Long-time Apple supplier Samsung Display will start its production of [iPhone 15](https://appleinsider.com/inside/iphone-15 "iPhone 15") OLED panels a month earlier than planned, reportedly due to issues at a different supplier.

In early March, Samsung Display was said to have [lost its exclusivity](https://appleinsider.com/articles/23/03/02/samsung-loses-exclusive-as-iphone-15-gets-multiple-screen-suppliers) to produce displays for the entire iPhone 15 range. It now seems that some of those orders are being returned back to the South Korean producer.
