Is it a Google issue or a Qualcomm issue ? (e.g. does it occur when using Calyxos/GrapheneOS/LineageOS instead of the raw Google Android OS ?)

The Pixel 6 has a Samsung SoC and 5G modem. If the Exynos based Samsung phones were also affected you'd have heard about it a lot more and earlier.

Let's just spell it out instead of this clickbait title: Dialing the local emergency number (112, 000, and 911 were reported, but presumably also others) sometimes doesn't work, just gives a click instead of dialing. Google blames third party apps. Users report similar issues since Pixel 4 that were reported to Google but haven't been resolved since release. Not like "911 doesn't ring" is much longer of a title than…

Nothing about your explanation refutes that this is a very scary issue.

Third-party apps or not, a phone that can't call emergency services in every situation other than empty battery should be treated by the government like food that can potentially poison people.

It's a side effect of that Android version letting apps register to take over calling functions (for, e.g., VOIP purposes). If any such app on the phone doesn't handle the emergency call case correctly, then the attempt fails in one way or another.

Is there any theory or explanation why this happens? "Third party apps" is totally vague, what third party app could stop you from dialing an emergency number? And even if such apps exist (or even are common) is it not a huge design flaw by itself, which the manufacturer has to remedy?

Not sure why they don't say it by name but the bug was originally found with MS Teams. "The issue is the result of an “unintended interaction” between Teams and Android, specifically when the users have the app installed but are not logged in to any account."

Thanks! Still very weird to be honest.

It's not a network problem. It's a side effect of that Android version letting apps register to take over calling functions (for, e.g., VOIP purposes), when then makes emergency calls fail if any of the apps that have registered that functionality don't handle it properly.

Why does Android allow apps to take over emergency calls?

This article, dating back to January, lays it out pretty clearly: https://arstechnica.com/gadgets/2022/01/google-fixes-nightma...

> If you're logged out, launching Microsoft Teams 10 times will result in 10 duplicate PhoneAccounts from Teams clogging your phone. Teams shouldn't do this, and Microsoft's update stopped Teams from doing this, but a bunch of duplicate PhoneAccounts also shouldn't be enough to bring Android's phone system to its knees.

> Next bug: when picking a PhoneAccount to run the emergency call through, [...] it's possible for this to result in an integer overflow or underflow, and now the phone subsystem is going to crash.

> A third bug in this mess is that Microsoft Teams does not even register itself as an emergency call handler.

> An update is not arriving for the Pixel 6 yet. Google's newest flagship is going though a bit of an update crisis at the moment. The December 2021 update was pulled due to unrelated "mobile connectivity issues" (phone calls don't work). While Google scrambles to fix everything, the next Pixel 6 update with this 911 fix is due in "late January." Until then, it's normal to be on the November patch. Both of Google's "early January" and "late January" patch timelines seem incredibly slow for a bug that could cause users to literally die.

If the OP article is correct, then apparently this still hasn't actually been fixed yet.
