> [@Johnny13](#): > > history.back(); Why?? Ionic is already an amazing thing which tracks the pages, handles the stack of the pages so when you press a back harware button you go to the previous page. If you wish to go navigate back manually (without harware button). You can you use [pop](https://ionicframework.com/docs/api/navigation/NavController/#pop) method, it removes the page from the stack. 🙂 ---

When I click the browser back button, it will throw the same error。 ---

I think angular alone is enough for that. Ionic is Angular+Cordova and cordova is useful only in devices. ---

There was no problem with previous versions of ionic , So how can I do？ ---

Ionic is much more than just Ionic+Cordova. If you only want to use Cordova, that is fine - but please don’t impress that on others, especially if they are asking for help. ---

Can you please create a new project with `ionic start blank blank` and see if you can reproduce the problem there? ---

No changes to the blank project and you get an error when you use the back button? (How do you do that with no pages to navigate to?) ---
