here the Xml code

          <WebView
            android:id="@+id/storyText"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" 
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"
            android:lineSpacingExtra="3dp"
            android:scrollbars="none"
            android:visibility="gone"
            android:textColor="@color/black" />

Here is the Java code:

int currentApi = android.os.Build.VERSION.SDK_INT;
mWebView.setInitialScale(0);
mWebView.requestFocus(View.FOCUS_DOWN);
mWebView.requestFocusFromTouch();
WebSettings settings = mWebView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setBuiltInZoomControls(true);
settings.setJavaScriptCanOpenWindowsAutomatically(true);
settings.setDomStorageEnabled(true);
settings.setLoadsImagesAutomatically(true);
settings.setSupportZoom(false);
settings.setAppCacheEnabled(false);
settings.setSavePassword(false);
settings.setPluginState(WebSettings.PluginState.ON);
settings.setLoadsImagesAutomatically(true);
settings.setAllowFileAccess(true);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadDataWithBaseURL("", ftext,"text/html",utf-8,"");              
mWebView.setVisibility(View.VISIBLE);

There are some configurations that make no difference and perhaps you could remove them:

mWebView.setInitialScale(0); // This is 0 by default scale

settings.setAppCacheEnabled(false); // This is false by default

settings.setLoadsImagesAutomatically(true); //This is twice
settings.setLoadsImagesAutomatically(true); //This is twice

settings.setPluginState(WebSettings.PluginState.ON); // This is deprecated since API level 18

If those devices giving you trouble are running on API level 18+ the above line might be the issue.

Then it doesn't seem you are loading the content from a URL despite you are suing this method:

mWebView.loadDataWithBaseURL("", ftext,"text/html",utf-8,""); //The first parameter is empty and could lead to 'about:blank'

Use loadDataWithBaseURL if you are loading from a remote server and have a url, otherwise if you are loading from local then use other methods like: webview.loadData(summary, "text/html", null);

EDIT: Then based on your latest comments, I would save the Urls that the user navigates through in a collection and even save the scrollY in those specific devices. Then listen to the Back button and navigate through the save urls in those devices, reloading the page on each page if needed.

The log provided doesn't show any related entries to the WebView. From the top of my mind I would remove all the settings, and use a loadDataWithBaseUrl with a proper URL. Otherwise if you could provide the URL then I could check it out myself. — Juampa, Feb 04 '16 at 20:01
Thanks Proverbio,I removed all the settings and use loadDataWithBase Url but its device specific problem.everything is fine most of the device but problem only Xperia and moto X device.first time all contents loading but rendering to webview page to another page and then by back button come to webview page then webview data is showing blank this is the problem — Vijay Prakash, Feb 05 '16 at 05:48
