android deprecated camera class

I'm using the deprecated android camera object. I read here: https://source.android.com/devices/camera/versioning.html

that even though the camera object is deprecated it should still work for android 5.0+ version. I ask this, because I released an app that uses the deprecated camera object and my friends downloaded the app and it crashes. They reported the errors and I see in the trace stack that the camera can't even open. This app works on my phone and my phone is version 5.0+. So maybe I'm not opening the camera correctly??? Or maybe those phones can't use the deprecated class. Here's my code for opening the camera:

@Override
public void onResume() {
    super.onResume();
    if(!StopTouch)//ignore this condition not relevant to the problem
        StartUpCam();
}

private void StartUpCam()
{

        if(faceProc==null)//ignore this as well
            faceProc = FacialProcessing.getInstance();
        camera=Camera.open(getCid()); //crashes here!!! Calls getCid() which is defined below
        camera.setPreviewCallback(this);
        initPreview(width, height);
        startPreview();
        startTimer();
}

private int getCid()
{
    if(cameraFront && findFrontFacingCamera()>0)
        return findFrontFacingCamera();
    return findBackFacingCamera();
}

public static int findBackFacingCamera() {
    int cameraId = -1;
    int numberOfCameras = Camera.getNumberOfCameras();
    for (int i = 0; i < numberOfCameras; i++) {
        CameraInfo info = new CameraInfo();
        Camera.getCameraInfo(i, info);
        if (info.facing == CameraInfo.CAMERA_FACING_BACK) {
            cameraId = i;
            break;
        }
    }
    return cameraId;
}

public static int findFrontFacingCamera() {
    int cameraId = -1;
    int numberOfCameras = Camera.getNumberOfCameras();
    for (int i = 0; i < numberOfCameras; i++) {
        CameraInfo info = new CameraInfo();
        Camera.getCameraInfo(i, info);
        if (info.facing == CameraInfo.CAMERA_FACING_FRONT) {
            cameraId = i;
            break;
        }
    }
    return cameraId;
}

Anyone else having issues with the deprecated camera class when they release their app? Any ideas what I'm doing wrong here??

If you tried to run it in Android Marshmallow you need to ask for permission dynamically rather than just declaring the Camera permission in manifest. Here's a list of permissions which need to be asked dynamically from marshmallow http://developer.android.com/guide/topics/security/permissions.html#normal-dangerous
