Google Now recently launched on iOS devices giving iDevice users a taste of the personal assistant service and predictive search, although it does not run in the background. Those using Android 4.1 and above can simply swipe up from the bottom of the screen to get to Now, but it's different on the Galaxy S4.

The Galaxy S4 has its own S-Voice assistant. The good news is that using Google Now is not only still possible, but actually pretty easy to do.

You can try the following ways on the S4:

- Just long-press the home key to bring up the task switcher and press the "g" icon at the very bottom of the screen.
- You can add an app shortcut or widget on your home screen. The app can be accessed with a single tap and the Now widget will allow you to view predictive cards without opening the app.
- You can also long-press the menu key when on the home screen to go straight into the Google Search bar and view the Now cards below recent search results.
