According to the Journal, the new $1,000 iPhone, set for to be revealed on Tuesday, could suffer shipping delays due to complications with a new type of screen, which was difficult to install with Apple's fingerprint sensors for the Touch ID feature.
The report comes after several Wall Street analysts have predicted delays for the iPhones, including top Apple analyst Ming-Chi Kuo, who reportedly predicted the manufacturing difficulties in research notes for KGI Securities.
At least one of Apple's new phones is expected to have an organic light-emitting diode (OLED) display, the technology that allows phones like the Samsung Galaxy Edge to have curved screens. Only a few companies, including Samsung, have capabilities to manufacture large quantities of phone-sized OLED screens.
Shares of Apple dipped to around $161, down a hair from the day's high of $162.24. Shares of Foxconn Technology, an Apple supplier, also fell in the afternoon.
Apple declined to comment to CNBC.
