Saying "Okay Google" Doesn't work

[AC Question]

Hello there! This is my first post on this site. I have an issue with my Google search. I am trying to say "Okay Google" and it doesn't work at all. I had not enabled the function where I can say that hot word on any screen I am on. I only say that when I am on the Google app. I am not sure if this is a factor, I do have apps that saves my battery so I am not sure if that is disabling the "Okay Google" hot word or not. Any help will be wonderful, I am using a LG G2 phone. Worked better when I had first gotten my phone. Thanks!
