I have also been using Motrola MotoX for some time and I have had some issues with my Voyager Legend for some time for which I finally got around to address.
Frequent Disconnect Issue
There are several forum complaints that the Legend disconnects. I have the same issue with it. One thing that can help resolve this issue is to download the Firmware Updater from the company's web site. This requires a direct USB connection to your Mac or PC.
To do that, go to This Support KB Article.
The Talk Button Does Not Turn on Google Now Voice Recognition
With an iPhone or other Android phones when I press and hold the Pickup button for a few seconds, you can activate Siri or Google Now for most phones, but that stopped working (or never worked until now) on my Moto X.
This is more likely specific to Moto X with the hands-free operation mode. In my case Google Now, by default, turns off the Bluetooth Headset Mode OFF. By turning that feature on, you can gain back the mode that you can press the pickup button for a few seconds.
Here is what you need to do;
- Open Google Now uses the Google Now gesture (swiping up on the screen.)
- Scroll through all the cards until you see the last one on the bottom.
- You should now see the familiar (vertical set of 3 dots
...) setup icon on the bottom right of the screen. Tap that.
- Tap Settings
- Tap the Voice icon
- Enable the "Bulethooth headset" mode. It says Records audio through Bluetooth Headset if available. The term "record" does not sound quite appropriate, but what it means is that it can pick up the audio from the headset after pressing the pickup button.
