On multiple devices when doing system update on ios 26, pin entry displays full keyboard instead of standard pin input. It's been like that for like 5 versions (of iOS 26) already.
It's fascinating to me because that's the single thing which every user goes through. It's the main branch and not some obscure some edge case. How do you do testing that you miss that?
You can also use an alphanumeric passcode, in which case you need the full keyboard. Maybe they just unified this, so that it always displays the keyboard instead of switching between keyboard and PIN input?
I mean it should be unified, the pin entry should look the same in every place, this has security implications also. It doesn't.
