在iFixit最近对iPhone12的拆卸中发现，如果用户更换摄像头模块，新**会遇到一些问题，如果没有苹果授权维修商更换，基本上会导致设备上的摄像头无法使用。

iFixit经常公开反对消费电子企业对产品维修的控制，主张对维修权进行政策调整。在其网站最近的一篇帖子中，它质疑iphone12是否是“可修复iPhone的终结”

在本周的科技评论季**播客系列的最后一集中，Vergecast的Dieter Bohn与iFixit的Kyle Wiens和Kay Kay Clapp讨论了他们对苹果最新产品的可修复性的看法，以及对修复权的争夺，以及它如何操作著名的撕裂。

下面是这段对话的一段经过简单编辑的摘录。

It looks like Apple has done something with the camera module specifically, where it makes it harder to replace the camera module. Can you explain what’s going on with this camera module thing?

Kyle Wiens: Sure. So when we do our first teardown, we open it up. We’re looking at, mechanically, how do we get in. The rating we provide is generally based on just how easy it is to open, how can we get to the components.

We did some light compatibility testing where we took two different iPhones, and we swapped the batteries between them to see if they would work. We took [an iPhone 12] battery, put it in an 11 to see if it will work, that kind of thing, just to get a feeling of how they design the phone, what their supply chain is going to look like, but we don’t extensively go and swap every single component.

After we published our teardown, Hugh Jeffreys in Australia, a popular YouTuber, did some more extensive testing, and he started swapping more components. He took the camera out of one iPhone 12, put it in another, and it didn’t work — or it worked but in a very glitchy way. That was sort of eye-opening to us. And then we got leaked a document from Apple’s internal service saying that in order to repair the camera the official way, you have to have Apple software to pair the camera to the phone.

Interesting. So some part of the iPhone — maybe it’s their secure enclave, maybe it’s just like the logic board or something — needs to identify the specific camera part, and Apple needs to approve that pairing through some sort of cloud process in order for the camera to actually work. Is that right?

It’s possible that’s how it works. That’s how the Touch ID sensor works. It’s also possible that there’s just a calibration procedure. There may be a very precise signal timing. So to put the phone into a sort of pairing mode and say, “Hey, listen to the signal timing, and sync up precisely with the camera.”

So it’s the kind of thing that you do at the factory, right? You hook everything up at the factory, and then they’ve got the tooling.

And this is True Tone works. Every LED that you make is going to have slightly different performance characteristics. And so the way that True Tone works is at the factory after they make every screen, they tune it a little bit for that specific phone and then they write that configuration to the phone. And that way, you get more c***istent color. It’s possible they’re doing something like that with the camera.

So there’s nothing wrong with that kind of pairing procedure. The problem is when you have a process like that and then you don’t make that tool available to the owner of the phone, now all of a sudden, we’re in a situation where I’ve got this iPhone 12, we swapped the camera, you can see this one camera is working fine. And then I go in portrait mode and switch to the other camera, it just crashes the whole camera app.

就在我们周五录制完这一集之后，当被问及相机互换问题时，我们得到了苹果公司的一份声明：

“我们致力于为客户提供更多安全可靠的维修选择和地点。我们新的独立维修供应商计划旨在为各种规模的维修企业提供执行最常见的iPhone维修所需的原装零件、培训和工具。这些服务提供商可以使用苹果和授权服务提供商（AASP）使用的相同工具和维修手册。”
