A new report has highlighted that Apple’s second EVT phase or ‘Engineering Validation and Testing’ phase for the iPhone 12 range will be completed by the end of June, with the production stage apparently starting from the month of July.

Assuming the report turns out to be true, Apple most likely wants to commence production as early as possible to prevent unnecessary delays in the future. Then again, the company’s supplier Broadcom believes the iPhone 12 family will be delayed this year, but it’s possible Apple is attempting to secure the month of September for its official unveiling.
