Samsung aren’t going to deny their biggest customer. It took Apple so long to introduce OLED phones because they had issues early on and weren’t up to quality. I’m not sure where Huawei got their screens, but they either found another supplier or bought them from Samsung. It would surprise me if they would be willing to sell screens to Huawei, their biggest competitor, but not to Apple. Again, Samsung is in no position to deny their largest customer. In the end, the tech just isn’t ready for prime time, as shown by these devices.
