I hope the EU will eventually put an end to this nonsense. Apple is going way too far with these unnecessary restrictions.
Amazing how nobody even read the article (even macrumors had to offer an update on this point 
). He switched the Original screens between two brand new iphones! I guess you don't become the richest company in the world without nickle and diming your customers for every conceivable thing possible.

That doesn't sound like good news to me. Sounds like a very bad day. Apple needs top consider that not everybody lives near an Apple store or authorised dealer.
In any case, those raising the issue of security: has a third party screen for the iPhone ever had an embedded chip that stole the iPhone user's information? I genuinely don't know.
Don’t know why people think this is new. Pretty sure this has always been the case when any part of the security chain is replaced all the way back to replacing TouchID buttons.
You can argue if it’s too much security since security is always a balance between being secure and being convenient, but from a purely security standpoint, this is to avoid a bad actor from connecting altered hardware to try and bypass the security protections.

Right attitude but unfortunately it is the small minority of people that make the mistakes which forces changes that takes away the rights of everyone else..
Firmware update would fix this issue. Remove the security check where the screen has to be the factory installed screen, problem solved.
Sounds like Apple intentionally did this to prevent 3rd party provider from replacing the screen, even if it's jen-you-wine app-pill.😑 Apple probably does a firmware patch where they change the valid checksum on the phone to match the new screen's ID checksum.
No sideloading, CSAM, overpriced, now this. Too many straws, Apple; y'all broke the camel's back. Broke it's back! I guess it's time I talk my wife out of replacing her current iPhone with another in the future.

In this era of increasing scrutiny of everything Apple, I do not think it's this. I can't hazard a guess though as to the reasoning behind this.
And don't have insurance such that one has to take it to a third party repair shop.
See post #79.
He does a bit on how it all connects together.
The display is separate.
This is not about security.
This is about control and money by not allowing third party repair work.
Apple could very easily sell OEM parts for repair to be done by users or Authorized shops.
We.
Need.
Right.
To.
Repair.

What silly thing to do…
Even if it’s their product and they’re free to do whatever they want it feels like there should at least be a reason for acting this way.
I understand being overzealous over a replacement camera or touchID sensor but the screen?? Crazy.

There is for that reason, people will get their phones fixed from a shady source and then claim to apple that it was defective, your simple apple genius rep would just replace it and give you another one back then.
Now every single component is numbered serially that if it authorized retailer doesn’t rewrite the part to work with the hardware it will not work at all!
"As discovered in a repair video, the iPhone 13 screen includes no components for Face ID to function"
That is not correct. The glass itself is an optical component in the optical path for the Face ID dot projector and the infrared camera. Light passes through the glass from the dot projector, and then through the glass again on its way to the IR camera. The alignment combined with any wedge in the glass will deflect the path of light slightly differently from screen to screen, impacting where those dots land and what the infrared camera sees.
What I don't know is what the alignment tolerance is the dot projector and IR camera and how that flows to the wedge requirement in the glass itself and the opto-mechanical alignment terms in the mechanical interface from the glass to the mount form the mount tothe rest of the phone enclosure and from the enclosure to the IR camera and dot projector pointing.
It is possible that each combination of enclosure plus screen goes through some sort of FaceID factory calibration that is stored in the FaceID system. This could be why FaceID refuses to operate: it detects that the calibration is not matched to the part and Apple being Apple decides to turn off Face ID rather than possibly have a sub-optimal user experience.
Or it is possible the required alignment for the dot projector and the camera is loose enough that the phone can just be snapped together as long as all the mechanical parts and the glass meet specification and FaceID will work without any special calibration, and Apple just put some fussy software hook in to disable FaceID when someone gets a new screen.

