This is the new thing for Smart Lock in Lollipop.
As always. Regular EU One M8. With 5.0.1 and everything (play store services) updated to the latest versions. I think that this is a more gimmicky than the other Smart Locks, but we all like different things.
First you need to make sure that Smart lock is active
- Enable a lock screen (pin/pattern/password) under Settings> Security > Lock screen
- If there is no Smart Lock even with the correct lock screen set, you need to follow THIS
Yes, I have done that. But, Trusted voice is greyed out!
If you don’t have English (US) as a primary “voice input language”, this will never ever work. Currently it’s only fully supported by English (US).
So, go to Settings > Language & keyboard > Voice input. Where for me Enhanced Google services is selected. Tap that. Under Languages you find English (US) where you tap and hold that language. This will set it as primary voice input language. You can have various combos of languages but English (US) need to be Primary language or this will not work.
And, that is pretty much it. To unlock you simply use “ok google”. Which may or may not work. Have fun!
