All phones likely have bugs which could lead to crashes which means it could in theory just happen to experience an issue concurrently with the users attempting to call 911 resulting in a failure. However your base image should have few to zero such bugs and such failures just happening to coincide with an emergency call are or ought to be statistically very unlikely.

The issue is not that a crash could happen its that a specific crash happens specifically when the user tries to place an emergency call triggered by the code that is supposed to run when the user makes such a call making failure statistically much more likely. Worse this has been a known issue since 2021.

People aren't asking for space shuttle quality engineering they are asking for the same statistical probability of failure as any other good quality phone. It is deeply ironic that while you insist others don't know what they are demanding you clearly have no idea what they are demanding.
