I plan to buy a Pixel XL when they come back into stock, moving from a Note3. While driving (or riding my bicycle - I live in Davis CA) I want to be able to say "Phone, remind me in 30 minutes to .....", or "Phone, snap photos until I say stop." (phone on dashboard, drunk driver ahead of me). I assume that "Phone" could be replaced by a name for the phone, as with Alexa. Please can you inform me on these issues.
