Apple Inc. (AAPL - Get Report) is only producing 20 million iPhone X units this year, meaning it will drastically whiff on its production goal of double that, according to a report in the Nikkei Asian Review.

The company had previously planned for close to 40 million iPhone X models to ship by the end of 2017. Production has run into issues concerning the phone's face-scanning sensor technology.

The company is able to make about 10 million iPhone X units per month at current levels, the Nikkei said, after manufacturing yields improved at the end of September.

The iPhone X is Apple's 10th anniversary rendition of the handset. It was unveiled in early September to much fanfare, but analysts have expressed production concerns revolving around the phone's lofty high-tech features. The iPhone X will be available Nov. 3 with a base model price of $999.

Apple stock was slightly lower 0.09% to $156.03 in premarket trading Tuesday, Oct. 24.
