The firm says that Google Instant makes search faster by displaying not just predictions but actual search results as you type.

“This saves valuable time on a desktop browser, but wouldn’t it be great to have Google Instant on mobile devices, where each keystroke and page load is much slower and you frequently have just a moment to find the information you need?” said Steve Kanefsky, Software Engineer.

Google Instant is said to work best on 3G and WiFi networks, but as the quality of any wireless connection can fluctuate, there are options to turn the search feature on or off.

Google first announced its plans to bring Instant to mobiles in September. A beta version has now gone live in “to most” iPhone and Android devices in the US but word of a wider rollout, especially into New Zealand, weren’t given.

“We’re working to support additional countries and languages and more devices in the coming months,” added Kanefsky.
