Android Torch only works with front face camera on

Unity Engine
1

Unity 5.5.0p1
I’m working with webcam textures to play with some kind of AR.

//Front Camera
mCamera = new WebCamTexture(devices[devices.Length - 1].name);

//Back Camera
mCamera2 = new WebCamTexture();

Whenever I have the “mCamera2” in Play(); I can’t get the torch to be on.

(I just have 1 camera in Play() at a time)

Here my torch code:

#if UNITY_ANDROID
    private AndroidJavaObject cameraAnd = null;
#endif

    void FlashLightOn()
    {
#if UNITY_ANDROID
        if (cameraAnd == null)
        {
            AndroidJavaClass cameraClass = new AndroidJavaClass("android.hardware.Camera");
            cameraAnd = cameraClass.CallStatic<AndroidJavaObject>("open");
        }
        AndroidJavaObject cameraParameters = cameraAnd.Call<AndroidJavaObject>("getParameters");
        cameraParameters.Call("setFlashMode", "torch");
        cameraAnd.Call("setParameters", cameraParameters);
        cameraAnd.Call("startPreview");
#endif
    }

// the off for the torch if anyone is searching for it

    void FlashLightOff()
    {
#if UNITY_ANDROID
        if (cameraAnd != null)
        {
            AndroidJavaObject cameraParameters = cameraAnd.Call<AndroidJavaObject>("getParameters");
            cameraParameters.Call("setFlashMode", "off");
            cameraAnd.Call("setParameters", cameraParameters);
            cameraAnd.Call("release");
            cameraAnd = null;
        }
#endif
    }

The code works great, except for the fact that only works when there is no active webcam texture OR the front camera webcam is on.

Also while testing I had the torch on, swapped camera and had a crash…
