The fact that Google Now is officially a part of Android 4.1 Jelly Bean hasn’t stopped Galaxy S3 owners from sideloading the app onto their device. Availability clearly isn’t an issue for those who know their way around, but there’s still one app that gets in the way of fully appreciating all that Google Now has to offer — Samsung’s S Voice.
If you’re dead set on saying goodbye to Samsung’s voice recognition app in order to get the full Google Now experience on your Galaxy S3, here’s a method that one XDA forum member,Ghstudent, has helped lay out.
It goes without saying that the method requires you to root your phone. Although this was tested on an AT&T Galaxy S3, it should work on other variants of the phone. There are three steps that you need to follow on the guide, each comes with detailed instructions. The first one deals with how to install Google Now on the device (for those who haven’t done so). The second and third steps are where you’ll be activating Google Now and replacing S Voice.
All the steps are fairly simple to follow. Go to the original thread at XDA to find the guide and links to the necessary files.
