Issue
When I look at the stack trace of an event with title "App Hanging" it looks like its just reporting the stack trace of the first non-Sentry thread in the process. Is this supposed to be the culprit thread?
Applies To
Sentry users using the App Hangs integration
Sentry users with issues titled: "App Hanging" or "App Hanging for at least 2000ms"
Symptoms
The reported stack trace for App Hanging events seems arbitrary.
Resolution
This can be expected behaviour under certain circumstances.
If the main thread is extremely busy with different code spots, the app hang detection might fire a bit too late. If this happens, the SDK may record a stack trace that isn’t 100% related.
You can navigate and filter threads using the threads selector (found just above the Thread's stack trace in the UI):
