worse and worse. Cleaned the speaker. Did not help. Thanks to access to the engineering mode, I was able to correct the situation completely on my own, without resorting to the help of paid specialists.
2. Regina. A friend of mine gave me a Huawei Y5 II. I like the phone, but I wasn’t initially happy with the camera. I gave it to a friend. Using this menu, he was able to reconfigure it so that I started to like everything. So this is a very useful feature.
3. Vladimir. I tried to access this menu from my Honor 7A Pro. But I couldn’t, unfortunately. Well, okay, I’m guaranteed not to mess it up there!
4. Igor. I learned about this opportunity a long time ago. Naturally, I also found out the access code for my Honor 9 lite. I’m entering. Don `t come in. I tried it five times. But now I’ve learned that you can’t copy — you just have to enter it manually. I tried it now. It turns out that everything works great. Thanks for the info!
5. Oleg. I don’t know why, but on my Huawei Y3 only Project Menu launches. Maybe I’m using the wrong passwords? I seem to be entering it carefully. Or some special version of my gadget.
6. Marina. I have a simple Honor 10 lite. But I really like the smartphone. For me personally, this is the ideal phone, with the right settings. That’s why I didn’t even try to change anything about it. I know that I will only make everything worse.
7. Yaroslav. It runs on Honor 8X without any problems. The engineering menu really provides a lot of information and opportunities. True, I’m still studying everything carefully. Then I will experiment. In fact, it can be adjusted so that even no additional firmware is needed.

It is important to understand that the engineering menu was not initially intended for active use by ordinary people. Therefore, if you decide to take advantage of its capabilities, you should think in advance about the likely consequences of the changes made, and also clearly understand the purpose of this or that action.

Huawei service codes (also called engineering codes) make it possible to check the device for errors, malfunctions and general performance. In addition, they allow you to obtain information about your smartphone that may be needed to configure or update the software.
