Google Search has been updated to bring several new features to Google Now for phones running Android 4.1 Jelly Bean and above. The new version allows you to have short conversations with Google Now, and it replies back if there are several results to your query. You can also trigger Voice Commands by saying "OK Google" instead of tapping on the mic icon.
The new update also integrates updates from Waze, a popular crowd sourced real-time traffic monitoring service as well as new cards for updates from websites, notable people or news topics. The new Google Search app is also compatible with Google Experience launcher which comes with the Nexus 5 and also leaked a few weeks back. There are many underlying things, hit us in the comments below if you have discovered something new after the update.
