The United States only restricted Huawei's high-end chips, such as 5G chips, and did not restrict Huawei's low-end chips. Therefore, Huawei's mobile phone chip sources are divided into 2 large pieces, one is the Kirin 9000 chip that seems to be used up forever, but it is estimated that it is really running out.
One is the 4G chip that Qualcomm supplies to it, and at present, whether it is a flagship mobile phone or an ordinary mobile phone released by Huawei, Qualcomm chips are used
The original use of Huawei's own Kirin core chip, produced by TSMC. Now it uses Qualcomm 4g core chips
In addition to the inventory, the US company has begun to supply 4g chips to Huawei.
