I think many people wondered why Apple decided to release the iPhone XR later than other flagships. There seems to be an explanation for this.
The company split orders for smartphones between Foxconn (50-60%) and Pegatron (30%).
It turns out, according to Economic Daily News, Pegatron lost up to half of its initial orders for the iPhone XR, losing to Foxconn. And all due to the fact that there was a shortage of vital components, as well as workers in factories in China.
In addition to this, the supply of LCD screens from Japan Display (JDI) for the production of iPhone XR was not sustainable . Pegatron and Foxconn declined to comment. [Macrumors]
