" ok Google" unlock my phone??

[joe9466]

I used to be able to unlock my phone by saying "OK Google" but because of the update now it doesn't work it says that I have to unlock it for everything which kind of defeats the purpose of having an assistant, I can't navigate, listen to music, check my email without having me unlock my phone
I have uninstalled the updates because of that now he can't set up alarms which is another thing I do with my assistant.
How can I fix this??
