A new supply-chain report backs suggestions of an iPhone 12 launch in October rather than the usual September timeframe.

Previous reports said that Apple bans on staff traveling to China earlier in the year means there have been delays to two phases of tests needed before mass-production can begin …

At the time, it was suggested that Apple might still be able to launch in September, with limited availability. Subsequent reports indicated that the iPhone 12 launch might have to be pushed back to October, and today’s Digitimes report supports that.

The report goes on to say that production of the lower-end 6.1-inch model will begin earlier than the rest. Displays for this model are reportedly being made by LG rather than Samsung.

There are two possible explanations for the earlier start on these models. First, a contingency to ensure LG can meet quality standards during volume production. LG has experienced glitches with one of its production lines earmarked for OLED iPhone screens and has reportedly struggled to meet both quality and volume requirements. Second, the higher-end displays made by Samsung have a more advanced design which eliminates a separate touch layer, simplifying assembly.

LG is also capable of making this more advanced display, but reports again say the company hasn’t been able to hit the same quality and yield targets as Samsung.
