As far as I know, this bug only affects the X, XR, XS and XS Max models.
Most people in this thread, including the OP, did not mention what phone they had. As the original post dates from before the release of the iPhone X, it's safe to say the OP didn't have one. Of the posts that did mention a model, 15 mentioned the iPhone X, 4 the XS and 1 the XS Max. Twenty-one people, on the other hand mentioned other models, including iPads. Not surprisingly, the number of X family phones increased as the thread got older.
The truth is (as several people noted in this thread) that there have been reports of alarm problems for years. However, as they appear to affect only a very small percentage of phone users, it's challenging to figure out what the causes are. And yes, there is more than one cause.
