My S4 cames with a basic Google Search bar with a Microphone. The Galaxy S5 has a search bar but its not for a basic web search; its a google assistance system thats want to help you drive, shop, dine and whatever.

I used to use the basic Google Search Bar with the Microphone all the time and I need it on my S5.

 

I didn't really pursue the setup because it sounded so invasive. I finally set it up and found it can be partially simplified, and does provide web search. Still to me "less is more" and I would rather have bare bones version from S4.

Thanks
