According a report in Business Korea, some components for the current topline iPhone model are "estimated to reach zero in the second half of this year." The phone's OLED screens, notably, are sourced from Samsung Display, a division of Apple's archrival in the smartphone sphere.

That reinforces earlier supply chain reports from analyst Ming Chi Kuo that the iPhone X will be discontinued once a successor model or models -- rumored to include larger-screen LCD versions -- hit in 2018. That's in contrast to Apple's standard retail strategy, which is to leave the earlier iPhone model on sale at a reduced price.
