My ZTE Valet used to be able to use voice-to-text method of sending text messages. It no longer works for some reason. I DL'd the Google keyboard app and the microphone is there (it used to be before I got Google keyboard but it disappeared) but when I tap it, nothing happens. It used to work fine and all I had to do was speak into my phone to have it spit out the message in text.
I've looked all over the web for a fix but nothing seems to cover it.
