Yes, Samsung refused to provide TFT-LCD to Huawei, but that happened 2yrs ago on Ascend using the first generation Huawei Hisilicon Q-core CPU, not Kirin. Nowadays the situation has changed a lot. China has at least 3 major manufacturers including BOE, producing LCD/AMOLED for TV, smartphone, and tablet, occupying around 1/4 global market share if i am not wrong, next to S. korea and Taiwan, and will replace Taiwan's position in 2yrs on market share. BOE is pretty active on R&D on AMOLED and other display tech reflected by their huge patent filings recently.

Yeah exactly. Everytime I say that, economic sanction -might be from one country to another or one company to another- is only a temporary punishment. Sooner or later the company or country will go on without the technology or product needed. I mean everytime a solution will be found. A similar example is US not selling weapons to China after the Tiananmen events. At first China had problems with it's defence, but today it has a vast military industrial complex. Of course Chinese won't sit and wait for Samsung to sell them the needed panels.
BTW, I think camera is also largely outsourced, Chinese vendors are also very aggressive these days.
I was refering to design on this one not the manufacturing. I guess many reputable brands today designs their own cameras and outsource the production.
