According to BlueFin Research, the production of the new iPhone 8 will begin much earlier than in the past, given that Apple expects very high demand and want to avoid as much as possible to have problems with the procurement.
This does not mean that the iPhone 8 will be released first, but only that Apple wants to take more time to produce it. Such production should begin as early as the end of May in China, so as to have at least 10% more devices at launch.
We are confirmed some rumors that we already know, including the presence of curved OLED screen on at least one of the new iPhone coming out later this year. In addition, analysts believe that the iPhone 8 could exceed all sales records later this year.
