First, to answer the first question, the domestic phone in the end there are those parts from abroad (a short period of time can not be replaced by the domestic core components)
That is, we usually say that the processor, but this is not purely what we think of as the CPU but a collection of chips which integrates the CPU, GPU (graphics), NPU (AI chip), baseband chip, ISP image processing chip, etc.
This is the first time that we have seen the processor in the domestic cell phone. Chip, ISP image processing chip, etc. A collection of the world's current ability to be used for commercial processor chips only Qualcomm Snapdragon, Apple A series, Huawei Kirin series, MediaTek, and Samsung Exynos series. In addition to Huawei, all of our domestic cell phones are equipped with Qualcomm Snapdragon chips (a few equipped with MediaTek and Samsung) and there is no way to be replaced by domestic chip companies in a short period of time.
That is, we often hear the Sony IMX series, such as the recent fire of the IMX586 4800W pixel sensor module, he is a cell phone camera system inside the core components, the current domestic cell phone is commonly used by Sony and Samsung, even Huawei is the use of and Sony jointly developed CMOS sensor module. And the domestic market is basically a blank.
A very inconspicuous little thing, but at present, the domestic cell phone memory is still all from abroad, the provider of Samsung-based, and our domestic (not to mention TW) at present, there is no alternative resources.
At present, although the domestic screen has made great strides in the development of the representative of BOE and Tianma, but the overall performance and yield still can not meet the current domestic cell phone market, so most of the current domestic cell phone screen in the field of high-end still come from Samsung, LG and other one-vote foreign manufacturers, more than the Samsung AMOLED screen, and low-end cell phone using the LCD screen is currently already Basic realization of domestic production. The screen above the scratch-resistant glass cover plate is also from the U.S. Corning Incorporated, which is often referred to as the Corning Gorilla series, the domestic glass panel manufacturers, but its performance can not compete with it.
Let's talk about the second question, about Huawei Kirin series SOC in the end is not the national production
Huawei's Haisi Kirin theoretically can be counted as a domestic chip, although the use of ARM provides the architecture, but in the power management, baseband chip, NPU chip and other aspects of the realization of the domestic, is the highest degree of domestic cell phone chip one. But to be clear, although the use of ARM architecture and solutions, but Huawei's Kirin processor and Qualcomm / Samsung / Apple's chip is still a gap; Huawei is a direct application of the core architecture provided by ARM to do the package processing, such as the familiar Kirin 980 is directly using the core architecture of the A76, the GPU is a direct application of the public version of the public version of the Mali architecture. The GPU is directly applied to the public version of the Mali public version of the architecture. The Qualcomm Snapdragon we know is the ARM core architecture for the magic version, Apple A series is even in the underlying instruction set level adjustment, and then encapsulated into its own core architecture. This is also a gap between Huawei and other chip giants at present. But according to current information, Huawei has obtained the instruction set level authorization from ARM, and I believe that in the near future, Huawei can also create its own core chip architecture.
Overall, our domestic cell phones are still very dependent on foreign core components, so the road is long, and walk and cherish ah. I hope that our domestic phone can also go better and better, as soon as possible to create a completely intellectual property rights of the domestic phone to.
I'm going to take Huawei as an example here, because the questioner mentioned it! However, due to the large number of cell phone models, I will take the Huawei P30 as an example here, which is also the latest model. In addition, there also happens to be a list of suppliers of Huawei P30 at the previous stage, let's take a look to know roughly which parts are foreign.
P30 suppliers roughly list, in order to have a clear comparison, so domestic and foreign suppliers I listed:

Summary: the above 15 domestic suppliers, but BOE is not counted, if the P30 is used BOE screen, then you can add another one; 18 foreign suppliers, mainly U.S. companies, followed by European companies, and finally Japan and South Korea.
As for the Huawei Kirin chip is based on the ARM architecture, design and development are all Huawei's own, but does not mean that this chip is foreign, a chip is not enough to have the architecture, and not who bought this architecture can develop their own chip, this piece of technical barriers are still relatively high. However, Huawei has gone on the road of self-research architecture, there is news that the Kirin 990 is the use of independently developed new architecture, and AI chips are also based on self-research Da Vinci architecture.
Well, as you can see from the above, in today's globally integrated world, there is no one who can independently manufacture a cell phone, and all need to provide more specialized accessories from various suppliers. Therefore, in the field of cell phones, the integration of suppliers is also quite an important work, without effective integration, you can not make a good product. Finally, for the core of the chip, Huawei has taken the way of self-research, which is the most correct path, surrounded by other professional accessories manufacturers supply is good.
