Google may have several products on its portfolio, but its primary business is just one, Search.
And the Mountain View company is offering users the chance to test the beta version of its search app for Android devices.
How to download the Google Search Beta app:
Go to this page, which asks you if you want to join the beta program. You must be logged in to your Google account to join the program, which you can do so by clicking on the “Become a tester” button.
Now open the Play Store app on your Android phone or tablet, it should say a new version of the Google Search App is available for download.
The beta version doesn’t seem to have anything new, but you will be among the first to get the new features, before they are rolled out to the general public.
