You basically want a Nexus or a Moto X device. "The technical engine behind it is better, but the UX for using it on a locked phone isn't good" The OK Google thing on completely locked device has been working on Moto phones (and later Nexus devices) way before hands-free "Hey Siri" thing became generally usable on untethered iPhone 6s last year (at long last). And calling the incredible functionality of Google Now as "better technical engine" is quite an understatement. If iOS had this service integrated behind it, the entire world would be plastered with TV ads 24x7 calling out this "Magical" experience. Instead Apple's best effort is Siri, which works so well that this entire subreddit (https://www.reddit.com/r/Siri/ https://www.reddit.com/r/Siri/) is mostly devoted to Siri's hilarious fuck-ups. That's the reason you don't really see much marketing about Siri anymore. Instead the focus has shifted mostly on hardwares... especially the camera (which is indeed amazing).
