Abstract:
Recently, topics such as "iPhone Duo inner screen cracking" and "iPhone Duo screen leakage" have attracted heated discussions.
A netizen posted a video saying that his iPhone Duo broke after being broken twice after activation, and there was an obvious leakage in the center of the inner screen. Such damage occurred just after using the new phone, which also made him feel helpless about its durability.
The netizen then went to Apple after-sales service in Shenyang Vientiane City, but even if he paid for repairs, he could not repair it for the time being. Apple staff told me that there were no accessories and they didn’t know when they would be available, so they could only help register them first.
Apple’s first foldable screen phone, iPhone Duo, reported a screen failure during the first week of sale. The problem may lie in the iPhone Duo’s hinge.
It is reported that the iPhone Duo hinge is composed of precision components such as gears, springs, and connecting metal joints. According to multiple disassembly reports, the hinge adopts the relatively common drop-shaped design. On this basis, Apple added arc-shaped guide rails to control the joint movement. This method reduces the stress on the display when the phone is opened and closed.
In a previous iPhone Duo disassembly report released by iFixit, it was speculated that the cause may be that the central support bar failed to retract correctly when the phone was closed, thereby exerting excessive pressure on the screen.
In addition, the arc-shaped guide rails that guide hinge movement will be higher than surrounding components during the folding process. If the guide rails fail to move as expected, there is also the possibility of interfering with the screen.
According to Jiemian News, the reporter received a response from a Foxconn employee that the cause of the screen failure was roughly similar to the above analysis.
The Foxconn employee also revealed that due to tight production capacity, Apple had previously lowered certain yield quality inspection standards to ensure supply, which will inevitably lead to a higher probability of products with faulty screens entering the market.
He also said that in response to related issues, the iPhone Duo production line has urgently replaced a batch of materials. At present, actual production has not been affected, and the stocking strategy has not been changed yet.
