I don't actually use Hey Siri much, because it is so unreliable. I mostly press the home button and hold for the entire duration of my voice command (because that allows you to pause in the middle of your voice command without Siri thinking you're done speaking).
I didn't know you could do that, maybe it could be useful sometime. Currently I use Siri only when I can't use my hands to interact with the phone (cooking, clothing the child, etc.).
Can you not do that? In my experience (including a test just now), speaking that phrase in a natural cadence (no weird pauses) is recognized perfectly.
That's enough for me to never want to miss 3D touch again.
>I use it all the time (at least once a day)
I use it almost daily too, you get used to that things so quickly. The thing that annoys me with Siri is that it is slow. I want to say: "Hey Siri, how is the weather today?" and not "Hey Siri" wait, wait, wait, bling, bling, wait, wait, wait, "How is the weather today?".
