I love voice actions on the phone. I try and use it whenever I can. However, there are some times when it just doesn't work. I used to attribute it to background noise, but sometimes I'll try it in a completely silent room, and it'll say that it can't hear anything. It's extremely accurate whenever it does hear things, but sometimes this bug just pops up. I thought it was random, but I've been noticing that it seems to happen whenever I unplug headphones from it. Can anyone else confirm whether you've been having the same issue, and what you think causes it? I'd use this feature SO much more if I knew that I could rely on it to at least hear me all the time.
