Issue resolved, stemmed from Apple seeking thinnest device possible
Adding to the mystery of the iPhone 6 and its shipment date, reports are circulating that Apple's suppliers were "scrambling" to source enough screens for the new device, because of a shift in design. Not known is if the problem, linked to the backlight, will lead to shipping delays or extremely tight sales constraints on launch.
According to Reuters, a pair of supply chain sources prevented screen assembly during June and July. Reportedly, a new backlight configuration was not bright enough, so the design and the screen assembly itself had to be changed.
The design has apparently been revised, enough screen assemblies for the 4.7-inch device have been procured, and suppliers are building devices "flat-out" to catch up. Production problems have been previously reported, but with a larger 5.5-inch model. At this point, few concrete specifications of the devices are available, but rumors abound.
