Huawei is a big Chinese phone company that wants to make its own parts instead of buying them from other countries. This is important because China wants to be more independent and not depend on other countries for technology. The US government does not like this, so they are trying to stop Huawei by not allowing some American companies to sell parts to them. But Huawei still makes new phones with many parts made in China. Read from source...

1. The title is misleading and sensationalist, as it implies that Huawei is bragging about its tech self-sufficiency with the latest smartphone built with more homemade parts, but does not provide any evidence or quotes from Huawei itself to support this claim.
2. The article uses terms like "US-sanctioned" and "bypassing US sanctions" without explaining what these mean or how they affect Huawei's business or operations, making it unclear for the reader why these are important issues.
3. The article relies on a teardown analysis of the Pura 70 series to show that it has more homemade parts than previous models, but does not provide any context or comparison with other smartphones in the market, such as those from Samsung, Apple, or Xiaomi, making it difficult to judge whether Huawei's self-sufficiency is indeed remarkable or not.
4. The article repeatedly mentions China's progress towards technology self-sufficiency and the U.S.-China trade tensions, but does not provide any sources or data to back up these claims, making it seem like the author has a biased agenda against the U.S. and in favor of China.
5. The article cites an unnamed "source" who says that everything inside a smartphone is made by Chinese manufacturers, which is a gross generalization and ignores the fact that many components are sourced from other countries as well, such as South Korea, Japan, Taiwan, etc.
6. The article uses emotional language and phrases like "all about self-sufficiency" and "stepped it up a notch", which imply that Huawei's actions are driven by some sort of patriotic or defiant motivation, rather than by business strategy or customer demand, making it seem like the author is trying to influence the reader's emotions rather than inform them.
