i believe Huawei was in hurry to leaked M60 for US commerce secretary. it could be risky for SK Hynix coz of US sanctions.did you forget about the YMTC SSD on iphone that freaked out the DC crowd?
In this case, I'm surprised Huawei is not using YMTC SSDs
maybe proper production will use domestic flash memory. its not about technology. if Apple can choose YMTC then why not Huawei.
