When I first saw the changelog for the 4.1.1 update, I though "nice, at last I can disable those annoying voice confirmations!" But it turns out, that it disables both the voice and the beeps, and even the intentional actions like clicking the power button to get a batter level reading.
So, now you can choose between listening to those looooong voice messages, or not knowing anything at all, including guessing which NC mode I'm on, did my device connect, etc...

If this, by chance, reaches anyone actually working on those updates, please add a third mode in between -- guidance voice disabled, but leave the beeps on, so I know what's happening
