A YouTuber dissected an iPhone Duo and thinks he found the cause of crackgate. A weak spot in the hinge may be failing and cracking iPhone Duo screens.

一位 YouTuber 拆解了一台 iPhone Duo，并认为他找到了“裂屏门”的起因。铰链处的一个薄弱点可能正在失效，从而导致 iPhone Duo 的屏幕破裂。

Social media and the iPhone Duo subreddit are filled with reports of Apple’s foldable failing quickly and in spectacular fashion. Some users report having the phone for only a few hours before the hinge seems to catch on something, then audibly crack and break the screen. Tellingly, the cracks all seem to happen in the same place.

社交媒体和 iPhone Duo 的 Reddit 子版块上充斥着关于苹果这款折叠屏手机快速且严重损坏的报告。一些用户反映，手机才用了几个小时，铰链似乎就卡住了什么东西，随后发出破裂声并导致屏幕损坏。值得注意的是，这些裂纹似乎都出现在同一个位置。

YouTuber CuriousHagi was able to reproduce the cracked screen during some durability testing of the iPhone Duo. Then he pulled it apart to try and find the culprit. What he found is that the Duo’s hinge is quite complex, consisting of a gear-like central hinge and two different types of linking hinges.

YouTuber CuriousHagi 在对 iPhone Duo 进行耐用性测试时，成功复现了屏幕破裂的情况。随后，他将手机拆开以寻找罪魁祸首。他发现 Duo 的铰链非常复杂，由一个齿轮状的中央铰链和两种不同类型的连接铰链组成。

The piece that broke is one of the links in the middle of the phone that happens to be thinner than the links below or above it, and it snapped at a small notch where it would be weakest. He also found marks where the hinge met the support plate, indicating where it may have gotten caught.

损坏的部件是手机中部的一个连接件，它恰好比上下方的连接件更薄，并在最薄弱的小凹槽处断裂。他还发现了铰链与支撑板接触处的痕迹，这表明了铰链可能是在此处被卡住的。
