Google Instant has been updated to work with Android 2.2 and iOS 4.0 and higher. It works just like the desktop version, and can easily be disabled if it’s not your cup-of-tea. To test it out, just go to Google.com, and turn on “Instant (beta)“. It functions quite well, and makes searching much faster—especially on mobile devices.
Like the desktop version of Google Instant, when you type on your mobile device you’ll see predictions of what you might be searching for. If you type [anse], for example, you should see [ansel adams] along with other predictions. Results for the first prediction appear automatically, and tapping on the other predictions will display those results. Pressing the enter key or the search button skips the predictions and will display results for exactly what you’ve typed.
