Perhaps because there's limited storage space in the SEP for multiple face models?
Perhaps because the angle of the IR spreader hidden in the notch cannot cover the face in earlier models?
Jeesh, do people not realize that this stuff actually runs on HARDWARE?
And that this HARDWARE changes from one year to the next?
I think the problem is it can be both, and sometimes consumers are fed half truths to cover it. When this happens one time, people will always remember that the next dozen times hardware is used as an excuse.
The iPad Pro is able to utilize landscape and portrait Face ID (my M1 can, not sure how far back it goes), but cannot perform masked Face ID unlock.
We were told apple was unwilling to add Touch ID back to new iPhones as it was not as good or not as secure, and in the power button was bad.. now it’s in iPads.
For two years we heard about underscreen fingerprint scans coming because Face ID couldn’t deal with masks. And we were told it wasn’t really feasible and if we bought an Apple Watch it would unlock without needing a password or Face ID. Then magically it came in a software update.
With Apple’s increasing focus on profits/margins, the software crossover between IOS and iPadOS plus the hardware shared between models, I always take Apple’s reasons with some salt.
I’m not furious over these things, more so wondering what is actually the reason.
