I have a brand new S9, and it can’t even do basic actions. Like Pause/Play music when I’m playing a song in spotify. Or tapping the Shazam button when I’m in the app Shazam and it’s asking ”Tap to Shazam”. And double tap is shaking it’s head like ”Nah, I wont perform this basic action for you”… A bit annoyed I guess because this feature was very overhyped.
It is useless. I suspect this “feature” is the most minimal implementation in order to collect data for more advanced features later on.
