Front camera default display

I have an app that takes pictures with the method: Ti.Media.takePicture ();

when the camera is launched with a button I can change the front camera and take the picture with this code:

var = Ti.Media.availableCameras cameras;

for (var c = 0; c <cameras.length; c ++) {  // If we have a rear camera ... we add switch button  if (cameras [c] == Ti.Media.CAMERA_REAR) {         overlay.add (btnConfiguracion);         overlay.add (btnCompartir);         overlay.add (cameraType);                  //cameraType.addEventListener ('load', function () {         cameraType.addEventListener ('click', function () {                  // When switching from camera stop and restart counters         if (inicioConteo == "yes") {         inicioConteo = "NO";         clearInterval (conteoTomarFotoFijo);         segundosContadorFijo = 7; conteoRegresivoFijo ();         }

 if (== Ti.Media.camera Ti.Media.CAMERA_FRONT) {                //cameraType.title = "front";                Ti.Media.camera = Ti.Media.CAMERA_REAR;                Ti.Media.switchCamera (Ti.Media.CAMERA_REAR);         } Else {             //cameraType.title = "rear";             Ti.Media.camera = Ti.Media.CAMERA_FRONT;                 Ti.Media.switchCamera (Ti.Media.CAMERA_FRONT);           }         });

but when you start the camera again looks back camera again, you can set if you have front camera always start this
