Ah, ok, that makes a lot more sense, but I still have concerns about how this is a critical breaking fix, affecting so new devices.

Google seems to have a worrying amount of emergency call problems with their Pixel line, so it doesn't seem to be limited to Samsung.

Google claims they've fixed that in the latest update:

I was tracking that because I'm a pixel owner, though the one time I've had to phone I've not had an issue.
