Moto X Moto assist keeps coming on
Ever since the latest lollipop update, my moto assist keeps coming on asking me to what I want to say. It does this when I am listening to songs or if I am in a meeting and its in my pocket. My catch phrase quality was good and if I don't say it right it will not activate, but it will come on two or three times on my way home from work. Did not do this before lollipop update to 5.0.2. Any help? Moto X 2nd gen.
