Specific url does not load in WebView from Samsung Note2

I am loading url in webview which works fine on all devices except Samsung Note2. It's not loading and showing a webpage in Samsung Note2, but the same code works great for all devices. I cannot find the exact reason for this. Please suggest me any solution.

My WebView code:

mWebView.setWebViewClient(new MyWebViewClient(this));
mWebView.setWebChromeClient(new WebChromeClient());
private class MyWebViewClient extends WebViewClient {

        private int refreshCount;
        private Context m_context;
        private long m_start;

        MyWebViewClient(Context context) {
            m_context = context;
            // pDialog = new ProgressDialog(m_context);
            dialog = new Dialog(m_context);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        }

        @Override
        public void onReceivedError(WebView view, int errorCode,
                String description, String failingUrl) {
            // TODO Auto-generated method stub
            super.onReceivedError(view, errorCode, description, failingUrl);
//          Toast.makeText(m_context, "Network Problem", Toast.LENGTH_SHORT).show();
            //          CommonMethods.showNetworkErrorMsg(WebPayUActivity.this);
        }

        @Override
        public void onReceivedSslError(WebView view, SslErrorHandler handler,
                SslError error) {
            super.onReceivedSslError(view, handler, error);
            handler.proceed();
        }
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {

            view.loadUrl(url);
            return true;
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);

            try{
                m_start = System.currentTimeMillis() * 60;
                Window window = dialog.getWindow();
                window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

                dialog.setContentView(R.layout.pdialogcustom);
                dialog.getWindow().setBackgroundDrawableResource(
                        android.R.color.transparent);
                dialog.setCanceledOnTouchOutside(false);
                dialog.setCancelable(true);
                dialog.show();
            }catch (Exception e) {
                // TODO: handle exception
            }

        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            try {
                dialog.dismiss();
            } catch (Exception e) {
                e.printStackTrace();
            }

        }
    }
