Sorry, I don't have PG for this case because I see every sample work perfectly on even mobile browser.

Please check http://appsbymekong.com/flashdemo/test/ 

It's just a simple scene with a ground. On PC, ArcRotateCamara work perfectly. But on mobile browser (my Google Nexus 6), when I slide the screen, it's just move a little bit and sometime display wrong behavior. 

I think that I miss something but don't know what exactly it is.

Sorry for my poor English.

Here my code (useless code removed): 


<!doctype html>
<html>
<head>
    <title>Porfolio</title>
    <meta name="viewport" content="width=device-width">
    <style type='text/css'>
		html, body,canvas{
			padding: 0;
            margin: 0;
            overflow: hidden;
			width: 100%;
            height: 100%;
		}
    </style>
    <script src="https://code.jquery.com/pep/0.4.1/pep.js"></script>
    <script src='http://cdn.babylonjs.com/2-5/babylon.js'></script>
    
</head>

<body>
    <canvas id='canvas'></canvas>
    
    <script type='text/javascript'>
        var canvas = document.getElementById('canvas');
        var engine = new BABYLON.Engine(canvas, false);
		var scene = createScene();
		function createScene(){
			var scene = new BABYLON.Scene(engine);
			var rayMesh;
			var ambientLight = new BABYLON.HemisphericLight("light1", new BABYLON.Vector3(0, 1, 0), scene);
			var light;
			var cam = new BABYLON.ArcRotateCamera("ArcRotateCamera", 1, 0.8, 180, new BABYLON.Vector3(0, 0, 0), scene);
			cam.upperBetaLimit = 2.0; 
			cam.attachControl(canvas,false);
			scene.activeCamera = cam ;
			
			var ground = BABYLON.Mesh.CreateGround("ground1", 50, 50, 2, scene);
			
			return scene;
     
			}
			
 
  
		scene.registerBeforeRender(function(){
				//cam.alpha+=0.01;
		});
        engine.runRenderLoop(function() {
				
                scene.render();
        });
		 window.addEventListener("resize", function () {
			engine.resize();
		  });
         
		
    </script>
</body>
</html>

I guess you forgot to add css property to the canvas: "touch-action: none"

I think, someone has to capture this in the documentation for the Cameras, where you say that we need to add the css property to the canvas:"touch-action:none"

it will be very helpful then for newbies like me.
