Apple shares fell nearly seven per cent on Thursday and Friday over reports of a sharper slowdown in smartphone sales this year, Financial Times reported late on Friday.
Not just Apple, the news led to several global chipmakers losing market valus, including Analogue Devices, Dialog Semiconductor, Qualcomm and Qorvo.
For the first time since 2009, smartphone sales in China fell last year while global sales fell in the fourth quarter of 2017 for the first time since 2004.
In another setback for the iPhone maker, its efforts to get LG Display's OLED screens for future iPhone production line "have hit manufacturing issues", the Wall Street Journal reported on Friday.
Apple is reportedly divided on whether LG will be able to succeed as Samsung's replacement for OLED displays.
The LCD panels which are currently being used in the iPhone 8 and iPhone 8 Plus are supplied by LG. Apple Watch screen is made by LG Display.
There are reports that Apple is designing and producing its own device screens, secretly at a facility near its headquarters in California.
It is believed that Apple will switch to OLED displays for all of its iPhone releasing in 2019.
