Can't you get just your iPhone screen repaired?

I don't think so these days. I remember a little while ago, an update was pushed that bricked any phones with a third party screen (which I think included the finger print reader). The update was patched I believe but replacing the screen on a modern iPhone isn't as simple as replacing the glass anymore IIRC.

I think the Touch ID assembly is considered part of the screen.

The aluminum iPhones (and other phones) were so beautiful. I have an old HTC M8 and it just looks and feels so nice compared to all glass Samsungs. Plus the front facing stereo speakers - truly practical.

Glass backs are a requirement for wireless charging, it doesn't go so well with metal.

IIRC anything with the fingerprint reader gets complicated because of the signing keys Apple uses to help protect the device against unlocking attacks.

There is nothing complicated about simply not having a fingerprint option. If the main machine knows it cannot trust the fingerprint secure enclave, then there is nothing complicated at all about simply, not trusting it. The user simply has to unlock the phone with a pin or pattern etc. This does not, in anybway, require bricking the device. That is simply a deliberate and hostile act of aggression against the user.

Yes, but how does the phone know the TouchID sensor has been switched by a Good Guy and not an attacker?

Security has drawbacks.

> Security has drawbacks.

Not really an argument for saying an implementation isn't possible.
