I just downloaded and installed the update for my Sprint HTC One. According to Google, the following feature is present:
"Just say “Ok Google”
You don’t need to touch the screen to get things done. When on your home screen* or in Google Now, just say “Ok Google” to launch voice search, send a text, get directions or even play a song"
Android - 4.4 KitKat
This does not work for me AT ALL. If I'm on my home screen and say "Ok Google", absolutely nothing happens. If I'm in Google Now and say "Ok Google", it recognizes it and starts listening, but not matter what I say, it just does a web search for it. So, if I say, "Ok Google, text Paul", it will search the web for "test Paul". If I say "Ok Google, play Pearl Jam - Even Flo", it will search the web for Even Flo.
Is anybody else having this problem?
Honestly, this is the only supposed feature in Kit Kat that really impresses me, and it isn't even working.
Okay, just before submitting I saw the fine print where it only works on the home screen on the Nexus 5. That's dumb, but whatever. The other features should still work inside of Google Now, but don't, at least for me.
