This voice command feature on my Nexus 5 is amazingly almost useful. Better accuracy and tolerance to ambient noise would help a lot, but let's talk low-hanging fruit instead. These are features that would be trivial to add that would vastly improve its utility.
If it listened on the lock screen, it would be far easier to use one-handed without looking at the phone. It's a trivial change. It would be easy to have a setting for it if some people don't like that. Perhaps even more important, it should listen on the GPS navigation screen. If that screen is up, I'm probably driving my car, which is when voice command would be most useful. If I could direct it to read my notifications to me and dismiss them, that would be great too.#nexus5 #googlenow
