How do I disable Google App? I'm using Android 6.0 (non-rooted) phone. Holding home button opens up Google App which I never use.

I don't think that I can change the behavior of holding home button at least as non-root user. (If there's any way or work-around then don't forget to tell me!)

So, as I never use Google App and also want to stop opening Google App by means of home button, I want to disable it as it is a system application hence I can't uninstall it.

But when I opened Google App from system settings, I found disable button is disabled:



So, How do I disable Google App or there is no option except root?

By the way, it is also not being force-stop with the help of force-stop button!
You can change the behavior of holding home button even as non-root user (at least on my LG G Flex 2 with Android version 6.0.1):

Settings - Apps - Configure apps - Default Apps (in Advanced section) - Assist &amp; voice input - here touch the text "Assist app Google app" not the icon on the right edge - here select None.
