Also coming from a 1st gen X and found this thread while searching for #whattheheck is wrong with the launch phrase setup on my MXPE?!?Im coming from an original moto x where the voice assist worked really well and always woke up right away when i would say my launch phrase. I got the MXPE and it seems to never wake up well when i say my phrase, like i have to say it multiple times for it to register. Im using "Ok Google Now" as my phrase like it suggests. Ive tried the other phrase with Moto X that it has it in, but it just doesn't work well like it use to when the phone was off...Depressing at best.
"wake up moto x" it is harder than i thought to come up with SOMETHING.
Perhaps it needs to be relearned.I use the one it says is most reliable. "Ok Google Now.". And it still missed it half the time.