If there is wedge in the glass and there is a finite tolerance as to how the glass mounts relative to the phone enclosure from glass to glass, then light coming to IR camera and from the dot projector will steer differently on its way to and from the face being sampled.
Apple offers a product (an iPhone). By purchasing a product from Apple, you accept Apple's offer and an agreement is formed. The contents of that agreement (Apple's and the consumer's rights and obligations) are contained in the terms of use (and the law).
Nobody forces you to buy an iPhone. But if you buy one, you agree that you're buying a phone that you can't just have repaired everywhere, you know that in advance. Property law means that you can (in principle) do anything you want with your iPhone. If you want to have it repaired by your neighbor, you can, no one can stop you. But you know that you may not keep all the features if you don't do this with Apple (or its partners). Property law only says something about your relationship with a business, but it doesn't give you a claim against Apple to keep your property working forever and unconditionally, regardless of who you let tinker with your iPhone.

This issue is not a new to iPhone 13. My iPhone XS does the same thing and was replaced by Apple. If you don't remove the original TrueDepth sensor and add it back to the new screen FaceID will always be disabled. It supposedly contains all the original codes and scans for that particular phone.
Update: According to the video mentioned below, even if an iPhone 13 display is replaced with a genuine and original iPhone 13 screen, Face ID will stop working. In the video, the repair provider swapped two original iPhone 13 screens and in both cases, Face ID was inoperative after the new screens were installed. It seems to be the case that if the original screen is put back with the original iPhone 13, Face ID returns, ruling out the possibility of an improper installation.
If a customer gets their iPhone 13 display replaced by a third-party repair store or provider, such as those not licensed or affiliated with Apple through its Independent Repair Program, Face ID on the iPhone will no longer be useable.
Apple has long faced criticism for making it difficult for third-party repair stores and providers to fix and repair their products. Apple already displays a prompt for customers inside Settings that informs them that their display is a "non-genuine display," and a similar prompt for "non-genuine cameras" was introduced earlier this year.
Apple claims these prompts help inform customers that they aren't using genuine Apple parts and is part of its more comprehensive plan to ensure customer devices are only repaired and diagnosed by certified Apple technicians.
With the iPhone 13 this year, Apple further makes it more difficult for customers to get repairs from third-party stores and providers. As discovered in a repair video, the iPhone 13 screen includes no components for Face ID to function, as all the parts for the TrueDepth system are housed in the iPhone itself.
Despite this, if an iPhone 13 display is replaced with a "non-genuine" or even a genuine, original iPhone 13 display, Face ID stops working, despite there seemingly being no hardware within the display itself needed for Face ID to function.
Apple runs its own Independent iPhone Repair Program, which is designed to allow any company or third-party repair center to become an authorized Apple service provider only if they meet the requirements and go through the process.
Apple has expanded the program to more countries worldwide, but compared to fully independent third-party repair providers, authorized Apple outlets often have higher prices, longer wait times, and poor customer service. Companies and stores certified through Apple get access to genuine Apple parts, manuals, and device instructions, including information not available to third-party repair stores.
Given the lack of hardware reasoning for the iPhone 13's Face ID to no longer be usable after a third-party screen is installed, Apple could patch this via an iOS update if it's a simple iOS 15 bug. Keeping in mind its past efforts to consolidate iPhone repairs to only stores and centers it chooses to consider "authorized," however, this is unlikely to be a mistake and will only further fuel the Right to Repair movement. We've reached out to Apple for comment.

Sure, but as Apple keeps piling on the user-vindictive attitude they may well find people do exercise their right not to buy their hardware. I am holding off upgrading my iPhone and buying a MacBook because of Apple's recent actions, which is a shame because I was saving up over lockdown for new kit.
I imagine this has something to do with the display needing to go through a calibration machine that links the display with the logic board as Apple has done since 2013 with the iPhone 5. Not sure why all of a sudden with this model they've decided to disable the True Depth system since others have had replaceable displays with Face ID.
Correct, which is why Apple requires authorized shops to do (rather than some random shop Apple has no knowledge of) so they can use the equipment that resets the indicators on the phone that removes the security warning.
