Error value 3 is ERROR_CAMERA_DISABLED.

The latest versions of Android do not allow camera access while in the background. There's a short delay before enforcement happens when your app goes into the background, but eventually you'll be disconnected and receive that error code.

To keep the camera open, you need a foreground service at the minimum, which means you have to have a notification running for your service, to inform users that your app is actively doing something.