Thank you for reading, give a point of praise to encourage it, welcome to pay attention to the Rochester Bug Society, thank you ~ ~
In addition to the "patriotic function" is domestic, the other all imported!
Some of the parts in the domestic cell phones are sourced from abroad, in fact, this is the normal performance, but also represents the global integration of the economy, the economy of each country. Technology, products, etc., you have me, I have you, is the ultimate result of economic market regulation.
Now talk about what are the more important parts in the domestic cell phone is originated from abroad.
1. CPU
Even Huawei only uses its own Kirin chip in most of its own high-end machines, and the patented technology in the Kirin chip is owned by Huawei itself, by domestic companies, and by foreign companies.
Some of Huawei's low-end and mid-range ones use Qualcomm's 600 or 700 series chips, partly due to Huawei's own production capacity, but also due to strategic factors.
From the chip supply point of view, the chip design and architecture provider is mainly ARM, this big brother does not say two brothers, are the same;
CPU chip vendors are mainly Intel, MediaTek, Meiman Electronics and so on.
2. camera
Once the camera, we are all familiar with the manufacturers is probably Sony, Samsung, and so on. At first glance, all foreign, but in fact, the current domestic camera module for the three heads of the Ophiophoton, Sunny, Qiu Titanium Technology.
Sunny and Ophiuchi ranked first and second, but its supply is to go to the low-end market, high-end or Sony, LG, Samsung and so on.
3. Storage
For now, this stuff seems to be mostly Samsung home. However, domestic chips are also working hard, such as the Yangtze River NAND.
4. Radio Frequency Part
Radio Frequency (RF) is the abbreviation of Radio Frequency, simply put, RF is the part of the phone related to communication with everyone.
Huawei RF connector suppliers are mainly RF antenna suppliers Haoxun, Qorvo, Rosenberg;
Connector suppliers are mainly Amphenol, Hirose and Zhongli Electronics.
5. Screen part
Although BOE and SZTEMA supply strength is still considered to be strong, but due to the quality and defective rate of the relationship between only a part of the market.
Well, it probably means that at present there is still a large part of the screen set in Samsung, Corning, LG and other big manufacturers.
Additionally, there are more cell phone parts to go, in the cost and technical factors to consider, who is the right price, cost-effective, or irreplaceable with who has no problem.
We can see that domestic manufacturers are trying to catch up with the international level, recognize the gap and catch up. In the long run, there is still a lot of potential and room for development of domestic cell phones, little by little to catch up with it!
Many domestic research and innovation companies are also working hard to make China's manufacturing better and better!
Those who took the boycott of foreign goods as patriotism a while ago have read it well. Patriotism does not necessarily have to boycott foreign goods, but you have to have the ability to turn these 囯货into domestic goods, then you are patriotic, light boycott has no use. Boycott foreign goods people buy foreign goods people all as traitors, to put it bluntly, casually to your home a flip, you are all traitors, because now these high-end equipment are all combined, who can not be separated from who.
Including Huawei cell phone all domestic phones seventy percent of parts are foreign ...... This is not an exaggeration
The key problem is that people's use of foreign low-grade, domestic is the key to rely on others. Recognize it or not, it is true that others provide the opportunity to succeed
A Huawei cell phone more than 2,000 parts and components of Japan accounted for 88% of the total, while the cost of only 31%, which explains what the problem is? Capacitor inductance of these small parts can only be counted as a "big piece" is the Sony sensor, these are alternative programs, the rest of the cost of the chip screen and so on accounted for the majority of the cost, the topic involved here is the core technology, Huawei small to power management chip to soc and 5g chip can almost all do self-sufficient, these cell phone The core component technology Huawei is firmly in their own hands, these years vigorously support the BOE LCD panel is basically not subject to the constraints of Samsung LG, while other domestic manufacturers left the Qualcomm family bucket is difficult to move!
cpu this piece of Huawei Qualcomm Apple MediaTek are ARM license, which is like a building materials we all use, but to repair the house into what depends on the skills of each family, so do out of the soc performance is not the same, as for the OEM currently only Samsung can produce their own processors other need third-party OEM, cpu OEM enterprise TSMC is the strongest technical strength, so those to Huawei with the processor is not the same, but the company has been the most powerful, and the company has been the most powerful, so those to Huawei with the processor is the most powerful, so the company has been the most powerful.
In addition to the shell are foreign
It is impossible to domestic ah, accessories only abroad. Huawei design CPU. CPU even if Intel even do one will not do all down themselves. The lab can make it, and mass production can't be done by a single company.
Don't worry about domestic non-domestic Huawei U.S. core and how so, buy over the patent is their own, Huawei production ......
