Yes

Have you set an ErrorCallback?
Does it happen only when you are setting camera manually or anyway?

from code-scanner.

mCodeScanner.setErrorCallback(new ErrorCallback() {
            @Override
            public void onError(@androidx.annotation.NonNull Exception error) {
                Log.e(TAG, "QR Code Reader View: " + error.toString());
            }
        });

I am using android device with API 19, i.e., Kitkat 4.4.4

from code-scanner.

Can you take a screenshot with stack trace?
ex:
Log.e(TAG, "QR Code Reader View: " + error.toString(), error);
or
error.printStackTrace();

from code-scanner.

And also, Code Scanner will use first bask-facing camera by default.

Are you using cmera only by Code Scanner or not? Probably, you haven't released the camera before usage. Also, will be good to take a look at your source code.
