This is Microsoft at fault for building a terrible app (and why are we surprised about this), not Android.
I have used my Android phone to call 911 and it worked correctly (though I don't remember if it was the year I had a Pixel or after I went back to Samsung).
It is not Microsoft’s fault. No app should be able to intercept 911 calls. Teams should not have received an actionable event at all here. Microsoft should not have to test the 911 call path.
That the thing though - and I should have been more clear in my original comment.
What if a user installs a third party phone app, with the intention of never using the standard one? That app would have to be able to send 911 calls.
A bug in how the hand off works - yes that's a serious issue. But certainly that's something that we should still hold Teams accountable for testing before they released their app, too.
If a regular user application can break the ability to call 911 from the default dialer, Android is at fault. Microsoft may also have messed up, but the OS failed by letting the bug manifest.
It should be Android’s task to not pass emergency calls to third party apps. Even if you “fix” Teams, any other app still can do it, and you’ll never know.
