Fingerprint sensor issues to delay iPhone 5S production?

Supplier sources who expected mass production of the next iPhone to begin in June now believe that date may be pushed back, according to Reuters.

The possible delay in producing the iPhone 5S is due to Apple’s search for a coating material that doesn’t interfere with a fingerprint sensor, according to a “supply chain source.” Sources also said small-scale production of the budget iPhone will begin in May, with mass production starting in June.
