So i rooted my nexus twice and each time Google now would stop working and stop being responsive. For example when i say okay Google nothing happens, if i press the mic the white card comes up but don't respond to my voice, and when I go to the cards everything is empty. To fix this i must clear the data of Google search or turn my phone off and back on. Right now I am not rooted and I'm not having any problems with Google now i want to root again but won't until I know how to fix this. Can someone help me?
