iPhone 6 Reportedly Entering Final Quality Control Stage Ahead of Mass Production
Previously, a report last month claimed that Apple had already begun mass production for the iPhone 6, however it is possible that reported production issues may have led to delayed testing and output. It is also unknown whether this final testing stage is for both the 4.7-inch and 5.5-inch iPhone 6, as Apple has reportedly had issues in producing the latter's sapphire display and battery life.
Apple's iPhone 6 is expected to be announced at a launch event on Tuesday, September 9. In addition to a larger screen, the device will likely incorporate a thinner, rounded form factor and feature a faster and more efficient A8 chip, as well as an improved camera with stabilization.
