Yes, exactly. In several version iOS, Android ( old), history.back() seem not working. To fix it, you should try this code ( i find it in JQM @@ and it working well for all )
var nav = window.navigator;
if( this.phonegapNavigationEnabled &&
nav &&
nav.app &&
nav.app.backHistory ){
nav.app.backHistory();
} else {
window.history.back();
}
solved history.back() not working in phonegap ios build
