Google has added Instant Previews for search results on mobile devices, including Android phones. If you do a search on Google, and click the magnifying glass next to a search result, it will bring up a visual preview of the results that is easily scrollable. This makes it much easier to find something if you know you're looking for a specific type of content or graphic.
For Android, Instant Preview is compatible with devices sporting Android 2.2 and up and is available in 38 different languages.. If you have Froyo and above, just go to Google.com in the browser and do a search. You should be able to see the magnifying glass that will allow the Instant Previews. [Google Mobile Blog]
