Thursday's report echoes a Wall Street Journal article last month that also pointed to struggles in the iPhone X's production, particularly the Romeo modules.
iPhone X features the new A11 Bionic chip with a special neural engine that helps power Face ID which unlocks the device by taking a 3D scan of the users face.
The production increase comes as suppliers are still facing issue with parts of the TrueDepth camera.
Once Apple gets a handle on production, analysts are anticipating that demand for the iPhone X will be off the charts.
Limited iPhone X Release Date Units?
As these dates near, it's only natural that Apple has begun to put up advertisements for the next-generation iPhone on billboards throughout the world in cities like Tokyo, San Francisco, Toronto, London, and more. This is seconded by Jeff Pu, an analyst with Taipei-based Yuanta Investment Consulting who agrees that the production issue is coming from the dot projector. However, the analyst has cut his forecast of 2017 iPhone X production by 10% to 36 million units.
Ever since the iPhone X was announced, it has consistently been reported that the handset will be in short supply for several months after it's released.
Apple will start taking pre-orders for the iPhone X on October 27 and will launch the device November 3. The iPhone X, like the iPhone 8 and 8 Plus, features wireless charging capabilities, is waterproof and supports augmented reality apps.
