Custom WebView working in simulator but not in physical device. Xamarin

I have implemented a custom web view renderer in Droid project. The issue is, Custom WebView working in simulator but not in physical device.

In physical device WebView load only 1st time not in second time. Even though the android version is same, the physical device and the simulator have different results.

  public class MyWebViewRenderer : WebViewRenderer
    {
        public MyWebViewRenderer(Context context) : base(context) { }
        static MyWebView _xwebView = null;
        WebView _webView;
       
        class ExtendedWebViewClient : Android.Webkit.WebViewClient
        {
            public override async void OnPageFinished(WebView view, string url)
            {
                if (_xwebView != null)
                {
                    int i = 10;
                    while (view.ContentHeight == 0 && i-- > 0) 
                        await System.Threading.Tasks.Task.Delay(10);
                    _xwebView.HeightRequest = view.ContentHeight;
                }
                base.OnPageFinished(view, url);
               
            }
        }

        protected override void OnElementChanged(ElementChangedEventArgs<Xamarin.Forms.WebView> e)
        {
            base.OnElementChanged(e);
            _xwebView = e.NewElement as MyWebView;
            _webView = Control;

            if (e.OldElement == null)
            {
                _webView.SetWebViewClient(new ExtendedWebViewClient());
              
            }
        }

    }

Any help is appreciated. Thanks!
