Apple suppliers are ‘scrambling’ to ready screens for the iPhone 6, says Reuters, after a late component change required a redesign. The website’s sources said that Apple wanted to use a single layer of backlight film in the 4.7″ version of the handset to keep it as thin as possible. However, the phone was not bright enough and had to be redesigned to fit the extra layer. It is not clear whether the delay will affect supply to consumers, according to the sources.
