Steps to reproduce the problem:
Recently my Webview based Android application doesn't work properly.

The complaint is that when they press the back button on the device, It should go back to a previous webview url.

But It goes back to a url which is like the user pressed back button twice.

So When I took a look at logs

@Override
public void onBackPressed() {
    WebBackForwardList URL = webView.copyBackForwardList();
    for(int i = 0;i < URL.getSize(); i++){
        Log.d("URL list : " + i, URL.getItemAtIndex(i).getUrl());
    }
}
And with a simulator, It shows all the list of URL that I've entered.

Which is working properly

D/URL list : 0: //https://www.blabla.com/ //First webview
D/URL list : 1: //https://www.blabla.com/catalog/category/view/id/999/ //Second webview
D/URL list : 2: //https://www.blabla.com/brand/bla.html //Third webview
D/URL list : 3: //https://www.blabla.com/44444444.html //Fourth webview
But with a real device like Samsung Galaxy S6, The third and first Urls are missing.

URL list : 0: //https://www.blabla.com/catalog/category/view/id/999/ //Second webview
URL list : 1: //https://www.blabla.com/44444444.html //Fourth webview
It used to work fine several weeks ago.

What is the expected behavior?
