OK I SOLVE.

If you want to use WebVR (Browser which support VR (with javascript navigator.getVRDevices())
 

(MOBILE for CarbonVR) or just Mobile (If you dont have VR DEVICE/GOOGLES)

FOR ANDROID
You have to download "Chrome Canary (Unstable)" and then In the URL bar, load chrome://flags#enable-webvr and toggle the Enable WebVR flag.

(here: https://webvr.rocks/chrome_for_android) after that you restar chrome canary and Babylon WebVR works (left/right side). (so only so WebVRFreeCameraID works OK else browser not supporter.... to new..)

WebVRFreeCamera is using the WebVR specification available in Edge Creators Update, Firefox 55 and some specific build of Chromium. It's also available on Gear VR and DayDream. It better address WebVR devices and also expose gamepad extesion to use the VR controllers.

VRDeviceOrientationFreeCamera is a fallback camera based on the Device Orientation API. It mimics a bit the WebVR one using the accelerometer of the smartphone and doing a double rendering of the scene with lens distortion handled (can be disabled). 

You need to feature detect WebVR in your code to use either WebVR or Device Orientation. Here's a sample showing the best practice to use (using Sponza as a demo): http://playground.babylonjs.com/#QWIJYE#1
