Nikkei Asian Review:

A tech executive familiar with iPhone X production told Nikkei Asian Review on Thursday that manufacturers are still struggling to perfect 3-D sensors and in particular dot projectors in Apple premium handset’s TrueDepth camera system, though the person could not pinpoint exactly the problem.

And:

The executive’s comments were confirmed by Jeff Pu, an analyst with Taipei-based Yuanta Investment Consulting, who also identified the dot projector as the troublesome component holding back mass production of iPhone X.

Nonetheless, Pu stuck to his view voiced late September that iPhone X will enter mass production in mid-October and begin to be shipped from China in the third week of this month. He is, however, cutting his forecast of the volume of iPhone X that will be produced this year, from 40 million units to 36 million.

Is this much ado about nothing? If this is an actual problem and the issue is not resolved, will Apple push back the current preorder schedule (set for October 27th, just after midnight PDT)? That’s two weeks from today.

Keep your eye on this one.
