In April this year, there was news that Apple’s first foldable screen mobile phone, iPhone Ultra (iPhone Fold), had entered the trial production stage at Foxconn. Trial production is an important step before the product is officially mass-produced. It generally needs to go through engineering verification, design verification, production trial production verification, and finally enters formal mass production. Recently, blogger "Sena Digital" revealed that the iPhone Ultra has indeed encountered obstacles in its recent trial production phase.
According to him, Apple has basically accepted the current plan for the screen crease issue that is of concern to the outside world.
From the test results,The machine has been able to achieve "long-term stable maintenance" of visual crease-free status.
However, it's the hinge that really stalls the progress.
The current core difficulty with iPhone Ultra is hinge reliability, the blogger said,After long-term high-frequency opening and closing tests, the performance of the hinge has never reached Apple's quality control standards. This mechanical loss must be solved perfectly, otherwise the project progress will only be temporarily delayed.
It is understood that in response to the common crease problem in folding screen mobile phones, iPhone Ultra was previously rumored to use a liquid metal hinge to reduce the visibility of the crease while improving structural strength and durability.
Based on current breaking information,The iPhone Ultra is expected to adopt a horizontal inward folding design, with an approximately 5.3-inch outer screen and a 7.7-inch inner screen, and will debut the A20 Pro chip.
The chip is expected to be built based on the 2nm process. If it goes well, the iPhone Ultra will become Apple's first heavyweight product to enter the folding screen mobile phone market.
