The following crashes occur only on Android 16 devices when the app is in the background state (100% based on Firebase Crashlytics, check the attached screenshot).
My application is a video recording app that runs with a foreground service, which allows it to continue working (using camera) while the app is in the background.
The crashes are reported by Firebase Crashlytics, so I have not been able to reproduce the issue yet or provide a minimal sample project.
The app currently has about 600,000 installed users. According to Crashlytics, the issue has affected 109 users (319 events) so far. So far, it happens rarely, and I can't reproduce it on the same devices.

From a Android developer perspective, CameraManager.getCameraCharacteristics() should be safe to call at any time and should not depend on the application task state.
