I've noticed that when using the new "Hey Siri" mode to activate Siri by voice, Siri seems to respond differently to certain queries than when I simply hold the home button.
For instance, If I ask Siri "When does <name of local business> close?" it normally responds with the business's hours for the current day. However, if I ask this exact same question phrased exactly the same way when Siri is activated by voice, it instead simply returns the location of the business on a map.
The key seems to be that any query initiated by voice includes "hey siri" in the query string. In theory this shouldn't make any difference, but somehow it seems to mess with Siri's interpretation. If I manually edit the string to remove "hey siri" it correctly returns the hours.
Weird, and rather annoying
