Not a good solution but I register back button action before calling any http call using registerBackButtonAction function & deregister it in http response or error.

```auto
registerBackButtonAction(){
    this.unregBackCall = this.platform.registerBackButtonAction(() => {

    }, 100);
  }

  removebackbtnaction(){
    this.unregBackCall && this.unregBackCall();
  }

```

Ionic team should add disabling back button action while loading controller is showing.

Thanks
